What is a RAM in computer?

Ram means Random Access Memory. It is a short-term memory, much like the brain of a human, which stores information. RAM is known as volatile memory because if the computer loses power, all the RAM data will be lost. Non-volatile memory is a memory that keeps its data while the system isn't running. The RAM is accessible through the computer's brain called the CPU, which stands for the Central Processing Unit. 

 

The RAM is the memory being used when the computer system is ON. When the computer is turned off, the RAM is no longer accessible. Today's computer comes with at least 512MB RAM size. Additional RAM can be placed within the system, but there is usually a limitation placed upon just how much RAM can be added to a computer system.  

Some of the commonly used RAM today is

• Static RAM (SRAM)
• Dynamic RAM (DRAM)
• Synchronous Dynamic RAM (SDRAM) and so on.
