Type of Hardware Parts of Computer

A Computer consists of a set electromechanical component able to accept some form of input, process this input in a way that we can specify, and produce some form of output. Hardware Parts of Computer refers to the all of physicals parts of computer like circuits, computer chips, graphic cards, sound cards, memory (RAM), motherboard, displays, power supplies, cables, keyboards, printers and "mice" input devices.

Here are given Some Hardware Component

Input devices

The input devices may be hand-operated or automated. When unprocessed data is sent to the computer with the help of input devices, the data is processed and sent to output devices. Some example of input devices is

• Computer keyboard
• Digital camera
• Digital video
• Graphics tablets
• Image scanner
• Joystick
• Microphone
• Mouse
• Overlay Keyboard
• Real-time clock
• Trackball
• Touchscreen

Output Devices

That through Computer gives output that are called output devices. Here are given some examples

• Computer monitor
• Printer
• PC speaker
•  Projector
• Sound Card
• Video Card

Control Unit

CPU or Processors perform computations. They do math for your calculator application. In shorts, it manages the computer’s various components, it reads and interprets the program instructions, transforming them into control signals that activate other parts of the computer. It is also called a control system or central controller.

Arithmetic Logic Unit (ALU)

The ALU is capable of performing two classes of operations: arithmetic and logic. The set of arithmetic operations that a particular ALU supports may be limited to addition and subtraction, or might include multiplication, division, trigonometry functions such as sine, cosine, etc., and square root.

Memory

A Computer’s memory can be viewed as a list of cells into which numbers can be placed or read. Memory is what allows a computer to remember things. Similar to human memory. When Computer is turned off, it forgets everything in the RAM, so the computers saves everything it knows it will need later on in the long-term memory.

Computer memory comes in two types:

• Random-access memory or RAM
• Read-only memory or ROM

Ram Can be read and written to anytime the CPU commands it, but ROM is preloaded with data and software that never changes; therefore, the CPU can only read from it. ROM is typically used to store the computer’s initial start-up instructions.

Input/ Output (I/O)

I/O means by which a computer exchanges information with the outside world. The amount of I/O a computer has can be changed, by adding expansion cards that support I/O. A graphics card can be added to a computer to let it talk with a display, or a WIFI card can be added, which will let a computer talk to other computers without a connecting wire. Hard disk drives, floppy disk drives and optical disc drives serve as both I/O devices. Computer networking is another form of Input/ Output

Motherboard               

The motherboard is a computer part of hardware that makes connections in the right places between all of the other components in a computer. It tells data where it should go. When the CPU is finished processing some data, it might say to the CPU, OK, put this in the HDD, and the motherboard will figure out where the HDD is and send the data there.

Multiprocessing

Some computers are designed to distribute their work across several CPUs in a multiprocessing configuration, a technique once employed only in large and powerful machines such as supercomputers, mainframe computers and servers. Multiprocessor and multi-core personal and laptop computers are now widely available, and are being increasingly used in lower-end markets as a result.
