Random-access memory

RAM

• Random-access memory  is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media (such as hard disks, CD-RWs, DVD-RWs and the older magnetic tapes and drum memory), where the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement.

It comes in two forms:

• RAM happens: DDR, DDR2, DDR3, DDR4 and DDR5/

• It also comes in different frequencies. For example, DDR3 memory may have a frequency of 1333 MHz. And DDR4 3200 MHz. It all depends on novelty.
