The CPU

The CPU is the brain of everyday electronics. The microprocessor is a CPU that is small enough to fit in iPods and is the one used today, unlike the past when the CPU was large, almost bigger than a fridge! They weren’t as small as the ones today with very the small parts in the technology humans use today. The CPU has come a long way in its history with its components and types.

The microprocessor all started with the Intel 4004 in 1971. The CPU (Central Processing Unit, also known as the microprocessor) is a very complex part of computers that has many complicated parts, a compound evolution, and different architectures for every deveice (Davis).

Arithmetic unit, logic unit, and registers make up the complicated CPU (Garza). The arithmetic unit is the digital circuit that performs integer arithmetic (things to do with numbers and math) and logical operations (Wikipedia contributors Flip). Now lastly, the registers. These are simple parts in the CPU that help hold data to process. Otherwise the CPU wouldn't work as it needs somewhere to place it’s instructions (What is CPU?).

CPU box labeling is key to giving customers the information they need for their next CPU. For instance, the clock rate the CPU processes at. This is the maximum speed the CPU can process instructions. This is measured in hertz, or more or less, gigahertz. Gigahertz are the equivalent of one billion hertz. A hertz is one second. So if the average clock rate in a CPU is 1.5 GHz the CPU would process one billion five hundred million instructions per second. Now all these instructions are processed one by one, individually. In other words, the CPU has to process an instruction to get to the next (Wikipedia contributors Central).
