Introduction of Computer – Are you a student, and you also like to keep a lot of knowledge of computers or do you also want to learn how to run the computer from basic to advanced, then you have come to the right place?
In this blog post, you will be told completely basic about the Definition of a Computer, what is a computer, when a computer is made, who built it, parts of it, everything is made.
Trust me, after this article, you will understand very well What is a Computer, and why the computer is so important in our life.
So let’s get started !!
Definition of Computer | Introduction of Computer
A Computer is an electronic machine that was made to do calculations, this machine saves the command given by a user and then processes that save command and gives a result to the user which is called output.
“User gives input, Computer saves input
and processes that input, Then gives the output to the user “
The word computer is derived from the word “compute” in English which means “to calculate”. So it is clear that the computer is directly related to the calculating machine.
At present, its area has become very large, not limited to just counting. The computer is becoming important in every area of our life due to its high storage capacity, speed, automation, efficiency, accuracy, universality, power of remembering.
Calculations can be done by the computer at a much faster pace over time. The results given by the computer are more accurate.
Nowadays computer is used everywhere like a computer, school, college, airplane, bank, and hotels, etc. are used everywhere. All the work is happening more rapidly due to computers.
Hardware and Software
Before we talk about different types of computers, we know about 2 things which are normal in all computers: Hardware and Software.
Hardware is any part of your computer that includes physical communication, such as a keyboard or mouse. It also includes all the internal parts of the computer.
In simple language, all the parts of the computer that we can touch and see with our hands are called all the hardware, we can open our computer and touch all its parts, that is, every part inside the computer We will also call it hardware.
Software is any set of instructions that tells the hardware what to do and how to do it. Examples of software include web browsers, games, and word processors, etc.
In simple language, just like you run apps on your Android mobile phone, there are also apps in the computer which we call “computer software” or just “software”. Therefore, all the parts of the computer that we cannot touch with our hands and can only see them being accessed are called software.
Different types of Computer
When most people hear the word computer, they think of computers like desktops or laptops. However, computers come in many sizes, and they are used for a variety of tasks.
The work of a people is done by keeping the computer in only one place, such as in labs in schools, in hospitals, in homes, etc. These computers are designed to work in one place, which we call “desktop computers”.
A laptop computer is usually called a laptop. You can use a laptop computer anywhere, so business people use it more so that they can use it anywhere and anytime.
A tablet is a computer that is more portable than a laptop. Instead of a K-board and mouse, tablets use a touch-sensitive screen for typing and navigation.
A server is a computer that can pass information over the network to other computers. You can keep your data online in these servers as well as display that data on the Internet.
A person does a lot of work in his life but only remembers the important works, but the computer stores the data of all those who do the work so that it can be seen anytime when needed.
What is Input and Output Devices
The hardware parts of the computer are also divided into two parts, input devices, and output devices, Because of these devices, we are able to use a computer, so it is said that the computer gives output only after taking inputs.
These are those parts of the hardware from which the user gives the computer what the computer has to do, for example – the user types “A” on the keyboard or clicks on an application with the mouse. So the device from which the user gives input to the computer is called the Input Device.
These are those parts of the hardware from which gives to the user output of his given input, for example – the user types “A” on the keyboard and users get output on Monitor or A user clicks on an application with the mouse and users get output on Monitor. So the devices from which the user gets his output are called Output Devices.
