What is a computer, in simple language, it is a machine that can process data and do calculations. The Term “Computer” refers to the hardware, software and firmware used to process data. Computers have been in use since the early 20th century, but they became widespread in the 1980s with the advent of the personal computer.
So we can call a computer such an advance electronic device that takes raw data from the user as input. Then processes that data through a program (set of instruction) and publishes the final result as output. It processes both numerical and non-numerical (arithmetic and logical) calculations. What is a computer and know a little from bed.
What is Computer?
A computer is an electronic device that can be programmed to automatically perform a set of arithmetic or logical operations. This is the easiest answer to what a computer.
A computer has three main components: input, processing and output. Input is usually a keyboard and mouse. The processing component is usually in the form of a microprocessor or central processing unit (CPU). Output is usually on a display screen, such as a monitor or television.

How does Computer work?
A computer is a device that is used to store, process and transmit data. They are used for anything from storing files and documents to sending emails.
Computer are electronic devices that can store and process data through the use of microchips. The first computer was invented in the 1940s by a team of scientists led by British mathematician Alan Turing. The computer was designed to calculated artillery tables for the British Army.
The word “Computer” is derived from the word “Compute”, Which means “to figure out”. Computers have been around since 1938 when they were invented by British mathematician Alan Turing.

2. Press and hold the left mouse button.
3. Drag the pointer to the spot you want to click.
4. Release the left mouse button when you reach the desired destination.
Who invented computer?
Contributed in this computing filed. But out of all these the
contribution of Charles Babbage is more. because it Was he who first
came out with the Analytical Engine in the year 1837.
The concept of ALU, Basic Flow Control and Integrated Memory was
Implemented in his engine. today's computer Were designed on the basis of this model only. today's Why his contribution is maximum. That`s why he is also known as the father of computer.
Definition of Computer
A computer is an electronic device that manipulates data according to a list of instructions called a program.
The term computer has been in use since the early 17th century, when it refers to a person who calculating machine. The term continued to refer to these workers through the 19th century and into the 20th century and into the 20th century until it was later applied to “a machine that automatically calculates”.

Computer Work
Input (Data): Input is the step in which raw information is entered into the computer using input device. It can be a letter, picture or even a video.
Process: The data input during the process is processed according to the instruction. This is completely internal process.
Output: The data that has already been processed during the output is shown in the form of the result. And if we want, we can save this result and keep it in memory for future use.
Main parts of computer
If you have ever seen inside a computer case, then you must have found that there are many small components inside, they look very complicated in reality. Now I will give you some information about these components.
Motherboard
The main circuit board of any computer is called Motherboard. It looks like a thin plate but it is holding many things. Such as CPU, Memory, Connectors for hard drive and Optical Drive, expansion card to control video and audio, as well as connection to all ports of the computer. If seen, the motherboard is directly or indirectly connected with all the parts of the computer.
CPU/Processor
Do you known what is Central Processing Unit i.e. CPU? This is also called it is found in the motherboard inside the computer case. It is also called the brain of the computer. It keeps an eye on all the activities inside a computer. The higher the speed of a processor, the faster it will be able to do processing.
RAM
We also know RAM by the name of Random Access Memory. This is the short-term memory of the system. Whenever the computer does some calculation, it temporarily save that result in RAM. This data is also lost if the computer is turned off. If we are writing a document, we should save our data in between. By saving, if the data is saved in the Hard Drive, it can remain for a long time.
RAM is measured in megabytes (MB) or gigabytes (GB). The more RAM, the better it is for us.
Hard Drive
Hard Drive is the component where software, documents and other files are saved. In this, the data remain stored for a long time.
Power Supply Unit
The work of the power supply unit is to take power from the main power supply and supply it to other components as per the requirement.
Expansion Card
All computers have Expansion Slots so that we can add an Expansion Card in the future. These are also called PCI (Peripheral Components Interconnect) cards. But nowadays there are already many slots built-in in the motherboard. Names of some Expansion Card that we can use to update old computers.
✅ Video Card
✅ Sound Card
✅ Network Card
✅ Bluetooth Card (Adapter)
If you are ever opening the internal things of the computer, then you should first remove the plug from the main socket
Computer hardware and software
We can call computer hardware any physical device that we use in our computer, whereas computer software means a collection of codes that we install in the hard drive of our machine to run the hardware.
For example, the computer monitor that we use to read, the mouse that we use to navigate are all computer hardware. The same Internet Browser from which we visit the website, and the Operating System in which that Internet Browser runs. We call such things as software.
We can say that a computer is a combination of software and hardware, both have similar roles, both can work together.
Type of computer
A computer is a type of machine that people use to calculate information. Computers are often called the brain of the modern world because they are used in almost every industry and for many different purposes.
There are two types of computers, Analog and Digital. Analog computers require less power but require more time to process data, while digital computers require more power but require less time to process data.
Whenever we hear the use of the word computer, only the picture of personal computer comes in our mind. Let me tell you that there are many types of computers. Comes in various shapes and sizes. We use them according to need, such as ATM to withdraw money, scanner to scan a barcode, calculator to do any big calculation. These are all different types of computers.
1. Desktop
Many people use desktop computers for their homes, school and for their personal work. Their design is such that we can keep them on our desk. They have many parts like Monitor, Keyboard, Mouse, Computer Case.
2. Laptop
you must have known about Laptop which are Battery Powered, they are very portable so that they can be taken anywhere and anytime.
3. Tablet
Now let’s talk about Tablet which we also call Handheld Computer because it can be easily held in hands.
There is no keyboard and mouse in it, just a touch sensitive screen which is used for typing and navigation. Example – I-pad
4. Servers
A Servers is some type of computer that we use to exchange information. For example, whenever we search for something in the Internet, all those things are stored in the server only.
