What is computer hardware?

 Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), random access memory (RAM), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.

These are the 5 major components of a computer that you need to know about:

• Motherboard. ...

Motherboard parts

A motherboard (also called mainboard, main circuit board, MB,  backplane board, base board, system board; or in Apple computers logic board) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems, such as the central processor, the chipset's input/output and memory controllers, interface connectors, and other components integrated for general use.

• [2]Central processing unit (CPU):

The CPU, also called a central processor or main processor—is the most important processor in a given computer. Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. This role contrasts with that of external components, such as main memory and I/O circuitry,^[1] and specialized coprocessors such as graphics processing units (GPUs).

What is internal disk drive?

A tape, disk, optical or solid state drive that resides inside the case of a desktop or laptop computer. An internal drive derives power from the main power supply.
