WebThe CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. The CPU is constantly following instructions of computer programs that tell it which data to process and how to process it. Without a CPU, we could not run programs on a computer. WebMachine code has a much smaller range of things you can do, eg add 1 to 1, subtract 2 from memory spot x, turn on pixel x,y - it is the base set of instructions the cpu and computer components can do. The specific code is often cpu dependant as different cpus can understand/do different things.
