Types Of Primary Memory
All the students should know the types of primary memory. Computer primary storage can be divided into three main types. That is the main memory that contains the instructions and data of the current program. Cache memory improves CPU performance by keeping a copy of instructions stored in the main memory to avoid unnecessary fetches. Registers the memory that contains the information required by the CPU’s arithmetic logic unit to execute instructions. Types of primary memory are asked many times in the exams. Cache memory and register memory are built into the CPU, but the main memory is a separate unit within the computer and is connected to the CPU by the data and memory buses. Primary storage saves the intermediate and final results of the process before saving it to persistent storage. The stored content is erased when the power is turned off, and some are non-volatile. Your program has a set of logically ordered instructions that you must use to process the data and produce results. Main memory can be divided into two main types, random access memory (RAM) and read-only memory (ROM), each of which is further subdivided. Frequently addressed instructions and data are stored in exclusive fast memory within the CPU to avoid wasting the effort and time of retrieving them from slow main memory. Registers as part of the CPU are used to hold the data during program execution, the next instruction, and the memory address of the intermediate result. Hope all the students have understood the types of primary memory.
