CS1 - Computer Systems - Microprocessor (CPU)

Microprocessor

Otherwise known as CPU. This is the heart of a computer, they are also found in all digital devices whether it’s a clock radio to a specialised system in cars.
There are 3 characteristics that a microprocessor has, these are:
Instruction set: this is the set of instructions that the CPU can perform.
Bandwidth: the number of bits processed after a single instruction.
Clock Speed: This is measured in megahertz (MHz), the clock speed defines how many instructions the processor can perform each second.

These characteristics is what usually determines which is better. Therefore a 64-bit CPU that runs at 50MHz will run better than a 32-bit CPU that runs at 25. 


It is advised not to remove the CPU due to the fragility of the CPU.
