How Do You Know Types Of Computer Memory?
Computer memory refers to any device associate with or part of a computer that can store data or programs either temporarily or permanently. This information is represented in what is known as binary code, a sequence of 1’s and 0’s. Computer memory devices are made of integrated circuits with silicon-based transistors or capacitors. They basically work as switches with ‘on’ or ‘off’ states or positions which denotes the 1’s and 0’s of the binary code or store information as charges. There are generally two types of computer memory; one is called primary storage and the other is secondary. • Primary storage. Primary storage memory devices usually need to be powered with electricity in order to retain information. Thus they are also called volatile memory. Data stored in such devices can be retrieved at a constant time rate irregardless of where it is physically located. This form of storing data is known as random access memory (RAM). • RAM. RAM is further broken down into two categorie
