The overall speed of your system is largely determined by the speed of your CPU and the amount of RAM in your system. The speed of a CPU is measured in gigahertz (GHz), billions of instructions per second, or for older (and slower) systems in megahertz (MHz), millions of instructions per second.

The amount of RAM determines how much data the CPU can ...
