If your older system still runs, has WiFi, 1 GB memory and

Ubuntu 14.04 (released 4/18/14) was chosen for the laptop to support the Belkin USB wifi N. CentOS6 was chosen for the Tower for RHEL simulation. What is the difference?
Usually support for hardware, desktop display, package software handling, and the version of linux kernel. The root for Ubuntu is Debian and the root for CentOS is RHEL, hence Ubuntu is based on Debian's package manage based on APT and DPKG. Red Hat, CentOS and Fedora are based on the old Red Hat Linux package management system, RPM.

No matter the flavor of linux 90% of the commands are the same. Different for package.
Ls = list files in directory, mkdir = make directory/folder, for every graphic, behind the curtain is a command line or multiple sets of code actually doing the work. Ie. a package may require other code to be loaded as it checks for dependencies.
