"RAM (random access memory) is the most commonly recognized type of memory. It remembers, in a way, the programming and differing software on your computer.When RAM memory becomes full, the computer will move information to the virtual memory. Virtual memory is designed to be temporary, so you will need to either purchase more RAM or free up some space on your computer to avoid having your
. information lost. Another type of memory is ROM (read only memory). ROM kicks in whenever you restart or shut down your pc. At that point, any data you are working on is saved in ROM. From the ROM section of the computer's memory, the basic memory component BIOS does its job, and everything comes full circle again."
