Main Functions of Computer Memory

The major and the fundamental capacity of PC memory is to store every one of the information on the PC. Contingent upon the sort of information, aside from putting away information, it plays out some different capacities also. Every one of its capacities are identified with capacity just because of its essential part of putting away, similar to RAM, ROM, information stockpiling, hard drives and glimmer memory. Every one of them plays out its expected capacity to keep the PC working.

The capacities are as underneath.


Arbitrary access memory (RAM) gives the space to all the transitory application information stockpiling. At whatever point a PC needs a few information, rather than backpedaling and discovering data on the hard drive, it gets everything in the RAM as it stores all the regularly utilized applications. This turns out to be simple for the framework to locate the required data.

When we close down the PC, the framework eradicates or exchanges every one of the information of the RAM to the hard drive while making a space for the new information to get put away when the PC starts its activities once more.

— Hard Drive

A hard drive is the center of a PC’s information stockpiling. It supplies stockpiling for framework and client records that incorporate everything from your working framework to pictures and archives. In specialized terms, a hard drive is a turning plate that is treated with an attractive covering, like the attractive strips, which are utilized to store information on tapes. There is one moving arm that peruses and duplicates every one of the information and from the pivoting plate, it enables you to spare the new information or open records from the hard circle.

— Flash Memory

Streak memory is the normal term utilized for electronically-erasable-programmable-read-just memory (EEPROM). This is utilized as a part of computer game cards of the PC and furthermore to store some vital data of the framework. It isn’t cared for the other memory writes that eradicates or duplicates information byte-by-byte rather EEPROM is utilized to alter information in gatherings of bytes while making it a simple and an advantageous decision for the gadgets like memory sticks and cameras where the information put away changes much of the time every once in a while.


Read Only Memory is named as ROM. The information that is put away by ROM is utilized to control the most fundamental PC functionalities, for example, beginning up, working the PC fan and recognizing peripherals. What’s more, as the name proposes, the framework or the clients can’t alter this information. Everything recorded remains over yonder even in the wake of turning off the PC. Like the glimmer memory and hard drives, ROM is a case of non-unpredictable memory. Being non-unpredictable implies that the information remains set up notwithstanding when the power is off.
