Live CDs

A LiveCD is a CD-ROM (or by extension a DVD-ROM or USB key) which allows a computer to boot from it directly. Live CDs generally leave the harddisk completely untouched, with the exception of using partitions marked as swap partitions. Live CDs typically run Linux or BSD and are substantially slower than running the same operating system and software from the harddisk. Work done when running a Live CD is typically lost when the computer is rebooted, unless the work is explicitly saved, across the network, to the harddisk or to a USB key.

Live CDs do typically use a swap partition if they find one on the harddrisk and thus run substantially faster. Swap partitions are "scratch pad" areas of the disk widely used in the linux and unix world.
