On the DVD

CentOS 7 Release 1611 (64-bit Install)

CentOS derives from Red Hat Enterprise Linux (RHEL) and features a two-year release cycle, a six-month update cycle, and a 10-year security maintenance cycle, resulting in a "secure, low-maintenance, reliable, predictable, and reproducible Linux environment" [1]. Release 1611 now supports seventh-generation Core i3, i5, and i7 Intel processors and the I2C on sixth-generation Core processors. Other major changes include SHA2 support in OpenLDAP; Bluetooth LE; and updated storage, network, and graphics drivers. On booting the DVD, you have the choice of installing a minimal operating system, an environment with the Gnome or KDE Plasma desktop; a development and creative workstation; an infrastructure, web, or file and print server; a virtualization host; or a server with a GUI.

SystemRescueCd is a Linux system that boots to a command-line interface with tools for "administrating or repairing your system and data after a crash" [4].
