What is Computer Definition

What is Computer Definition: Do you know what is computer definition? A computer is a programmable machine. This means it can execute a programmed list of instructions and it responds to the new instruction given.

Currently, this term is most commonly used for desktop and laptop computers that most people use. When referring to a desktop model, the term computer simply refers to a computer – not monitors, keyboards, and mice (mouse). Nevertheless, it is acceptable to mention all things together as a computer. If you want to be really technical, the box that the computer holds is called the “System Unit”.

It has three main functions. The first is to take the data we also call the input, the second is to process that data and another task is to show the processed data, also called output.

There are many components to any modern digital computer, but some of them are very important such as input device, output device, CPU (central processing unit), month storage device and memory.

Who invented the computer first? (Information About the Computer)

The father of modern computers is Charles Babbage. He designed the first technological computer (analysis engine). In this, the data was washed using a punch card.

So you can call computer an advanced electronic device that takes raw data from the user in the form of input, then processes that data through a program and finally releases the result, making it both numerical and non-numeric (mathematical and Logical) processes calculations.

The concept of ALU, Basic Flow Control and Integrated Memory was implemented on this engine. Today’s computer was based on this model. That is why his contribution is the highest. Everyone called him father of computers.

What is Computer Full Form?

Technically there is no complete computer full form. Yet the computer has an imaginary full form.

In the case of computer generation, this means the generation of computers as computers grow, they are divided into different generations to make them easier to understand.

First Generation of Computer – 1940-1956 (Vacuum Tubes)

In these generation computers used vacuum tubes and magnetic drums in memory. They used to be very big. A lot of energy was used to run these.

Being very large, it also had a lot of heat problems which caused it to be faulty at times.

Second Generation of Computers – 1956-1963 (Transistors)

In second-generation computers, transistors replace vacuum tubes. The transistors took up very little space, were smaller, were faster, were cheaper, and were more efficient. They used to generate less heat than the first generation computers but still had heating problems.

They used high-level programming languages such as Cobol and Fortran.

Third Generation of Computers – 1964-1971 (Integrated Circuits)

Integrated circuits were first used on third-generation computers. In which the transistors were cut into little silicon chips that are called semiconductors. Because of this, the capacity of computer processing has increased greatly.

For the first time, monitors, keyboards, and operating systems were used to make this generation of computers more user-friendly. It was first introduced to the market.

Fourth Generation of Computers – 1971-1985 (Microprocessors)

This is the fourth generation specialty in which the microprocessor was used. Through which thousands of integrated circuits were embedded in a single silicon chip. This makes it very easy to reduce the size of the machine.

The use of microprocessors has increased the efficiency of the computer. This very work was able to count a lot.

Fifth Generation of Computers – 1985 to Present (Intelligence Artificial)

The fifth generation of today’s doorstep, where artificial intelligence has established its dominance, has now begun to use many new technologies such as speech recognition, parallel processing, quantum computation.

This is a generation in which the ability to make decisions on their own has gone away due to artificial intelligence. Its works will be automated.

How does Computer Works? (Information about the computer)

Input (data): Input is the step by which raw data is entered into a computer using an input device. It could be a letter, a picture, or a video.

Process: During the process, the information is processed according to the input instructions. It is a completely internal process.

Output: The result that has already been processed during the output is displayed. And if we want, we can preserve this result and keep it in memory for future use.

If you’ve ever looked at a computer, but certainly found that there are many small elements inside, they look very complicated, but they aren’t that complicated. Now, I will give you some information about these elements.


The motherboard is called the main circuit board of any computer. It looks like a thin plate, but it has a lot of things like CPU, memory, hard drive and optical drive connectors to control computer ports as well as extension card video and audio. If seen, the motherboard is connected directly or indirectly to all parts of the computer. What Is A Motherboard?

CPU / processor

Do you know what a central processing unit is? It is also called. In the case of computers, it is available on the motherboard. You can tell it is the head of a computer. It monitors all the activities of a computer. The higher the processor speed, the faster it will be able to process. What is A Processor in Computer & How it Works?


We know RAM as a random access memory. It is a short-term memory of the system. Whenever the computer does something, it temporarily saves the RAM result. If the computer closes, this data may also be lost. If we are writing a document, we should preserve our data in order to prevent it from spoiling. If stored, the data is stored on the hard drive, it may remain for a long time. What is RAM & How It Works?

RAM is measured by megabytes (MB) or gigabytes (GB). 

Hard drive

Hard drives are components that store software, documents, and other files. In it, data is stored for a long time. Difference Between SSD and HDD

Power supply unit

The power supply unit of the work is the power supply unit from the supply to the other components as per its demand.

Expansion card

All computers have extension slots so we can add an extension card in the future. But nowadays there are already a lot of slots built into the motherboard. Here are some expansion card names we can use to update old computers.

  • Video Card
  • Sound card
  • Network Card
  • Bluetooth Card (Adapter)

Computer hardware and software

Computer hardware that we use on any physical device on our computer, which means that we collect the codes installed on our machine’s hard drive to operate the hardware.

For example, the computer monitor we use to navigate, the mouse we use to navigate is all computer hardware. At the same time, the internet browser we visit the website with and the operating system where that Internet browser operates. We call this thing as software.

We can say that the combination of computer software and hardware, both have the same role, both can work together.

Types of Computer (Information about the Computer)

The image of the personal computer only comes to mind when we hear the use of computer words. Let me tell you that there are many types of computers here. They come in different shapes and sizes. We use them as needed, such as ATMs to withdraw money, scanners to scan barcodes and calculators as a computer.

1. Desktop

Many people use desktop computers for their home, school, and personal work. They are designed so that we can keep them at our desk. They have many parts such as to monitor, keyboard, mouse, computer case.

2. Laptop

You must know about battery-powered laptops, they are very portable so they can be taken anywhere and anytime.

3. Tablet

Now let’s talk about the tablet which we also call a handheld computer because it can easily be caught in handguns.

It doesn’t have a keyboard and mouse, just a touch-sensitive screen that is used for typing and navigation. Examples- iPad.

4. Servers

A server is any type of computer that we use to exchange information. For example, all these things are stored on the server whenever we search for something on the Internet.

Other types of Computers

Let’s now know what our other types of computers are.

Smartphone: When the Internet is capable of a normal cell phone, there is a lot we can do using it, then this national cell phone is called a smartphone.

Wearable: A generic term for a pair of wearable tech devices, including fitness trackers and smartwatches – these were designed to be worn all day long. These devices are often called wearables.

Game Console: This game console is a special type of computer used to play video games on your TV.

TV: TV is also a type of computer that now incorporates many applications or applications to convert it to smart TV. We can see all the videos from the Internet to our TV.

Some Uses of Computer

Where is the computer used? If seen, we are using a computer anywhere in our life and will continue to do so. It has become a part of us. I’ve written a few uses for your information below.

Use of computers in education: They have the biggest hand in teaching if a student needs any information about a subject, then with the help of this information it becomes available within minutes. Research has shown that the performance of any student with the help of the computer has increased significantly. Nowadays classes can be taught at home with the help of classes.

Entertainment and Recreation: This has become a new hangout for talking about entertainment, new movies, sports, or restaurants wherever they are used.

Government: Nowadays the government is paying more attention to their use. If we talk about traffic, tourism, information, and broadcasting, education, aviation, our work in all these places have become very easy.

Defense: Their use in the military’s power has increased greatly. With which our army has now become more powerful. Because nowadays everything is controlled with the help of computers.

There are many places where we use it to suit our needs.

Benefits of Computer

However, it would not be wrong to say that the computer has made our lives very comfortable with our incredible speed, accuracy, and storage.

With it, people can save anything and easily find it whenever they want. We can say that the computer is a very versatile machine because it is very flexible in its functions.

Nevertheless, we can also say that a computer is a versatile machine because it is extremely flexible in the way it works, while these machines also have some important advantages and disadvantages.


It is the biggest advantage of the computer. It allows us to easily calculate huge tasks, many operations, numerical problems in seconds.

Computers can easily count in trillions of instructions per second.


Now, this is not just a counting device. Now it has become an important part of our lives.

The great advantage of this is its high speed, which helps it finish a task in a very short time.

In it, all operations can be done immediately, otherwise, it will take too long to do so.

Prices/stores make a lot of data

It’s a low-cost solution. Because it allows a person to store a lot of data at a low budget. Using a centralized database can save huge amounts of data so that the cost can be maximized.


These computers are very accurate about their calculations, the chances of them being wrong are minimal.

Information Security

Protecting digital data is called data protection. Computers protect us from unauthorized users such as digital data cyberattacks or access attacks.

Some Disadvantages of Computer

Attack viruses and hacking

The virus is a destructive program and hacking is called unauthorized access so the owner doesn’t know about you. How Antivirus Works?

These viruses can be easily spread through email attachments, sometimes via USB, or accessed from your infected websites by your computer.

At the same time, once it reaches your computer, then it destroys your computer.

Cybercrime online

Computers and networks are used to online cybercrime. At the same time, cyberstalking and identity theft are also covered by this online cyber-crime.

Reduce employment opportunities

Since computers are capable of performing many tasks at once, there is a huge loss of employment.

So, from the banking sector to any public sector, you can see that all computers are given more importance in the public place. So, unemployment is only increasing.

Speaking of other disadvantages, it has no IQ, it is entirely up to the user, it has no feelings, it can not make any decision on its own.

The Future of Computers

However, there are a lot of technological changes coming to the computer day by day. Every day, it is becoming more affordable and more efficient and more efficient As the needs of the people increase, so will the change. Earlier it was the size of a house, now it is in our hands.

Now scientists are doing more research on optical computers, DNA computers, neural computers, and quantum computers. In addition to this, a lot of attention is being paid to artificial intelligence so that it can do its job well.
