The major & the basic function of computer memory is to store all the data on the computer. Depending on the type of data, apart from storing data, it performs some other functions as well. All its functions are related to storage only due to its primary role of storing, like RAM, ROM, data storage, hard drives & flash memory. Each of them performs its required function to keep the computer working. The functions are as below. RAM Random access memory (RAM) provides the space for all the temporary application data storage.
Whenever a computer needs some data, instead of going back & finding information on the hard drive, it gets it all in the RAM as it stores all the frequently used applications. This becomes easy for the system to find the required information. When we shut down the computer, the system erases or transfers all the data of the RAM to the hard drive while making a room for the new data to get stored when the computer begins its operations again. Hard Drive A hard drive is the core of a computer’s data storage. It supplies storage for system & user files that include everything from your operating system to images & documents. In technical terms, a hard drive is a rotating disk that is treated with a magnetic coating, similar to the magnetic ribbons, which are used to store data on cassettes.
