Detailed explanation-1: -Cache memory is the fastest system memory, required to keep up with the CPU as it fetches and executes instructions. The data most frequently used by the CPU is stored in cache memory.
Detailed explanation-2: -The registers are fast storage elements present in a very small amount in the computer processor. The recently used info/data of a computer gets stored in the cache. The data that the computer’s CPU is currently processing gets stored in the registers.
Detailed explanation-3: -The instruction read from memory is placed in the Instruction register (IR). The Temporary Register (TR) is used for holding the temporary data during the processing. The Input Registers (IR) holds the input characters given by the user. The Output Registers (OR) holds the output after processing the input data.
Detailed explanation-4: -In a computer, a register is the fastest memory. Register a part of the computer processor which is used to hold a computer instruction, perform mathematical operation as storage address, or any kind of data. The register memory indicates the capacity of the register to hold the size of data it can hold.
