RAM is a short-term temporary form memory, as the memory is lost when the computer is turned off. RAM can also automatically be overwritten by computer programs that require the space.
RAM stands for "random access memory." It is used by computer programs to temporarily store computer code and data that they need in order to run. Having more RAM means that a computer is able to run more programs simultaneously and run them faster. ROM, or read only memory, is a computer's long-term memory and is used to store data even after the computer is turned off. An example of ROM is a computer's hard drive, which is where most people choose to save documents, pictures, music and more.
