CPU Definition

CPU also known as Central Processing Unit is the core and most vital processing system in any particular computer controlling and giving instructions to every computer program acting as a sort of “brain” for the computer. These include input and output operations, algorithmic calculations, logic, and much more.

To describe in simple terms what exactly a CPU is responsible for you can look at it from three perspectives: it stores and retrieves instructions from the memory, decodes instructions from the Instruction Register, and executes the decoded data based on related destinations. Overall the CPU’s location is at the motherboard of a computer.
