Then the data is called from secondary memory to main memory and performs the execution of codes. If the processor does not need particular items for a longer time, the program or data is automatically saved into the permanent or secondary memory. For example, when we write and execute any computer program, it is initially stored in primary memory. We can retrieve it when the data is required. In the computer system, we need computer memory to store various types of data like text, images, video, audio, documents, etc. The address of the memory's cells varies from 0 to 65535. For example, if the size of computer memory is 64k words, the memory units have 64 * 1024 = 65536 locations or cells. Each cell has a unique address to store the data in memory, ranging from zero to memory size minus one. The memory block is split into a small number of components, called cells. It is the collection of storage units that stores binary information in the form of bits. What is computer memory?Ĭomputer memory is any physical device, used to store data, information or instruction temporarily or permanently. Also, we will discuss types of memory, features of memory, RAM, ROM, SRAM, DRAM, and its advantages and disadvantages. In this section, we have discussed the classification of memory in detail. The computer system categorizes the memory for different purposes and uses. In computers, memory is the most essential component of the normal functioning of any system.
