The main and basic function of the computer memory is to store all the data in the computer. Depending on the type of data, in addition to storing data, it also performs other functions. All of its features are related to storage only because of its primary function of storage such as RAM, ROM, data storage, hard drives, and flash memory. Each of them performs its required function to keep the computer running.
The functions are as follows.
-RAM
Random Access Memory (RAM) provides the space for all temporary application data storage. Whenever a computer needs some data, instead of going back and finding information on the hard drive, it gets it all in RAM as it stores all frequently used applications. This makes it easier for the system to find the required information.
When we turn off the computer, the system erases or transfers all data from RAM to the hard drive while making room for the new data to be stored when the computer starts running again.
-HDD
A hard drive is the core of a computer’s data storage. It provides storage for system and user files that include everything from your operating system to images and documents. In technical terms, a hard drive is a spinning disk treated with a magnetic layer, similar to magnetic tape, used to store data on cassettes. There is a movable arm that reads and copies all the data and from the spinning disk, it allows you to save the new data or open files from the hard drive.
-Flash memory
Flash memory is the common term used for electronically erasable programmable read-only memory (EEPROM). This is used in computer game cards and also to store important system information. Not like other types of memory that erase or copy data byte-by-byte, instead EEPROM is used to edit data in groups of bytes, making it an easy and convenient option for devices like memory cards and cameras where stored data changes frequently from time to time.
-ROM
Read-only memory is called ROM. The data that the ROM stores is used to control the most basic functionalities of the computer, such as startup, the operation of the computer’s fan, and the detection of peripherals. And, as the name suggests, this data cannot be edited by the system or users. Everything recorded stays there even after turning off the computer. Like flash memory and hard drives, ROM is an example of non-volatile memory. Being non-volatile means that the data stays in place even when power is removed.
