Computer Hardware Terms, Glossary and Dictionary

Main memory, also known as RAM (Radom Access Memory), refers to the internal physical memory of CPU. Computers use RAM to hold the program code and data during execution. One defining characteristic of RAM is that its accesses to different memory locations are almost always completed at about the same speed, in contrast to some other technologies that require a certain delay time for a bit or byte to “come around”.
