Cache Memory
*A small high speed memory which is used to store a portion of a program or data temporarily from the main memory.
*Processor retrieves instructions or data from the cache memory.
*Cache memory acts between - CPU & RAM Register
Register
*Serially interconnected group of highspeed memory cells inside the CPU is called - Register
*All data must be represented in a register before it is processed.
*Number of registers a CPU has, and the size of each helps to determine the power and speed of a CPU.
*Part of CPU which supply operands to ALU - Register
*Part of CPU which store result of ALU operations - Register
Buffer
*Buffer is a storage area in RAM, where data is stored for a short amount of time.
*The purpose of a buffer is to hold data right before it is used
Address
