2.1.3. Which Files Do I Download?
2.2. Obtaining Fedora on CD or DVD
This chapter explains how to get the files you need to install and run Fedora on your computer. Concepts in this chapter may be new, especially if this is your first free and open source operating system. If you have any trouble with this chapter, find help by visiting the Fedora Forums at www.fedoraforum.org/.
The Fedora Project distributes Fedora in many ways, mostly free of cost and downloaded over the Internet. The most common distribution method is CD and DVD media. There are several types of CD and DVD media available, including:
Most users want the Fedora Live image or the full set of installable software on DVD. The reduced bootable images are suitable for use with a fast Internet connection and install Fedora on one computer. Source code discs are not used for installing Fedora, but are resources for experienced users and software developers.
Users with a broadband Internet connection can download ISO images of CD and DVD media or images of USB flash disks. An ISO image is a copy of an entire disc in a format suitable for writing directly to a CD or DVD. A USB flash disk image is a copy of an entire disk in a format suitable for writing directly to a USB flash disk.
For more information on burning CDs and DVDs, refer to Chapter 3, Making Media.
If downloading the Fedora ISO images and burning them to CD or DVD is impossible or impractical for you, refer to Section 2.2, “Obtaining Fedora on CD or DVD” to learn about other ways that you can obtain Fedora.

2.1. Downloading Fedora

2.1.1. How Do I Download Installation Files?

Download Links

To follow a Web-based guide to downloading, visit get.fedoraproject.org/. For guidance on which architecture to download, refer to Section 2.1.2, “Which Architecture Is My Computer?”.
Fedora software is available for download at no cost in a variety of ways.

2.1.1.1. From a Mirror

The Fedora installation files are freely available from web servers located in many parts of the world. These servers mirror the files available from the Fedora Project. If you visit download.fedoraproject.org/, you are redirected to a mirror, based on a calculation of which mirror is likely to offer you the best download speed. Alternatively, you can choose a mirror from the list maintained at mirrors.fedoraproject.org/publiclist. This page lists mirrors according to geographic location. The mirrors geographically closest to you are likely to provide you with the fastest downloads. If the company or organization that provides your internet access maintains a mirror, this mirror is likely to provide you with the fastest downloads of all.
Mirrors publish Fedora software under a well-organized hierarchy of folders. For example, the Fedora 17 distribution normally appears in the directory fedora/linux/releases/17/. This directory contains a folder for each architecture supported inside that folder, in a folder called iso/. For example, you can find the file for the DVD distribution of Fedora 17 for x86_64 at fedora/linux/releases/17/Fedora/x86_64/iso/Fedora-17-x86_64-DVD.iso.

2.1.1.2. From BitTorrent

BitTorrent is a way to download information in cooperation with other computers. Each computer cooperating in the group downloads pieces of the information in a particular torrent from other peers in the group. Computers that have finished downloading all the data in a torrent remain in the swarm to seed, or provide data to other peers. If you download using BitTorrent, as a courtesy you should seed the torrent at least until you have uploaded the same amount of data you downloaded.
If your computer does not have software installed for BitTorrent, visit the BitTorrent home page at www.bittorrent.com/download/ to download it. BitTorrent client software is available for Windows, Mac OS, Linux, and many other operating systems.
You do not need to find a special mirror for BitTorrent files. The BitTorrent protocol ensures that your computer participates in a nearby group. To download and use the Fedora BitTorrent files, visit torrent.fedoraproject.org/.

Minimal Boot Images

Minimal boot CD and USB flash disk images are not available through BitTorrent.

Verify your download

Once you have downloaded an ISO, verify it for security and integrity. To follow a web-based guide, visit https://fedoraproject.org/en/verify.

2.1.2. Which Architecture Is My Computer?

Releases are separated by architecture, or type of computer processor. Use the following table to determine the architecture of your computer according to the type of processor. Consult your manufacturer's documentation for details on your processor, if necessary.
Table 2.1. Processor and architecture types
Processor manufacturer and model Architecture type for Fedora
Intel Atom (see note below,) Core series, Pentium 4, and recent vintage Xeon; AMD Athlon, Duron, some Semprons; and older; VIA C3, C7 i386
Intel Atom (See note below), Core 2 series, Core i series and Xeon; AMD: Athlon 64, Athlon II, Sempron64, Phenom series, Fusion series, Bulldozer series and Opteron; Apple MacBook, MacBook Pro, and MacBook Air x86_64

i386 Works for Most Windows Compatible Computers

If you are unsure what type of processor your computer uses, choose i386.
The exception is if your computer is a non-Intel based Apple Macintosh. Refer to fedoraproject.org/wiki/Architectures/PowerPC for more information on using Fedora on these systems.

Intel Atom Processor Architectures Vary

The Z Series and N200 Series Atom processors are based on the i386 architecture. The 230 and 330 Series and the rest of the N Series Atom processors are based on thex86_64 architecture. Refer to ark.intel.com/products/family/29035 for more details.

2.1.3. Which Files Do I Download?

You have several options to download Fedora. Read the options below to decide the best one for you.
Each file available for download in a Fedora distribution includes the architecture type in the file name. For example, the file for the DVD distribution of Fedora 17 for x86_64 is named Fedora-17-x86_64-DVD.iso. Refer to Section 2.1.2, “Which Architecture Is My Computer?” if you are unsure of your computer's architecture.
  1. Full Distribution on DVD
    If you have plenty of time, a fast Internet connection, and wish a broader choice of software on the install media, download the full DVD version. Once burned to DVD, the media is bootable and includes an installation program. The DVD version contains a mode to perform rescue operations on your Fedora system in an emergency. You can download the DVD version directly from a mirror, or via BitTorrent.
  2. Live Image
    If you want to try Fedora before you install it on your computer, download the Live image version. If your computer supports booting from CD or USB, you can boot the operating system without making any changes to your hard disk. The Live image also provides an Install to Hard Disk desktop shortcut (alternatively, the shortcut can be found in Applications → System Tools). If you decide you like what you see, and want to install it, simply activate the selection to copy Fedora to your hard disk. You can download the Live image directly from a mirror, or using BitTorrent.
    For more detailed instructions on setting up a Live image installation, including selecting a language for the installation process, refer to the Fedora Installation Quick Start Guide.
  3. Minimal Boot Media
    If you have a fast Internet connection but do not want to download the entire distribution, you can download a small boot image. Fedora offers images for a minimal boot environment on CD. Once you boot your system with the minimal media, you can install Fedora directly over the Internet. Although this method still involves downloading a significant amount of data over the Internet, it is almost always much less than the size of the full distribution media. Once you have finished installation, you can add or remove software to your system as desired.

    Download Size

    Installing the default software for Fedora over the Internet requires more time than the Live image, but less time than the entire DVD distribution. Actual results depend on the software you select and network traffic conditions.
The following table explains where to find the desired files on a mirror site. Replace arch with the architecture of the computer being installed.
