A central processing unit (CPU), also called a central processor, main processor, or just processor, is the most important processor in a given computer. [1] [2] Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations.
In computing and computer science, a processor or processing unit is an electrical component (digital circuit) that performs operations on an external data source, usually memory or some other data stream. [1]

PDP-11 CPU board. Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. [1] [2]
The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).
In a clockless CPU, components can run at different speeds. In a clocked CPU, the clock can go no faster than the worst-case performance of the slowest stage. In a clockless CPU, when a stage finishes faster than normal, the next stage can immediately take the results rather than waiting for the next clock tick.
Apple M1 system on a chip A system on a chip from Broadcom in a Raspberry Pi. A system on a chip or system-on-chip (SoC / ˌ ˈ ɛ s oʊ s iː /; pl. SoCs / ˌ ˈ ɛ s oʊ s iː z /) is an integrated circuit that integrates most or all components of a computer or electronic system.
In a hotly-contested marketplace AMD and others released new versions of multi-core CPU's, AMD's SMP enabled Athlon MP CPU's from the AthlonXP line in 2001, Sun released the Niagara and Niagara 2 with eight-cores, AMD's Athlon X2 was released in June 2007. The companies were engaged in a never-ending race for speed, indeed more demanding ...
