Question: Describe three major components of computer hardware?

Computer hardware refers to the physical devices that make up a computer system. Three major components of computer hardware are the central processing unit (CPU), the random access memory (RAM), and the hard disk drive (HDD).

The CPU is the brain of the computer, responsible for executing instructions and performing calculations. The CPU consists of a control unit, an arithmetic logic unit, and a set of registers.

The RAM is the short-term memory of the computer, where data and programs are stored temporarily while they are being used. The RAM is volatile, meaning that it loses its contents when the power is turned off.

The HDD is the long-term memory of the computer, where data and programs are stored permanently. The HDD is non-volatile, meaning that it retains its contents even when the power is turned off. The HDD consists of one or more spinning disks coated with magnetic material, and a read/write head that accesses the data.
