You can liken it to the rough paper used for doing mathematical calculations, while the hard drive is the “fair” page where the finished work is stored once the calculations are completed. Various computations can be stored here, and items from the hard drive are loaded into RAM memory for easy access by the CPU of the computer system. It functions as the primary memory of a computer system.

RAM is the internal memory of a computer. RAM memory has plenty of features that need to be perused for a thorough understanding of this subject. If you want, you can erase what was written and write again. RAM can be likened to a slate or a whiteboard where one can write as well as read. RAM is volatile, which means that the contents of memory can be erased when electricity is removed from it. It is a memory device that is located on the motherboard of a computer and is used as the area of memory where the computer temporarily stores its work. The full form of RAM is random access memory. In this article, details of “short term memory” or RAM will be discussed. Preferably, the short term memory should be a fast-access memory to save time. And it requires short term memory so that the computer can quickly recall what instructions were given moments ago or what calculations it was performing. It needs long term memory to retain information even after the electricity is removed from it, so it acts like a memory store. 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.
