Revison - The CPU
1 The purpose of the CPU is to Fetch Decode Execute, meaning it collects data, de-codes it so it understand than executes it onto an output device, for example: The moniotor
2 Clock Speeds
2.1 Clock speed is measured in Hertz ( Hz ) This is how many cycles the CPu is doing per second. The higher the clock speed, the faster the CPU runs
2.2 GigaHertz = 1000000000 cycles
2.3 MegaHertz = 1000000 cycles
2.4 KiloHertz = 1000
2.5 TerrorHertz = 1000000000000
3 Dual and Quad processors
3.1 Dual processors means that there's two CPU processors, meaning that the two 'brains' will work spontaneously ( At the same time ) Doing twice as much cycles, making the CPu faster
3.2 Quad processors means that there's 4, meaning it'll be doing 4 times as much cycles
4 Reasons for choosing higher or lower clock speeds
4.1 Higher
4.1.1 Advantage(s)
4.1.1.1 Faster performance
4.1.2 Disadvantage(s)
4.1.2.1 Runs hotter
4.1.2.2 Consumes more energy
4.2 Lower
4.2.1 Advantages
4.2.1.1 Less costly
4.2.1.2 Consumes less energy
4.2.1.3 Needs less power
4.2.2 Disadvantages
4.2.2.1 Slower performace
