Internal Hardware:- Hardware that is located inside your computer and may also be located in a computer is known as internal hardware.

Ex. Internal Hardware:-
1. Motherboard
2. Processor
3. Fan
4. Heat Sank
5. RAM
6. Rom
7. System Card
8. Sound Card
9. SMPS(Switched Mode Power)
10. Modem

1. Motherboard:- it really is called primary the main computer. It’s also called System Board.It may be the primary printed board which contain socket that accept power and talk to CPU and RAM.
2. Processor (CPU):-A processor handles all instruction that gets from software and hardware.
3. Fan:- an equipment unit that keeps the general computer or a computer unit cool by circulating atmosphere to or through the computer or component. The image is an example of a fan on a heat sink. Its on the top of the processor or CPU. That helps to pull bellow hot air of this processor and helping cooler.
4. Heat Sink:- a temperature sink is an electronic device that incorporates either a fan or a palter device to help keep a hot component such as for example a processor cool.
5. Network Card:- It is an expansion card that allows a pc for connecting to a network; such as for instance a true home system, or the world wide web using an Ethernet cable with an RJ-45 connector.
6. Sound Card:- A sound card is an expansion card or IC for producing noise on a pc that can be heard through speakers or headphones. Even though the computer doesn’t have a device that is sound function, they have been included on every device in a single form or another, either in an expansion slot or included in the motherboard (onboard).
7. SMPS(Switched Mode power):- A switched-mode power supply (SMPS) is an circuit that is electronic converts energy utilizing switching devices which are fired up and off at high frequencies, and storage components such as inductors or capacitors to produce power when the switching device is in its non-conduction state.
8. Modem:- A modem modulates outbound digital signals from a pc or other digital unit to analog signals for a regular copper twisted pair telephone line and demodulates the inbound analog signal and converts it to an electronic sign for the digital unit.
Outside Hardware:- Hardware that found outside the computer is recognized as Exterior Hardware.
