How RAM Work on a Computer

RAM (Random Access Memory) is a type of computer memory that is used to temporarily store data that is currently being used by the computer's CPU (Central Processing Unit). RAM provides fast read and write access to this data, which is critical for the computer's performance.

When you open a program or file on your computer, the CPU retrieves the data from the hard drive and stores it in RAM. This data can then be quickly accessed by the CPU as it performs calculations and operations. Once the program or file is closed, the data is no longer needed and is removed from RAM to make room for other data.

RAM is volatile memory, which means that it requires a constant supply of power to maintain its contents. When the computer is turned off, the data stored in RAM is lost. This is why it is important to save your work to a non-volatile storage device such as a hard drive or SSD (Solid State Drive).

Modern computers typically have several gigabytes (GB) of RAM, which allows them to run multiple programs and perform complex tasks simultaneously without slowing down. The amount of RAM required for a specific task depends on the nature and size of the data being processed.
