Some people think that CPU and processor are just two different terms that are used for the same thing. But this is not the case!

The processor is a component of the central processing unit (CPU). A CPU can have multiple processors.

It's easy to mix the two. A processor must have memory, ALU, and I/O interfaces. People often confuse the two because processors now list them all in their specifications and design. When computers first appeared on the scene, processors contained very few functional units.

CPU is the main part of the computer. Without the CPU, the computer cannot work.
Five Components Of Computer System

The five main components that make up a modern standard computer are:


CPU (central processing unit)

GPU (Graphics processing unit)

RAM (random access memory) or volatile memory

Storage (Solid State Drive (SSD) or Hard Disk Drive (HDD))

In terms of installation, each of these major components plugs into the motherboard before it is encased in a cover, giving it the clean and shiny look you see.
