Computer Hardware – Computer Hardware Components

Computer Hardware:- It is best described as any physical component of a computer system that contains a circuit board, ICs, or other electronics. A perfect example of hardware is the screen on which you are viewing this page. Whether it be a computer monitor, tablet or Smartphone; it’s hardware.
Without any hardware, your computer would not exist, and software could not be used. The picture is a Logitech webcam, an example of an external hardware peripheral. This hardware device allows users to take videos or pictures and transmit them over the Internet.Types of Hardware:-HardwareInternal Hardware External HardwareInternal Hardware:- Hardware that is found inside your computer and may be found 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. Network Card
8. Sound Card
9. SMPS(Switched Mode Power Supply)
10. Modem1. Motherboard:- It is known as main part of the computer. It is also known as System Board.It is the main printed board which contain socket that accept power and communicate with CPU and RAM.
2. Processor (CPU):-A processor handles all instruction that receives from hardware and software.
3. Fan:- A hardware device that keeps the overall computer or a computer device cool by circulating air to or from the computer or component. The picture is an example of a fan on a heat sink. It is located on the top of the processor or CPU. That helps to pull bellow hot air of the processor and helping cooler.
4. Heat Sink:- A heat sink is an electronic device that incorporates either a fan or a palter device to keep a hot component such as a processor cool.
5. Network Card:- It is an expansion card that enables a computer to connect to a network; such as a home network, or the Internet using an Ethernet cable with an RJ-45 connector.
6. Sound Card:- A sound card is an expansion card or IC for producing sound on a computer that can be heard through speakers or headphones. Although the computer does not need a sound device to function, they are included on every machine in one form or another, either in an expansion slot or built into the motherboard (onboard).
7. SMPS(Switched Mode Power Supply):- A switched-mode power supply (SMPS) is an electronic circuit that converts power using switching devices that are turned on and off at high frequencies, and storage components such as inductors or capacitors to supply power when the switching device is in its non-conduction state.
8. Modem:- A modem modulates outgoing digital signals from a computer or other digital device to analog signals for a conventional copper twisted pair telephone line and demodulates the incoming analog signal and converts it to a digital signal for the digital device.
External Hardware:- Hardware that found outside of the computer is known as External Hardware.Ex. Of External Hardware.
1. Keyboard
2. Mouse
3. UPS
4. Microphone
5. Printer
6. Projector
7. Joystick
8. Speaker
9. Scanner
10. Projector

What is Computer Hardware – Understanding Computers and How They Work – Computer Hardware Components

If you are new to computers, you may have wondered what is computer hardware and how is it different from computer software? Put simply, the hardware is physical equipment, everything that allows the software to function. Aside from the cover components such as case and keyboard, the mouse, the program disks and books, hardware would include all “mechanical, magnetic, electronic and electrical components that make up your system”. (Ref: wordnet.princeton.edu/perl/webwn). Power supplies, floppy disks, digital video drives, flash drives, joysticks, cables, wires and audio components are considered to be “hardware” for computer use.Computer hardware includes all assorted devices that allow capturing and storage of data, that carry out operations or any series of operations on that data, or that produce control outputs. Computer software, on the other hand, is any of your computer’s self-contained or external programs and databases. Computers normally come pre-loaded with operational and some functional software when you purchase them.Within hardware, there is a lot of variety from which to choose. For example, keyboards can be standard, with or without accessory numeric keypads, they can be split or otherwise ergonomically designed. The mouse also has been modernized from a two click to a wheel style scroll button mouse. External accessory drives are available in many capacities and sizes. Flash drives are available with a range of storage capacity.What is computer hardware? It is anything you are able to see and touch (from the outside), and interior physical components like the motherboard or drive mechanisms. Software, although you may see and touch the actual disks data is contained on, is neither visible nor touchable. Compare it to your thoughts versus your brain.Easily visible hardware includes your central processing unit (CPU), speakers, monitor, mouse, screen, cords, and mouse pad. These make up the actual unit. Peripheral devices (hardware) would be your floppy disks, hard drive, floppy drive, CDs, CD drive, and random access memory (RAM) boards. Some of these are removable and/or can be shared and mailed. USB connectors, motherboards, routers and modems are also considered computer hardware.Computer hardware and software are highly developed and protected materials. Operating systems have evolved along with the computers to be used with ease by most operators. What used to fill entire buildings can now sit on your lap! Larger systems are created for commercial, business, and government use.There is one more situation to acknowledge, and that is the use of external hardware not located at your computer. This is where you have purchased, for example, a website from a host company, and you are using their equipment accessed remotely from your computer via the internet. You rent space on their computer, benefit from using their equipment, hardware and software far more expensive and intricate than you would have at home. It works well as needed, for website design, back up data storage, and off site data storage.So, the next time someone asks you “what is computer hardware”, you will be able to answer the question!
