Here's a really simplified concept of the different parts of a typical desktop computer you might find in someone's house, organized in no real order:
input (mouse/keyboard)
output (monitor/speakers)
case (to house the hardware, to include a power button, etc)
processor (example: a 3.2GHz Intel Core 2 Duo "CPU")
memory (ram: i.e, 2GB of ram, a cache to keep info used in currently-happening tasks)
storage (a 320gb hard drive, a floppy/cd/dvd drive - something that has long-term data)
motherboard (mounted on the wall of the case, all hardware connects to this)
sound card (might be built-in to your motherboard, plug speakers into it for sound)
video card (might be built-in to your motherboard, plug monitor into it for visuals
power supply (gets power from wall outlet, precisely routes it to parts)
cooling system (might be a lot of fans in your case, maybe there is a liquid cooling, etc)
The components of computer which can be touched are called hardware component without hardware components computer are not useful.
When you purchase a computer with self assemble you just require MotherBoard , DVD Writter,PowerSupply,RAM,Harddisk.These are important component of computer.
Computer has two major components namely: Computer Hardware and Computer Software
Computer hardware is the components that make up a computer. Computer architecture is the model used to combine the Hardware into a working unit.
Hardware is something you can touch. So it is the physical components of the computer.

hardware and software
the three major hardware components of a computer are primary memory, secondary memory and object oriented programing.
A monitor is not normally considered hardware, the internal components of a computer are considered hardware.
Do you want a software to collect the computer‘s hardware information from LAN ?
A computer hardware engineer is involved in the design and development of systems and components. This would include hardware such as processors and circuit boards.
