What is the main function of a RAM?

Answer 1

RAM stands for Random Access Memory. It is temporary storage for data. For instance, when you open Microsoft Word (or any program), it goes into RAM because your CPU can get it a lot faster from RAM, than if it tried to get it off of your hard drive. However, RAM is dynamic which means if the power is cut off then any data that is in RAM is lost. Lets say you are typing a letter, each time you hit the keyboard that data is put into RAM until it can be transferred to your hard drive. If the power goes off then whatever is in RAM while you were typing will be lost.

Answer 2

Random access memory (RAM) is temporary memory your computer uses to store things you are working on for quick access. The more RAM you have, the more programs you can have running at the same time, and the less the operating system has to rely on swap files and temporary files.

RAM is also used on video adapters. The reason for this is that the memory will be faster on the board than it will be to access the RAM on the motherboard, since that would require crossing the peripheral bus. Video card RAM allows it to store textures, rather than accessing them through system RAM or retrieving them from the hard drive again. Plus the more RAM a video card has, the higher the resolution it is capable of displaying to a point, and the more completed screens it can store.

Answer 3

It is for storage of data in a computer which can be retrieved later for use.ROM stores data permanently while RAM stores data temporarily.

Answer 4

RAM... is fast-access memory, where the computer stores information temporarily, while processing data.
