CPU

processors are the “BRAINS” of the PC, and generally it determines how fast the PC is. The CPU does DATA CRUNCHING in four steps: FETCHING, DECODING, EXECUTING and STORING. The speed of the CPU is measured in MHZ, and is calculated by multiplying the “FRONT SIDE BUS” by the “CLOCK MULTIPLIER”. MHZ is not the end of all CPU performance. CPU’s consume energy, and give off heat. Sometimes, the CPU gives off lots of it. Pieces of metal are attached to the CPU to pull heat away from the chip, fans are also mounted on these heat sinks to help blow the hot air away from the CPU. Thermal tape and Thermal grease also helps cool down the heat from the CPU.
