If you would like the Stability of Red Hat Enterprise Linux, without paying for Red Hat support, CentOS is the answer. CentOS exists to provide a free enterprise class computing platform to anyone who wishes to use it. CentOS is built from publicly available open source SRPMS provided by a prominent North American Enterprise Linux vendor (read: Red Hat Enterprise Linux). CentOS conforms fully with the upstream vendors redistribution policies and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.). CentOS is designed for people who need an enterprise class OS without the cost or support of the prominent North American Enterprise Linux vendor. CentOS 6 has been completely rebuilt using a newer build system and library checks to confirm upstream binary compatibility.
From this page you may obtain either the 32 or 64 bit version. If you are unsure get the 32 bit version which will work on both 32 bit and 64 bit PCs. Although a 64 bit operating system can provide better performance under most circumstances, unless being used for heavy graphics editing or in a heavily used production server, there is generally little if any perceivable performance difference. In instances where Windows drivers may be required via ndiswrapper, 64 bit driver s may be unavailable.
In addition to optical CD/DVDs, USB Flash Drives are very popular. They can be used in nearly any computer built since 1999, and are very useful on newer netbooks and computers without optical drives.There are currently two major types of USB Flash Drives we currently use. The standard USB 2.0 drives from Kingston shown on the left, and the next generation USB 3.0 Flash Drives from Kingston shown below on the right. Both types of drives can be used in any USB port from the early 1.1 specifications of the late 1990s through to the latest USB 3.0 specifications that came out in 2010. The only practical difference between the two is their speed when plugged into a USB 3.0 port, which allows the Kingston USB 3.0 Drives to save and read data 5-6 times faster than the Kingston USB 2.0 Flash Drives.
The Mobility Kit, shown here on the left, consists of a small "Micro" SD Card which inserts into a small USB Flash Drive adapter, or standard SD adapter. This allows it to also be used as a standard SD Card, or USB 2.0 Flash Drive. This is a great option if you want to be able to use it in the widest variety of computers and hand-held devices, or if you just want a nearly invisible USB Flash Drive that doesn't stick out.
When ordering flash media it is strongly recommended to select either the Priority Mail or Express Mail delivery option.  Although you are allowed to select first class mail at checkout time, we will not replace any items lost in the Postal System. In most instances undelivered orders are returned to us and we can contact the customer, let them know, and arrange re-shipment, but not always. Priority and Express Mail packages can be tracked Online so if something goes wrong we can track them down.
Flash Drives and Media Kits are ordered from Distribution on Mondays and Thursdays, with shipments generally taking three days to arrive. Please allow up to a week for these items to be processed, pre-tested, and shipped to you from On-Disk.com.
32 Bit, and x86 refer to Intel, and Intel Compatible, computers. These include computers using Intel, AMD, and VIA processors.
64 bit, x86_64, and AMD64 designations refer to a 64-bit extension to the existing x86 architecture. A 64 Bit Intel, or Intel Compatible, computer can run either a standard 32 bit operating system, or a 64 bit optimized version.
The performance gain from using a 64 bit operating system is virtually imperceptible in most instances. Where we could possibly notice a difference would be when the computer is under a heavy load such as when running high-end applications which may require massive system resources, or a highly over-tasked Internet Server. This is because the majority of the performance gain is due to the road the internal data travels on being twice as wide as on 32 Bit hardware, as well as newer/faster hardware that supports it. In normal computing environments, very little performance increase can be attributed to the CPUs enhanced 64 bit instruction set itself.
One remaining drawback to using a 64 bit operating system is that there are still instances where hardware support or software may not be available.
PowerPC, often abbreviated as PPC, was used by Apple's Macintosh lines from 1994 to 2006 (before Apple's transition to Intel). If you have an older Apple, or Apple Compatible, computer from this time period look for products offering PPC options.
The computer type option on software pages (not operating systems) is fairly easy to select. Just match the computer type with the operating system installed on your computer. If you are not sure if you have a 32 or 64 bit installation use one of the methods below:
Microsoft has a guide for Windows 2000 and newer versions: http://support.microsoft.com/default.aspx?scid=kb;en-us;827218 All older versions of Windows are all 32 bit.
Under Linux run uname -a in a terminal window.
Computers without a working operating system: Pay attention to the display when the computer is turned on, it will normally show one of the designations listed above. Otherwise you may need to press whatever key it tells you to use to enter the BIOS (AKA startup options). Once in the BIOS the type of CPU should be displayed.
Orders ship out twice a week, on Tuesdays and Fridays.

Technical Support Options:
No-cost technical advice and support is available for nearly any piece of software, including operating systems. In many instances you will also have support available locally. The key is to know these options exist, and have enough basic information to be able to find them. Whether looking for assistance with a computer operating system, or software running on the computer, there are outstanding free options available. The first place we can begin seeking help is Online. Most operating system and software developers have Online forums in place specifically to assist you. These Online support forums allow you live and on-demand access to a wide range of technical guidance from industry experts. You can usually find support forums by visiting the developer's website. In some cases you can just do an internet search for the item you are needing help with, followed by the word "forum" to find relevant information. In most instances, for the products we have available, a link is provided for you under the "Support" tab on the listing page for that particular item. The advantage of support forums is in the numbers and expertise...your situation can be viewed by many people, and only one needs to know the answer for you to find a solution. Online support forums are also followed, in most instances, by those who actually write the piece of software, or have a hand in developing the operating system. These folks are the "real-deal", not just an hourly paid employee on the other end of a phone somewhere. Nearly every Linux, BSD, and Open Solaris distribution has a user forum to help with any problems that may come up. There are also several very good general content forums such as :http://www.linuxquestions.org and the Nixcraft Linux Tech Support Forum - great places to get help with just about every operating system other than Microsoft Windows, as well as applications that run on them. For the more technically adventurous there are forums such as The UNIX and Linux Forums and http://www.unixforum.co.uk/. MAC users have the great MAC OSX support forum available to them, as well as the Apple Discussions, and MAC Forums.
And don't feel left out if you use Microsoft Windows, you have Online support forums at your disposal as well, but you do need to be on the lookout for forums created just to sell you antivirus or spyware solutions. The most reputable is the Microsoft Forums. For assistance with a non-microsoft product under Windows you may sometimes get better results at other locations such as the Tech Support Forums. Another great place to get free technical support is through local user groups. Since the early days of computing groups of people have been getting together to explore all the geeky things they can do with their computers. In the past few years the number of user groups, and members of existing groups, has exploded fueled by the growing popularity of Linux and and open source software. There are several types of computer user groups, and to find ones that meet near you. A quick internet search can help find a group near you. For instance a simple search like linux user group gives excellent results. I selected Linux User Group (also known as LUG) because from my experience a Linux user group can, and usually will, assist with just about any computer or gadget related problem you might have. LUGs normally have regular meetings which everyone is welcome to attend, as well as "Install Fests" periodically throughout the year. An install fest is an event where they will even install your Linux selection onto your computer for you, as well as give you advice on which distribution may best suit your circumstances. Although it's great to have face to face conversations with the people who are helping you, the majority of assistance members give each other usually takes place on a mailing list, which offers real-time answers to questions. Using the mailing list for support can be a great lifeline if you happen to live some distance from the nearest group and can't attend regular meetings.
