![]() It requires both “long term memory” as well as “short term memory”. To store all this information and keep it secure, a computer requires some “memory”. Thus, a computer needs on hand a rough sheet of paper where it can store the in-between details of those computations it is presently working on. However, a computer needs someplace where it can store temporary results, program instructions, and perform interim calculations. Now, it is of practical importance to human beings to get a computer to “remember” certain things for a longer period. It computes data, stores and retrieves information as well as sends out input and output signals to various input and output devices. A computer is quite similar to the human brain. This article focuses on how RAM works, what it does, and the many types of RAM available today, such as Dynamic RAM (DRAM) and Static RAM (SRAM).īefore plunging into an explanation of what RAM is, it needs to impress on the reader’s mind the importance of having fast-access memory in a computer system. It serves as the main memory for computer systems, making it simple to find specific information fast. RAM (random-access memory) is a form of data storage that has been used in computers since the beginning of time.
