According to applicability
RAM (Random-access memory) is a type of computer memory that can be read and modified in any order and is usually used to store data working and car code. A RAM device allows data to be read or written in almost the same amount of time regardless of the physical location in the memory. The RAM memory is most often volatile, which means that when the electric current stops passing through it, all the information is deleted. Depending on the frequency, voltage, latency and other key specifications, currently DDR 3 RAM or DDR4 RAM memory is used.
Among the most important characteristics of RAM memory are storage space (eg 256 MB, 4 GB, 8 GB) and its speed (eg 1333 Mhz, 1600 Mhz, 2133 Mhz).
