What is computer memory (RAM)?
Generally referred to as just “memory,” random-access memory (RAM) is the part of the computer that stores all the information an operating system (like Windows® or Ubuntu) needs while it runs. “Random-access memory” refers to the type of data storage that allows stored data to be accessed in any order — that is, at random, not just in sequence. In contrast, other types of memory devices (such as magnetic tapes, disks, and drums) can access data on the storage medium only in a predetermined order due to constraints in their mechanical design. In general terms, random-access memory is like a music CD, allowing you to jump to any song as desired. Whereas a cassette tape must be forwarded (or reversed) to the desired song and takes considerably longer to do.
