When a person's short-term memory is filled, facts from the brain's long-term memory can be used to refresh it. Short-term memory is focused on the task at hand, but it can only hold a certain number of things in mind at any given time. A hard disk drive can be compared to a person's long-term memory, while RAM can be compared to a person's short-term memory. RAM can't store permanent data due to its volatility. If there is not sufficient RAM, then a computer will not be able to load and run the operating system quickly. The functionality and speed of the computer dramatically depend on the RAM. RAM is the fastest type of computer memory, hence it is the memory of choice for a computer’s internal memory. This random access makes RAM an expensive type of memory. This type of memory can be accessed directly without having to go through a sequence of memory locations. Volatile means the memory loses the data stored on it once the electricity is turned off. Even though non-volatile versions of RAM have been developed mostly commonly, the volatile version of the RAM is used. 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. New and updated hardware is being released to the public with more and more RAM to help users access more data at once while maintaining high speeds and efficiency.RAM (random-access memory) is a form of data storage that has been used in computers since the beginning of time.
Staying up to date with your business hardware needs goes hand-in-hand with having enough RAM to get the job done. It’s important that machines have enough RAM to function properly. Every device you use (desktop, laptop, tablet, smartphone, etc.) has RAM storage for the working processes within the machines. No programs, files, or video streams would work without RAM. A construction analogy is that RAM is your workbench workspace where all your work gets done while your hard drive represents your drawers and cabinets in which you store the tools (software) and materials (data) you need to work with and on. RAM complements your computer’s hard drive (SSD), which stores data long-term or permanently. RAM is fundamental to computer processing, being a super-fast and temporary data storage space that a computer needs to access right now or in the next few moments. Random Access Memory (RAM) is a machine’s short-term memory.
