It is a type of main memory, which is used by the computer to store data & programs temporarily during the times when they are needed in the Main memory.
The term “Random Access” means that, data in any area of the RAM can be reached or accessed in the same amount of time.
RAM provides “Read and write” facilities, i.e., it allow instructions to be written & read out, and also to be changed at will. Therefore, the computer user/ programmer can control or manipulate the data stored in RAM.
For example, it is this memory that is accessed during installation of programs; deleting, moving & copying of files.
Read refers to the retrieving (recovering) of information from memory, while Write refers to the storing of information in memory.
RAM is a Volatile memory, i.e. the contents of RAM are usually lost (rubbed off) when the power supply or the computer is switched off.
RAM forms the major proportion of Main storage – it contributes about 70% of the Internal memory. It is the memory used in large quantities in Main memory, and every computer must specify its size.
