A CPU cache is a hardware cache used by the central processing unit of a computer to reduce the average cost (time or energy) to access data from the main memory.
In computer hardware, a CPU socket or CPU slot contains one or more mechanical components providing mechanical and electrical connections between a microprocessor and a printed circuit board.
In computing, the clock multiplier (or CPU multiplier or bus/core ratio) sets the ratio of an internal CPU clock rate to the externally supplied clock.
