Brief Definition Of Computer

BRIEF DEFINITION OF COMPUTER

Introduction

In today's modern world, computers are everywhere and everywhere. In supermarkets it is used to manage what is sold. Banks use it to keep track of account balances, and televisions have built-in computers that help you switch channels. Computers are now also used in schools for teaching, grading, and processing results. As you've read, computers are tools that allow anyone to do certain tasks faster and easier.

You don't have to be an engineer to drive a car, so you don't have to be an electronics engineer or a math genius to use a computer. They are machines that help us in our daily lives, made by people, for people. There are no magic machines, nothing mysterious.

What is a computer?

A computer is a specialized multi-purpose electronic device capable of receiving, storing and processing instructions (data) and delivering desired results as incredibly fast and accurate outputs. (mechanical).A computer as a system is a set of interconnections/components intended to achieve the same goal. Computer as a system consists of
Software Hardware

Hardware

Hardware refers to the physical units or components that make up a computer configuration. Computer hardware has her three main components: processors, peripherals and auxiliary hardware.

THE SOFTWARE

Software refers to programs processed by hardware. A program is a set of instructions executed by hardware to solve a specific problem or program a specific task.
Computers can't do anything unless you tell them to. Computer software contains a set of instructions that enable computer hardware to perform specific tasks.

Features of Computers 

All computers, regardless of type or size, have some common features.

Arithmetic: Can perform complex activities and arithmetic operations.

Programmable: Can be programmed to complete complex, tedious and monotonous tasks.

Power: Computers are very powerful.
Your computing power is measured in word length.

Digital computers work with binary numbers (0's and 1's). The language that computers understand is in the form of 0's and 1's.
binary numbers are called bits.

A collection of 8 bits is called a byte. Word length is the number of bits a computer can process in parallel at one time.

Commonly used word lengths are 8, 16, 32, or 64. The larger the word length, the more powerful the computer.

A 64-bit computer has a 64-bit word length, which is more powerful than a 32-bit computer.
Speed: The computer computes very fast and correctly
As your computer's performance improves, so does its speed. H. Supercomputers are more powerful and faster than microcomputers.
Information Storage and Retrieval: Computers can store large amounts of data. There are main memory and auxiliary memory. With more secondary storage devices capable of storing large amounts of data, computer storage capacity becomes almost unlimited. What makes this even more amazing and unique is the speed with which you can get the information you need in seconds.

To check your memorization of a word in your dictionary, it takes minutes to turn pages, but the computer returns it in seconds. Therefore, the

computer can store and retrieve large amounts of data quickly and efficiently.
Accuracy: Computers have a very high degree of accuracy. Error detection and correction techniques prevent erroneous results in the event of hardware errors. However, human error often leads to inaccurate results. If the data entry operator enters wrong data, the computer accepts and processes it.

The result is also wrong. This is called Garbage In Garbage Out (GIGO).
Versatility: Computers are very versatile
Almost any task can be accomplished if it can be reduced to a logical set of steps. You can do calculations, create complex computer-aided design (CAD), model and simulate, pilot rockets and satellites, and more.

Computers can communicate with each other. You can also send and receive data in various formats such as graphics, sound, video and of course text. This ability gave birth to the computer network that is the heart of the Internet and the World Wide Web (WWW). It is thanks to the performance of the personal computer that the reply comes back immediately after sending the e-mail.
Automata: When properly programmed, computers can achieve incredible levels of automation. Once a task has started, the computer can automatically continue until it completes without error. It also has internal capabilities to monitor operational parameters.
Diligence: Computers process information with honesty, fidelity, and obedience. They are immune to human weaknesses such as boredom. Fatigue, Exhaustion, Depression, Poor Concentration. The same operation can be performed repeatedly with the same precision and speed.
Networkability: Allows you to connect computers to form a network. Networks can connect to other networks. Networks Extend Computer Capabilities
Information Technology

Almost every area of ​​human thought and behavior requires information
Information is needed to plan and purchase meals, but organizations need information to make decisions.

Dates are raw facts, events, or activities that have no meaning. Data can be facts about people, places, things, and their activities.

Data is said to be "processed" when it undergoes some manipulation or activity in order to organize it in a meaningful way or to achieve a desired result. Information is the result of processed data.

Information is the result obtained from the processed data. It is meaningful and can be communicated to all users in the form of news and knowledge. Information consists of data, images, text, documents and language. These are often intertwined, but always wisely organized.

Information technology is the use of computers and telecommunications equipment for automated information processing.

"Information". The dissemination of information was by "town criers," even in the setting of the It is recorded that it was a communication
With industrialization came various information transmission technologies, or what we call communication technologies.

The Media of Electronics
The dissemination of information through the invention of electronics was a welcome development as it outperformed printed materials such as radio, television, telex, telephone, facsimile and video conferencing. These media have the direct advantage of disseminating information quickly and to a wider audience. Computers are at the heart of it, playing an increasingly important role in many forms of communication automation.

The rapid pace of computerization and technological innovation has brought about what has been called the microelectronics revolution. Computers connected to modems exchange messages (voice, data, and graphics) via satellites around the world.

Information Communication Technology A general term for technologies that support communication via computers. This means Internet or local area network, e-mail, and World Wide Web technologies.

A computer network is a connection of computer systems. Computer networks have the ability to grow and change their nature. Computers are networked to share resources. Common resources are information, computer systems (software and hardware), and people.

Certainly. Note that messages can be sent within the same building. This is called an intranet. This may or may not require a phone code. A message sent between two buildings. Connections using computers are called local area networks (LANs), and messages sent and received between cities are called wide area networks.
