The primary role of computer memory is to store all data on the computer. Depending on the type of data, the memory performs other functions as well. Whereas some people may not be interested in computers or IT, it is essential to understand some of the vital functions of computer memory.Nowadays, most employers need individuals who are tech savvy. Below are some of the functions.
Primary functions of a computer memory
RAM is the acronym for random access memory. It is used to provide storage for temporary data. This means that whenever the computer needs some data, instead of going to the computer’s hard drive to collect the data, it will get the information from its RAM. This is because the RAM stores the applications that are frequently used. This makes it easier for the computer to access the information. When the machine is switched off, the data is moved to the hard drive to create room for new data.
This is the core of a computer’s storage of data. It stores all data in the computer from the operating system, documents, and images. The hard drive is the disk that has a magnetic coating. It operates efficiently by having one arm that moves as it reads and copies all data from the rotating disk. This allows individuals to save and open new data from the hard drive.
This is the acronym for read-only memory. Data that is saved here is used to control the basic functions of the computer like starting up the computer, detecting peripherals and turning on the computer fan among others. The system or individuals cannot edit this data. Even after switching off the computer, the information is not moved to any other storage. Therefore, ROM is an example of a non-volatile storage which simply means that the data stays in place even when the system is off.
Flash memory is a term for electronically-erasable-programmable-read-only- memory (EEPROM). It is used for essential programs of the system as well as the video game cards of the computer. Unlike other memories which are used to erase and copy data byte by byte, EEPROM is used to edit data in groups of bytes, therefore, making it easy to use. It is also convenient for other devices like cameras and memory sticks. This is because data stored in these devices change from time to time.…
