Primary and secondary storage: their differences, strengths and limitations. Computer Data Storage Computer data storage denotes computer components, computer devices and recording media that keep digital data used for computing, and we usually addressed it by storage or memory. It is one of the essential components of all modern computer that performs the basic computer model used together with a central processing unit (CPU). The amount and type of storage or memory that a computer owns has a great deal to do with its general applicability. In general, computer systems depend on two basic categories of storage, primary storage and secondary storage. It is named “primary” as it stores small amounts of data that will be promptly used by the CPU. On the other hand, the latter stores much larger amounts of information and data for much longer periods of time. Various different forms of storage or memory have been devised nowadays. Nevertheless, there is no functional universal storage medium exists still. We can notice that all forms of storage have some shortcomings and consequently a computer system often involves several kinds of storage that bring different purposes. Primary Storage Primary storage, also known as main storage or memory, is the main region in a computer. It stores three kinds of information for very short periods of time, which are data to be processed by the CPU, instructions for the CPU about how to process the data, and also operating system programs that handle many aspects of the computer’s operation. Primary storage occurs in chips positioned on the computer’s main circuit board, named the motherboard. Generally, there are four major types of primary storage, which are register, random access memory (RAM), cache memory and read-only memory (ROM). Register Register is part of the CPU that has the least capacity but it is high
