CentOS Live CD
CentOS Live CD is an open source project that provides users with a multitude of ISO images designed from the ground up to be used by people who want to just test the CentOS operating system, without installing anything on their computers.
Availability and startup options
It is available for download as Live CDs, Live DVDs, a minimal CD for those who don’t have a fast Internet connection or smaller bandwidth plan, as well as a NetInstall CD ISO image that lets users to install the operating system over the network.
The Live CD and DVD ISO images come with the same boot prompt, which allows users to just boot the live environment with default settings on in text mode, run a memory diagnostic test, boot an existing OS, as well as to install the distribution without testing it (not recommended).
We strongly recommend to leave the boot medium to start on its own, after the timeout of ten seconds expires. If you accidentally press a key during that timeout and access the boot menu, make sure to choose the “Boot” option.
Traditional desktop environment with two panels
It presents a traditional desktop environment comprised of two panels, a top one for accessing the main menu and launching applications, and a bottom one for interacting with running programs and switching between virtual workspaces.
Default applications include the Mozilla Thunderbird email and news client, Mozilla Firefox web browser, TigerVNC VNC viewer, tsclient terminal server client, gThumb image viewer, gedit text editor, and Cheese webcam viewer.
In addition, CentOS Live CD features the Nautilus file manager, Disk Utility for managing hard disk drives and USB sticks, GNOME Terminal for running commands in a terminal emulator, as well as a character map utility.
Overall, CentOS Live CD is a great project, the only one that allows users to test this amazing Linux-based operating system without installing anything on their computers. It provides for a great alternative to the commercial Red Hat Enterprise Linux distribution.
