components of a pc

A pc comprises of hardware and software. Everything that you can see and touh in the pc is called the hardware. the computer has a large number of components. Each of these parts is essential to the functioning of the pc. The input devices, output devices, storage devices, processing devices, communication devices and infrastructure are the different parts of the pc.

Input Devices:
Keyboard, Mouse, Scanner

Output Devices:

Display card -

Display card used to support visual effects on a pc. The Display card takes the data from different parts of the computer and takes it to the monitor in a format that the monitor can use.
Modern display cards are very advanced and can store images as well this reduces the burden on the CPU.

Sound card -

Used to generate sound effects in a computer.

Monitor and Printer also output devices

Storage Devices:
Storage Devices are used to store data in the computers. There are several types of storage devices for computer.
Floppy Disk, Hard Disk, CD, DVD, Pendrive etc.. these are all storage Devices.

Processing Devices:
main function of a computer is to process data. Central Processing Unit ( CPU ) is the processing device of the computer. Data that the user inputs is processed by the CPU.
Various types of processing devices are as follows.

Microprocessors - Controls the flow of data in the system. The most important electronics component on the Mother Board is the microprocessor. The power of a computer how fast it can accomplish a given job, Such as resizing a digital photo depends on the model of microprocessor in the computer as well as how fast the microprocessor operates.

Chipset -
Provides vital support functions to its microprocessor. The chipset creates signals such as clocks or oscillator that sets the pace of logic operations of the microprocessor. In addition, it links the microprocessor to the rest of the computer, both the memory and external functions, through I/O ports.

BIOS -
Instructs the computer what to do before loadig any software. This program is called the Basic Input Output System ( BIOS ). It is mounted in the ROM of the comjputer.

Communication Devices:

Serial port - Connects to devices such as modems, mice, and digital cameras. Serial ports are the oldest kinds of ports in use. They transmit data in a serial fashion. Serial ports enable data flow in both directions.

Parallel port -
Connects to scanners, CD burners, hard drives and printers, parallel ports are much faster than serial ports. These ports transmit data in a parallel mammer. parallel ports are wide in size to enable parallel transmission of data.

USB ( Universal Serial Bus ) -
Connects to a wide range of devices like mouse, keyboard, modems and speakers. USB is a becoming a popular replacement for serial and parallel ports. This is because USB is highly adanced, fast and simple to use.

LAN card -

LAN card connects the pc to a network. The LAN card enables connections to other computers. We exchange data and resources across a network. The LAN card is crucial to this objective. Companies can share devices like printers across a network and access data in an intranet.
