Attributes of Computer








A computer is a gadget that can get procedure and store information.

Be that as it may, all computers share a few sections practically speaking:

Information gadgets enable information and directions to the computer (Mouse, Keyboard and so on.)

Memory for putting away directions and information.

Focal Processing Unit which controls the preparing.

Screen Process the data as yield.

Types of Computer

Computers extend in size and ability. There are supercomputers, huge computers with a huge number of microchips that perform incredibly complex computations.

Image result for computer

There are small computers installed in autos, TVs, sound systems, mini-computers, and machines. These computers are worked to play out a couple of number of undertakings.

Desktop Computers

Work stations configuration is made for use at a work area or table.

They are regularly bigger and more dominant than different kinds of PCs.

The fundamental segment, called the framework unit, is normally a rectangular case that sits on or underneath a work area.

Different segments, for example, the screen, mouse, and console, associate with the framework unit.


The Laptops are lightweight versatile PCs with a slight screen.

PCs can work on batteries, so you can take them anyplace.

In contrast to work areas, workstations join the CPU, screen, and console in a solitary case.

The screen overlays down onto the console when not being used

Handheld computers (PDA)

Handheld computers, otherwise called individual advanced colleagues (PDAs), are battery-control computers little enough to convey anyplace.

These are helpful for booking arrangements, putting away locations and telephone numbers, and making diversions.

Some have propelled abilities, for example, making phone calls or getting to the Internet.

Rather than consoles, handheld computers have contact screens that you use with your finger.

Peripheral Devices

The fringe gadget interfaces with a computer framework to include usefulness. Precedents are a mouse, console, screen, printer and scanner.

A computer fringe is a gadget that interfaces with a computer yet isn’t a piece of the center computer design.

The center components of a computer are the focal handling unit, control supply, motherboard and the computer case that contains those three parts.

Types of Peripheral Devices

There are numerous fringe gadgets, yet they fall into three general classifications:

Info gadgets, for example, a mouse and a console

Yield gadgets, for example, a screen and a printer

Capacity gadgets, for example, a hard drive or blaze drive

Hardware of Computer

Computer equipment is the thing that you can physically contact incorporates the computer case, screen, console, and mouse.

It additionally incorporates every one of the parts inside the computer case, for example, the hard plate drive, motherboard, video card, and numerous others.

Input Devices

In figuring, an information gadget is a fringe (bit of pc equipment gear) used to give information and control sign to a data preparing framework.

It will control gadgets, for example, a pc or data machine.

Precedents: consoles, mice, scanners, advanced cameras and joysticks.

Keyboard of Computer

A Keyboard is the most basic information gadget for any pc framework.

It enters information on the pc.


A mouse is utilized to enter information by sending a sign to the computer, in view of floating the cursor and choosing with the left mouse catch.

Barcode Reader

A standardized tag peruser (or scanner tag scanner) is an electronic gadget that can peruse and yield printed standardized identifications to a pc.

Like a flatbed scanner, it comprises of a light source, a focal point and a light sensor making an interpretation of optical motivations into electrical ones.

Digital Camera
