The Main Functions of Computer Memory

The major and the fundamental function of computer memory is to store the information on the PC. Depending upon the kind of data, apart from storing documents, it executes some functions as well. All its functions are associated to storing only due to its main role of storing, RAM, ROM, data storage, hard drives and flash memory. Every one of them plays out its required function to keep the PC working.

The functions are as below.

RAM

Random access memory (RAM) gives the space for all the temporary application data storage. At whatever point a PC needs a few data, rather than going back and discovering data on the hard drive, it gets everything in the RAM as it stores all the frequently used applications. This turns out to be simple for the system to find the required data.

When we turn off the PC, the system erases or exchanges every one of the information of the RAM to the hard drive while creating a space for the new data to get stored when the PC starts its activities once more.

Hard Drive

A hard drive is the center of a PC's data storage. It supplies storage for system and user files that incorporate everything from your operating system to pictures and documents. In technical terms, a hard drive is a revolving disk that is treated with a magnetic coating, like to the magnetic ribbons, which are utilized to stock data on cassettes. There is one moving arm that peruses and duplicates every data and from the rotating disk, it enables you to spare the new data or open documents from the hard disk.

Flash Memory

Flash memory is the basic term utilized for electronically-erasable-programmable-read-only memory (EEPROM). This is utilized as a part of video game cards of the PC and furthermore to store some vital data of the system. It isn't like the other memory types that erases or duplicates data byte-by-byte rather EEPROM is utilized to alter information in groups of bytes while making it a simple and a convenient choice for the gadgets like memory sticks and cameras where the data stored changes frequently from time-to-time.

ROM

Read Only Memory is named as ROM. The information that is stored by ROM is utilized to switch the most essential PC functionalities, for example, beginning up, working the PC fan and distinguishing peripherals. What's more, as the name proposes, the system or the clients can't alter this information. Everything recorded remains over there even after turning off the PC. Like the flash memory and hard drives, ROM is a case of non-volatile memory. Being non-volatile implies that the data stays in place even when the power is off.
