Full Concept of RAM (Random Access Memory).

Random Access Memory or volatile memory, is used by a system to store data for processing by a computer’s central processing unit (CPU), also known as the processor. RAM stores the data in memory cells that are arranged in grids much like the cells that are arranged in a spreadsheet, from which data, in the binary form of 1’s and 0’s, can be accessed and transferred at random to the processor for processing by the system’s software.

When the computer is turned off, all of the data in the RAM memory is lost, hence its alternative name of volatile memory, whereas all of the data on a hand disk drive is retained permanently until it is intentionally erased. The motherboard (or main board) manual (that should be provided with a new or second-hand PC) will provide all of the details about the different types of supported RAM and the various combinations of modules per bank for each type that cab successfully installed.

Ram can be divided into different types, but in general there are three types of RAM (Random Access Memory).

  • SRAM (Static Random Access Memory).
  • DRAM (Dynamic Random Access Memory).
  • SDRAM (Synchronous Dynamic Random Access Memory).
