Fundamentals of Computer

What is the definition of a computer?

People always do the question, what is the definition of a computer? Who does not know helter-skelter computers, we talk nearly it in our daily alive. Before the arrival of computers, we humans had a number of impediments in calculating numbers. Also, all such works cannot be done even if you destitution to, but they can be done in a second or minute with the application of computers.

Let’s break the speech Computer into the Function as below.


C = Compute

O = Organized

M = Memory

P = Print

U = Update

T = Table

E = Edit

R = Respond or Result.

By the way, the computer’s meaning proceeds from the Latin word “computare”, which signifies “to calculate”, “to rely on”, “to sum up” or “to think together”. To count, Therefore, in easy language, a computer can be considered as a design that performs computation. Let us recognize the delimitation of a computer.

The definition of a data processor is as uncombined as that. An electronic computer is a machine or machine that performs processes, calculations, and operations, based on instructions, done by a software or ironmongery notice.

It has been designate so that it can make applications and provide a variety of solutions, for this it business by agree mixed hardware and software components.

An information processing system is made up of manifold parts and components that ease user functionality.

There are two first categories of a computer:

  1. Hardware: Physical building that trusts the processor of your data processor, memory, storage, communication ports, and peripheral device devices.
  2. Software: This includes the at work(predicate) system (OS) and software applications.

Computer manufacture with software playbill that is sent to its fundamental ironmongery architecture so that it can read, interpret, and consummate.

Computers are categorized by their figure sway, character, size, mobility, and another constituent Like Personal Computer, Desktop Computer, Laptop Computer, Mini Computer, Handheld Computer and Devices, Mainframes Computers and Super Computer.

Technically, a data processor is a programmable machine. This means that it executes a scheme hearken of instructions and at the same time it also rejoins to the new instructions which are stated to it.

Nowadays this term is a habit only to refer only to a desktop or laptop computer.

When we send to a desktop model, the term “data processor” technically refers only to the data processor – not monitor, electronic keyboard, or mouse, but this is absolutely pleasant when we refer to all one together as the computer.

If you consider plentifully technical, then the spar which holds the computer is called “system unit”.

Features of Computer

A computer has properties and shapes that distinguish it from other devices. Let’s know helter-skelter it in a larger way.


As we know that computer employment very steadfast. It only captivates a few seconds to do any calculations, which we may take longer than that for several hours.

You will be surprised to know that the computer can process instructions of about 1 million (1,000,000) in an aid or even more.

Therefore, the speed of the data processor is possessed in a microsecond (10 ^ 6 part of a subordinate) or nanosecond (10 ^ 9 part of a help). From this, you can contemplate how steadfast are these computers and how do they perform.


The degree of propriety of the computer is very high and each calculation is executed with the same truthfulness. The accuracy level is set supported on the design of the information processing system.

Whatever errors are there in the electronic computer, due to our imperfection as we are for humans or if we have entered imperfect data.


An electronic computer is completely immune, it does not have human emotions like tiredness, lack of major, fatigue. It is only a machine. This can work for extended hours without any irregularity.

Even if calculations are performed in a numeral of millions, still an information processing system will perform all calculations with even nicety.

Due to its capability, it helps us in doing the groove example of manufacture.


This indicates that it can embroidery in different works in the same tense. Just probable you are charged payroll slips from your computer at the same era, in the same away you are paying an electric bill.

Ability to Store the data

In computers, it can storehouse the amount of message or data. Any notice can be restored or recall whenever we want. It can be stored safely for many years.

It depends on the user above how much data he wants to store and when he wants to restore it.

Lack of IQ

A computer is fully a dumb bicycle and cannot do any work by itself, it has to be instructed to do each task.

And it performs its fabric with speed and precision as soon as it is directed. It depends on you what you want to do on your computer.

It does not have the Feelings

It has no feelings or emotion, gout, scholarship, or suffer of itself. You may get tired after working for some time, but the computer never obstruct.


The computer has its own in-built reminiscence where it can accumulation a populous amount of data. With this, you can also store your data in all secondary storage devices if you deficiency. It is stored outside the electronic computer and can also be stored on the salver.

Main Types of Computer Software

1. Operating System Software

2. Application Software

3. Programming Software

4. Utility Software

Operating Software

It is the most essential software used in computers. Because through this the entire computer is assigned and the information processing system works to work them.

There are mainly two types of operant system software.

  • Single User Operating Software: This is a mean operating system; in this, we can conduct the program one by one. Like MS-DOS (Microsoft Disk Operating System)
  • Multi-User Operating Software: This is an abundant operating system, in which we can manage more than one plant simultaneously. Under this, we can do multiple fabric inclination work on windows, Internet, playing media, etc. Like Windows, Linux, etc.

Application Software

Software that is used to business in a particular region called Application Software Like, MS office, Adobe Photoshop, etc.

Programming Software

These are the software’s that are necessary to renew scheme. with the befriend of this, we can erect a special plant to do a specific work. Like JAVA, HTML, FOXPRO, Visual Basic, etc.


There are principally Four main symbols of Devices in Computer

  1. Input Device: This opinion provides instruction to the computer. And inputs are made in changeable example of data computers, Like Keyboard, Mouse, Camera, Mice, etc.
  2. Output Device: This device shows us results that are being prevailed. That scheme is appeals to product devices, Like Monitor, Speaker, Printer, etc.
  3. Processing Device: The instructions given by the input device are narrative through this device, Like CPU (Central Processing Unit)
  4. Storage Device: The devices that stored the given data by the user, Like, Hard Disc, Floppy Disc, CD, Pen drive, etc.
  • CPU: CPU is a processing device on a computer. It is called the leading floor of the computer. This device works to operate the computer by combining all our inputs and production. This opinion comprises of two buttons and two LEDs.
