5.9.2017 – Php is a an easy-to-learn programming language. What might come in hand to many internet programmers, are cron jobs, that might be run simultaneously using cron, in one-minute intervals. One problem may arrive, when 2 same scripts start to run in the same time. PHP function getmypid may come in hand then, because this function is able to provide you current ID of running script. When the script is running, you can easily take ID of current script, and work with this function in another scripts. For example, you can easily save ID of running script, and calling cron job can first look, whether previous instance is still running. Based on this information, cron job can start to run a new instance, or decide to stop another instance, until previous ID is not available in the system (the cron job finished).

The theme of things offered on the flea market is quite unique, unlike the normal market there are different rules. In the flea market you can find almost anything, you can remember. Things as diverse as a 30-year-old mixer or brochure, washing powder or Wallachian cakes, tires or old books, so I could go on endlessly. But all of these things combine one thing in the eyes of shoppers, even though the shoppers themselves do not form a single group with the same interests and goals and the market can perceive differently. One could say that what they are all about is the desire to find a real treasure here. It does not matter if it is a good package of biscuits or old glass at a low price, it is important to get the thing you want in the most convenient way. And the word advantageous here plays a significant role. We have to take into account that if something is good, it is not a generally valid property, but rather a set of several factors (economic, aesthetic, emotional, etc.) that define the situation individually for each individual. When we talk about second-hand things, the question of the value of things and, therefore, the benefits of buying them becomes even more complex.
The things on the market are usually spoken as commodities. From a flea market perspective, however, this is again quite specific and there is no exact definition. There are also things that cannot be a commodity by nature, and if they happen, they will lose by their very nature what they have been different from other things. Such things include, for example, various religious subjects. Some scientists are likely to include these items in a special group of commodities called "commodities by diversion" and which forms a subgroup of so-called "commodities by metamorphosis", whose main feature is that, although originally it is things that did not have the status of a commodity, nevertheless happened to them. In addition to this group, there is also a group of commodities by destination, primarily commodities and ex-commodities.
Thus, we can see commodification as a process that results from the interaction of time, cultural and social factors. All of these factors are exacerbated in the flea markets. However, before I get to specific examples, there are still some specificities that are linked to commodity markets. Already above, it has been said that under certain circumstances they can become commodities and knowledge, and they play a significant role in flea markets on several levels. The use of knowledge confirms and shows it in its commercial form - that, during trading, the advantage for one often means loss to another.
Today we will share with you the results of testing some of the extensions for the Joomla! Editorial system, which promise to speed up web loading and other optimizations.
Three of them, Speed Plus for Joomla, SpeedBooster for Joomla and Virtuemart Speed Booster, are paid and developed by CodingMall. Other jBetolo and JCH optimized extensions are free and promise a truly wide functionality.
According to the authors of the plugin, the Joomla website is slower than static html due to the large number of database queries.
The SpeedPlus for Joomla plug-in makes it cached by some modules you choose in the plug-in settings to speed up both the Web site and the eshop running on Virtuemart. Its creators promise to reduce the number of queries on the database by 81%.
The SpeedPlus plug-in is £ 49.99 and the license is limited to one domain.
When using plug-ins, you may not have Joomla! and compression of gZip. It is not recommended to cache dynamic modules such as Login, Virtuemart cart, Who's online, etc.
Plugin SpeedBooster for Joomla costs for one domain £ 49.99.
Just like the SpeedPlus plugin, SpeedBooster for Virtuemart is based on caching certain modules.
Creators promise to reduce the number of SQL queries by up to 80%, and reduce the page load time by up to 70%, lower CPU load and less cache space for cache files (only about 10KB per product in your e-shop).
Just like SpeedPlus, Virtuemart SpeedBooster costs £ 49.99 and the license is limited to one domain.
The above plugins are compatible with the Joomla 1.5 Native, 1.6, 1.7, and 2.5 versions
The server should be installed with ionCube loader, Apache version 1.3.x or higher, MySQL version 4.1.18 or higher, PHP 4.x / 5.2.x and at least Joomla 1.5 or higher.
The creators recommend using all three plugins at once for the best effect. For all three plugins, they will send you a full-featured 15-day trial on demand to help you set it up.
You can also buy SpeedPlus and SpeedBooster at a bargain price of £ 89.99.
If something works for 100% Codingmall Plug-ins, then it's their support. Whenever I discovered a problem, I quickly responded to it (by email) and solved it with programmers, so only thanks to my suggestions the plugin was updated several times.
Frankly, given that the measurement results for one and the same website vary greatly in each test, I'm not able to say 100% that the plugins have the promised effect. We personally felt that the only thing that had a visible impact was to turn on the SpeedPlus for Joomla plug-in. The other two are does not have such impact on the loading rate, in my opinion.
In most of the tests, Speed Plus for Joomla has been able to raise page scores from some 50 to 70. But for some tests done over Webpagetest.org, the same page achieved similar results with or without plugins. The results differed a lot from day to day, but even when I tested the site a few minutes in a row ...
After installing the SpeedPlus plug-in, it broke CSS formatting on some pages, so the "Insert to Cart" button was instead of the original appearance in such an ugly box, and only half a button was shown on the product list in the category. They solved this problem quite quickly. After the next update, the Insert button stopped working completely. But they have solved this problem, so the final version is already usable.
I promised a lot from the jbetolo plugin because, despite being free of charge, it promises a combination of plugin functionality from Codingmall and has had a large number of positive ratings in the Joomla Extensions Catalog.
According to its creator, this plugin can:
However, as the creator states on the official site of the jbetolo plugin, you cannot expect the plugin to work immediately without the proper settings. And there will be a hitch. When I set up what I wanted from the plugin, it really made a significant acceleration, the page speed score of the site rose to 80 - but at the price of CSS broke just as SpeedPlus did, before its makers made an update, which fixed it. I tried to gradually turn on individual features, but I did not manage to get some correction. So I wrote to the author what a problem, and he really replied. He promised to look at it when I sent him access to the eshop. But after that, there was no response. So judge yourself. Try out the plugin, and if you can manage its relatively complicated settings so, that it will have a visible benefit for your website or online store, then you are lucky one.
By far the greatest hope I put into the JCH Optimize plugin, which should offer not only what the above mentioned plugins can do, but also create a so-called CSS sprite, a combination of images on the background of the web page, which should significantly speed up the loading of the web. Even this plugin has a lot of positive reviews. Here you will find a complete list of functionality of this plugin. Unfortunately, it has no effect on speeding up the load on the web either. But you can try it for free, so nothing bad to say.
Finally, I would say that none of the tested extensions for Joomla! made the miracles which I had expected from them. But who knows, maybe it really just wants to play with their settings and adapt them to your website or eshop.
According to the unconfirmed information by producer (and unfortunately, Apple cannot be expected to confirm this and apologize), there has been a very rare event, when one of the owners (known as Mrs. Wu) of the new iPhone 8 Plus exploded during charging.
It was supposed to happen when the 70% charge state of the battery was connected to the supplied charger, and then 3 minutes later the phone burst. Apple uses batteries from different manufacturers, namely Samsung SDI, Amperex Technology Limited and LG Chem. The first two (one of Samsung's subsidiaries, the second independent manufacturer) were battery suppliers to the problematic Samsung Galaxy Note 7, where batteries exploded, at least inflated, or just burned quite often.
But we need to wait, if this problem escalates in the case of Apple, or, on the contrary, we are concealed of some important fact. According to the photos, it does not look like some kind of fatal explosion with burning. Apple is currently investigating the incident.
The struggle of printer manufacturers not only with producers of non-genuine, cheap cartridges, but paradoxically with their own customers is, it seems, infinite. Others tried it and Hewlett-Packard was ashamed in 2016. At that time, the use of non-genuine cartridges in printers was banned, and HP was grappling with a giant wave of criticism. HP has now released new firmwares that are once again correcting this once again emerging problem.
Printer owners with non-genuine cartridges cannot print. Whether it has been a misconduct or intent, users of the following HP Hewlett-Packard series have to deal with the problem: OfficeJet 6810, 6820, and OfficeJet Pro 6230, 6830, 8610, 8615, 8616, 8620, 8625, 8630, 8640, 8660 , X451dn, X451dw, X476dn, X476dw, X551dw, and X576dw.
If the error message appears to the printer user, there are several possible causes. In addition to some HP original ink defects, the problem is related to non-HP security chip in printer cartridges (either non-genuine cartridge or HP cartridges). In this case, the printer detects a problem and prevents further printing, with the need to replace the cartridge. Everything is due to the feature of printers called Dynamic Security. The recommended procedure is to update the firmware that disables Dynamic Security by downloading it from the HP Web site.
Hewlett-Packard has a slightly more modest tone after years, and there are court verdicts that say the printer manufacturer does not have the right to cut users from alternative cartridges. So HP just recommends using genuine corporate supplies, with a site where authenticity can be verified.
It is necessary for HP to add to the good that it is OK that it does not intend to guarantee the quality and durability of the print or the life of the print heads in the case of the use of other manufacturers' cartridges. It's similar to when a car manufacturer is also not responsible for fuelling a fuel from a dubious source (especially diesel) instead of a proper one. And especially for inkjet printers, it is appropriate to add that there are more and more models that do not have classic print heads with small cartridges, but large ink cartridges where large amounts of ink are poured - and HP is among those manufacturers.
Facebook announced at the beginning of March 2017 the opening of a new advertising platform for advertisers - an Instagram Stories ad. This is a long-awaited change that will be appreciated by all brands and businesses that are interested in Instagram users' direct involvement in popular personal stories. We have just tested this hot novelty. Are you interested in how it was?
The new ad platform was available through the API, and later will be available to all advertisers. Facebook now offers so-called "Reach" campaigns that are ideal for branding companies and brands. Gradually, however, it plans to deploy ad formats such as web clicks, web conversions, or application installs.
To create this ad, an image or video dimension of 9:16 or more (600 pixels in width at a minimum) is required. This is the first full-screen Instagram ad format. You can use both photos and videos.
And these are the exact specifications of the new format:
Based on these specifications, it's clear that the ad is a very good addition to brand campaigns. With a length of up to 15 seconds and a full mobile screen overlay, this ad will become a great addition to TV campaigns. It can also be expected that for younger targeting campaigns, this format will gradually replace TV advertising.
In several Insta Stories tests, we've managed to get 1,000 impressions for about $ 1 in the 10/10 relevance score. That's $ 100 with 100,000 users hit. In the meantime, it is not possible to post clicks (this is the next update), but now the CTR (clicks on the advertiser profile from the top logo) is now 1 - 2%. This is a cost-effective ad for Instagram ads, so the format is no more expensive. Thus, the ad has the great potential to become part of all brand campaigns.
Insta Stories do not offer an active click at this time, so we would recommend an emphasis on the emotion and brand of the company. You want to capture and keep product or brand awareness for as long as possible.
The advantage of the new format is the fact that Stories are very well viewed and users are not used to advertising on this platform (Insta Stories). So the impact on brand awareness can not only be very interesting now. This type of ad could be compared to In-stream ads on YouTube that have a great impact on brand awareness and subsequent shopping behavior when properly scheduled.
2. Does the policy present accurate details of user data collected?
4. Are all relevant laws the site abides by included in the policy?
National, federal, and/or state privacy laws that govern the practices of the site must also be mentioned in the policy.
5. Include effective date and opt-out options
As you plan on setting up your site, you will find the checklist items in this post highly invaluable to making hosting and policy decisions that will ensure a healthy and safe growth of your website.
To own and operate your own server requires careful planning, detailed budgeting, and the technical prowess to maintain it. There can be multiple hardware and software hurdles to overcome, plus the daily risks of viruses, malware, and hardware failure.
Selecting a server platform requires careful preplanning. You first must determine exactly what software you intend to run, what storage capacity you will need, and what kind of processing speeds you will require. You also need to decide how fast data may need to move into and out of your server, to determine what kind of network interface will be needed. Getting all these factors covered with room for growth is critical to your success.
Server platforms can utilize one of a variety of operating systems and performance applications. Windows, Linux, FreeBSD and others all provide powerful solutions to server needs. Choose the system you are most familiar with, and where you can handle all the setup and configuration with confidence. Some are free, while others have substantial costs. Some excel at web applications, others more for dedicated software. Find a platform that will accomplish everything you need to do, at a cost you can afford.
One of the most demanding aspects of running a server is the physical environment. Heat, humidity, vibration, and other physical factors can reduce a server's lifespan considerably. Most servers are maintained in carefully controlled network data centers or safe rooms. Since a server may also contain potentially compromising customer information, security is also a concern. It's also important to situate your server in a location with sufficient network access. Finally, you need access to a stable and redundant power source. Be sure you have an uninterruptable power supply to keep your machine active during outages and protected from surges.
Loading and Monitoring
Once your server is in a suitable location, it's time to load all your particular software and configure it for your needs. Your network connection provider can assign specific IP addresses and other network configuration information to get online and to program your software. If you're running a web server or email, you'll also need a DNS server programmed with your data so users can find you. Your upstream provider should also be able to assist you with that information.
Once your server is in operation, you'll also want to enact some monitoring software to alert you of any problems, usage issues, or unusual activity. Most monitoring programs include the ability to email, text, or call as needed to bring the issue to your attention quickly. Having an effective system in place can reduce costly downtimes.
Protection and Recovery
Protection against viruses, malware, and other software attacks is crucial. Be sure to configure your protection software to scan all data as it arrives, keeping the malicious program from accessing your data or operating system. Perform routine scans of all drives and other devices, and keep logs for reference. Knowledge is power.
You also need to have a sufficient backup and recovery system in place and be sure it is scheduled to run regularly. If downtime is an issue, many server owners also keep spare hardware components and a pre-loaded boot drive on hand, ready to install in case of failure.
Keeping your system running is a challenge, but can also be be very rewarding.
Facebook is such an integral part of our everyday lives, that the idea that it can have "privacy concerns" is not something most people would even think about. In fact, many people don't think about it. While it has been common knowledge that Facebook CEO Mark Zuckerberg was called to testify in front of congress over concerns of fake news, election hacking, and not being very careful with the data the company collected from its users, most people haven't boycotted Facebook or even so much as changed their settings. Truth be told, Facebook usage is up since the testimonies and if you're a shareholder in the company you had a very good month all things considered. Still, there is no denying that Facebook came dangerously close to have a full blown revolt against the site, and they have committed to changing for the better.
We know this because they are showing ads decrying things like spam, fake news, and clutter. They promise to focus more on showing baby videos and pictures of your dogs. To get back to connecting people. Because, "then [Facebook] brings people together, it makes the world a better place." Many will properly notice this is more of an apology tour video without too much useful information, as they don't elaborate on exactly how they plan to do a better job of "bringing people together." Through several small (but significant) changes. First, it appears the days of apps and extensions having access to your personal information (and contact list) are largely over. Though some "trust" apps will still have access to all your personal contacts, the vast majority of apps will not even be allowed to ask if they can have access to that information.
Also, the settings for your profile page are much more detailed and gives you a greater sense of control of who views your stuff. Sensitive information like where you grew up in high school, your relationship status, and your political beliefs can be turned off to all but the few people you deem worthy (mature?) enough to view. If by some miracle you are new to Facebook, virtually all of your personal information is now private from everyone on your friends list unless you choose to go into the settings and change them. One of the biggest changes comes with the 'Trending' bar, which used to display topics that were trending on Facebook. However, since stories that were not actually true could trend all the time (like the existence of a Dreamcast 2), Facebook has made it so that a story will not trend unless it is verified by a major, trusted news source like CNN or NBC.
This has caused some minor controversy as some users have pointed out the liberal slant of the media (who sometimes chooses to ignore certain stories that don't fit "the narrative"), but it should be noted that Fox News is considered a 'verified source,' so one could argue there's some diversity there. Facebook got hit hard by the election. There is some debate whether or not the site was truly hacked and affected the outcome of the election, but the company wants to make one thing clear: they've heard the accusations, and they want to ensure that perception isn't around next year (or ever again).
Every device in contact with a computer network and using Internet Protocol for communication has an IP address. Internet protocol refers to the process of transporting user data and information throughout networks. An IP addresses is a numerical designation essential to the internet. The internet we know would not exist without IP addresses. The two essential roles of an IP address are identifying host or network interfaces and representing the address for locations.
The initial IP addresses were Internet Protocol Version 4, or IPV4. IPV4 still accounts for most IP addresses. Internet Protocol Version 6, or IPV6, is expanding and currently accounts for roughly 20% of all IP addresses in use. IP address space is carefully monitored on a global scale by the organization Internet Assigned Numbers Authority (IANA). Five regional Internet registries (RIRs) have the responsibility of monitoring their assigned areas. This includes internet service providers. RIRs each received blocks of 16.8 million IVP4 addresses to distribute as needed. IPV6 was created in response to the rapid decline of available IVP4 addresses.
IPV4 addresses are now in high demand due to their scarcity. Business owners want the IPV4 addresses and often have preferences for what address and range they purchase. A range of IP addresses is much more valuable to a growing business or organization. Expanding an online presence requires a sufficient number of IP addresses. IP addresses are associated with location so a business or organization does not want a misleading address. The geographical location of an incorrect IP address can cause search engines to associate the site with the wrong location. Customers would also suffer some confusion and possibly lose trust in the company. The results could be even worse if different websites for the same entity were associated with different geographical
People who wish to buy an IPV4 IP address must contact a company selling its own supply of IPV4. Many organizations set up shop to act as brokers in the IP address market. The brokerages help a client locate an IPV4 address fitting the client's requirements and location. Excessive numbers of IP addresses were given to some businesses in the USA. Brokerages often use those businesses as a resource for leasing address range. The owners are not going to sell those addresses. It is a reliable and effortless income on their part.
Renting an IP address range is very simple. Brokers are everywhere and they make themselves accessible to future or current customers. The difficulty occurs when there are no more IP addresses in the desired location. Cost is another factor. Some brokers, such as
Brokers are everywhere and they make themselves accessible to future and current customers. Concerns of brokers hosting illegal business deals or working on the black market were laid to rest. It is a completely legitimate business.
The difficulty occurs when no range of IP addresses are available in the location desired by the client. It is simply a fact of the business. Everyone will not get what they want. Cost is the other significant factor in purchasing a range of IP addresses. GetIPAddresses.com offers buying, selling, and leasing. they also offer IPV4 and IPV6 addresses. The IPV4 addresses are much more expensive than the IPV6 addresses. Leases can run up to five years. This is an advantage for most businesses or organizations but it could easily become a negative. The original owner of the IP address still owns it and can take it back at anytime once the contract is breached by missing payments.
To become an Internet Service Provider or ISP, there are a number of components that must be in place. Selecting or acquiring each one is critical to the success of your operation. Be sure to consider each one carefully, and assure your plan covers all bases before you proceed.
An ISP consists of these components:
Let's take a look at each in detail:
Your datacenter may be as advanced as a dedicated, environmentally-controlled local facility with racks of hardware and high-capacity connectivity, or as simple as a single server or site hosted by an independent provider. This all depends on what services you will be offering your customers, and how much server capability will be required.
Your local service will require a dedicated, high-capacity connection to the Internet, usually contracted from a larger upstream provider. This can come in many forms including telephone circuits, DSL, cable connections, or a wireless link. Finding and partnering with a suitable upstream provider is critical to the success of your operation as downtime, routing issues, IP allocation, and other operational issues must be resolved quickly to keep your customers happy with your service.
One of the most important aspects of your service is called the 'last-mile' connection, or how you connect to your customers. In some areas, you may be able to contract in bulk with local DSL or Cable providers to resell their service as your own, which they offer at a discount since you will manage all tech support and billing for your customers. In some unique locations, you may have wired access available to your customers, such as in a hotel cluster or apartment building complex.
Another popular method of connecting to potential customers is through a wireless link. You would determine a location high up on a building, tower, or other elevated structure to mount a transmitting antenna, and sell or lease your customers a smaller personal antenna that connects to your tower. Your transmitting antenna has another smaller antenna that connects it back to your facility and into your main upstream connection to the Internet. Once your customer is connected to your tower, they are online. There are a number of wireless technologies specifically designed for a small ISP, with monitoring and management features built-in.
Once you begin to add customers, you need an efficient, manageable system for tracking customers, invoicing, and receiving payments. You can adapt many small business software packages to your operation, or contract with a software provider for a custom package. You also need to develop policies for dealing with non-payment, canceled service, and transfers to new locations.
You will also need to make customer service and technical support available to your customers, whether through web chat, email, telephone, or in a local office. Be sure to allow sufficient time and resources to help your customers achieve and maintain a stable connection, plus deal with any hardware or software complications or viruses.
Of course, this all assumes you already have a legally established business, but should serve as a technical guide to your success as an ISP.
Border Gateway Protocol (BGP) is designed to manage the routing of packets across the Internet. This is done through exchange of routing information between certain routers. This protocol ensures correct routing for optimal reachability, while directing packets between systems. The latter are essentially anonymous networks (AS) that are managed by service providers or single-based enterprises. The traffic is routed within single networks is known as internal BGP. However, BGP also connects one autonomous system to other autonomous systems; known as external BGP.
BGP ensures network stability, which results in routers adapting to effectively send packets through other reconnections. This, of course, is if one Internet path goes down and is unable to handle the routing of packets. Similarly, BGP bases its decisions on existing paths, along with network guidelines and/or policies. These rules are configured and governed by network administrators. For each BGP router, a standard routing table is maintained to transmit packets in transit. These tables are also used to correlate with separate routing tables, which are known as routing information bases (RIB).
RIB is essentially a data table, which is stored on servers within the BGP routers. RIB not only contains route information, but also manages updates to tables as changes happen. In a nutshell, the RIB consists of vital information stemming from connected external peers – along with internal peers. BGP protocols are also based on TCP/IP and client-based servers to effectively transmit routing information. Client-servers play a pivotal role in this process, since they initiate BGP sessions by sending requests to specific servers.
BGP protocol is an intricate and detailed process that has many multi-faceted layers. However, the core aspect revolves around sending updated router table information in the event something changes. This too only pertains to affected information as BGP does not have built-in discovery mechanisms. This means all peer connections must be set up manually – with programmed addresses at both points.
BGP also makes path decisions based on its characteristics and hop counts. Similarly, it is based on current reachable levels, however, can also facilitate multiple paths if present. With the latter, BGP is then used to communicate desired organizational paths in and out of their networks. This usually pertains to major hosting facilities, but also relates to P2P agreements and route advertisement behaviors. As a form of machine-learning, BGP even defines arbitrary tags – which are known as communities. These tags are utilized to control certain agreements and path behaviors among peers or shared routers.
BGP-4 current versions are designed to support classless inter-domain routing (CIDR). Similarly, these versions also support IPv6, which were certified back in 2005. CIDR and IPv6 enable the continued use of IPv4. CIDR is also able to facilitate more addresses within networks, which are far superior to current IP address assignments and schemes.
ClamAV is short for Clam AntiVirus, which an open source antivirus program which functions on both Windows and Linux platforms. This toolkit has the power to detect a range of malicious scripts, such as viruses, trojans, malware, adware and spyware. It is primarily used to provide protection to mail servers by serving as a mail scanner.
ClamAV was originally developed for Unix systems, so it has a wide array of 3rd party versions to offer. These include Solaris, OpenVMS, MacOS, Tru64, Linux, BSD, AIX and HP-UX. As versatile as ClamAV is, it is also functional on Windows, and that version is also free. Most users feel that Linux is a very low-risk environment when it comes to security threats such as viruses, as most are designed to deploy on Windows machines. This is why the demand for Unix-based antivirus is relatively low, so people aren't really prepared to pay for security measures.
If there is sensitive or sentimental data and files on your machine or network and privacy and safekeeping are major concerns for you, the ClamAV will assist you.If you have a dual boot system whereby you log into both Windows and a Linux-based system on the same machine, then this program is especially useful for you. While logged into Linux, you can safely scan all your partitions, including the Windows data, to ensure that your machine has not been compromised. If the Windows system does have a virus, then by accessing the files without logging into Windows, you are minimizing the risk of the virus spreading or damaging your files when you log in.
ClamAV boast a range of useful tools and functionality. Its utilities include a database which updates automatically, a command-line scanner, and a multi-threaded daemon that is scalable, operating on a shared antivirus engine library. It also has a Milter interface, which is for scanning on demand and for outgoing mail. ClamAV supports a variety of formats, including RAR, Tar, Zip, Gzip, Cabinet, OLE2, Binex, and CMH. Additionally, it supports an array of office document formats, including RTF, HTML, MS Office files and sheets, and PDFs.
As free software goes, ClamAV has established itself as a reliable security measure for detecting the majority of security threats. It is especially good at detecting phishing emails. Unfortunately, it is also known for returning a lot of false positives, more that its competitors, so be aware of this when you install it on your server.
That being said, ClamAV stands tall and proud among its competitors. Shadowserver tested more than 25 million samples in 2011, using ClamAV and a score of other antivirus programs. ClamAV was able to successfully detect 76.6% of the malicious software.
It is a common belief that a server is just a regular desktop computer. Although a normal desktop computer can run a server operating system, it isn't actually a server. The technology and software for a server are very different than a normal desktop. Desktop computers are focused on running a user-friendly operating system and software is meant for tasks an individual would want to do on a PC. A server is built to manage, store, send and process data 24-hours a day. Most servers are dedicated, which means they have no function other than server tasks.
One essential different between servers and desktops is the ability of a server to run 24 hours a day, 7 days a week, 365 days a year. Most desktops will not be successful if re-purposed as servers because they can't hold up to such constant use without interruption. Servers have redundant power supplies and in ideal situations there are at least two power supplies so a server is much more likely to have power in case of losing one source.
Computers do not like heat. Overheating will cause rebooting, freezing, and poor performance. Air circulation is the method of choice for avoiding overheating. A server has fans on the CPU and power supply, and also separate fans for hard disk drives. The power supply of a conventional desktop is not capable of supplying the amount of fans a server needs.
Server motherboards have integrated RAID-controllers to allow several physical disks to act as one unit. This enables a possible 'hot swap,' which is the act of replacing a hard drive without shutting down or interrupting work. Users usually don't even notice an interruption. A conventional PC can have a RAID-controller but it will only support two hard drives in most cases. Additional RAID-controllers can be added but this brings the complication of overloading the power supply and overheating because there are not enough fans or air circulation is blocked. A 'hot swap' is not possible on a desktop. Data loss can be avoided but work will be interrupted.
The server chassis is usually constructed with steel over 1 millimeter thick. This increases mechanical strength and reliability and reduces noise coming from the server. The thick steel construction protects the server and reduces the risk of injuries while working with the chassis or adding hardware. The chassis of a server is constructed to allow efficient air flow and the additional of more hard drives. The thin and sharp steel cabinets of a conventional desktop do not provide much protection and can cause injury while trying to quickly made repairs or additions.
Expansion is a key consideration for a server. A businesses hopefully looks forward to expansion. Motherboards for servers have slots for additional processors and memory modules. A server chassis contains bays for additional hard drives. Additional space using a conventional motherboard and chassis for a desktop quickly runs into problems with crowding and blocking air circulation. Conventional motherboards have only four slots for additional RAM while bays for adding hard drive disks is limited to six.
The use of a server instead of re-purposing a standard desktop for use as a server is clearly the best choice when considering practical concerns. The server will be more expensive initially but over time the expense is justified and five years down the road a business will usually see that the server was also the economical choice. Upgrades and expansions to the server will occur at less cost over time than attempting to continually alter and maintain a desktop in a function it was never meant to serve.
