A computer is an electronic device that processes data and provides information. It consists of both hardware and software. Hardware refers to the physical parts of a computer, such as the CPU, keyboard, mouse, and monitor. Software includes programs and the operating system that instruct the computer on what to do.
So, what exactly is a computer? It is a device that has become very important in our lives today. Computers make our difficult tasks easier because thinking is the computer’s job. We just give instructions to the computer through the keyboard and mouse
A computer consists of a CPU, monitor, keyboard, and mouse. The CPU does all the processing, and whatever we do is displayed on the monitor. We can do many things using a computer, like online shopping, ticket booking, playing games, and much more. Therefore, without a computer, our life remains incomplete. Nowadays, a computer is essential in every household. Let’s learn about what a computer is in Hindi.
What is the basic understanding of computer?
A computer is an electronic device that is very useful in our daily life. It is a machine that can store, process, and retrieve information. You can think of it like your brain, but it is much faster and more accurate. The computer makes our work easier and saves time.
A computer has many parts. It has a monitor that looks like a TV screen. We control the computer with the keyboard and mouse. The CPU is the brain of the computer. It does all the calculations. The hard drive is where we store our files and data. All these parts together make the computer powerful.
Role of Computers Today
Today, computers are everywhere—in schools, offices, hospitals, and homes. We can use them to surf the internet, play games, create documents, edit pictures, and much more. Computers have made our lives much easier. They keep us connected to the world and help us learn new things.
How Does a Computer Work?
A computer is like a magical machine that works very quickly. It is made up of four main parts: input devices, processor, memory, and output devices.
How a Computer Works:
- Input Devices:
Input devices are used to give information to the computer. The keyboard and mouse are the most common input devices. You tell the computer what to do with these. - Processor:
The processor is the brain of the computer. It understands and works on all the information. The processor works at a very fast speed and can do millions of calculations in one second. - Memory:
Memory is the computer’s memory. It is of two types – RAM and ROM. RAM is temporary memory that gets erased when the computer shuts down. ROM is permanent memory that stays even when the computer is off. - Output Devices:
Output devices are those that display the result of the computer’s work. The monitor and printer are the most common output devices. They show you the result of the computer’s work.
A computer works by combining all these parts. When you give a command, the input device sends it to the processor. The processor works on it with the help of memory. Then the result is displayed on the output device. All of this happens so quickly that it seems like the computer is responding instantly.
What is the Full Form of Computer?
Technically, a computer doesn’t have a full form. The full form of the word “computer” is simply “computer,” but there is an imaginary full form:
C – Commonly
O – Operated
M – Machine
P – Particularly
U – Used for
T – Technical and
E – Educational
R – Research
Features of a Computer:
The following are the features of a computer:
- Speed:
A computer is faster than humans at processing large amounts of data because it can perform many calculations quickly. - Accuracy:
Scientists and data analysts use computers for tasks that require precise results, such as scientific research and data analysis, because computers can calculate with high accuracy. - Reliability:

Computers are extremely versatile and can be used for a wide range of purposes, allowing them to be applied in fields such as science, engineering, business, entertainment, and many more.
How to Operate a Computer
For some people, it may be difficult to understand how to operate a computer. This section will help you understand how to use your computer easily.
You might be wondering how you can use the keyboard and mouse at the same time? Well, it’s not that complicated! Here are some instructions on how to do it:
- Move the mouse pointer to the icon or letter you want to click.
- Hold down the left mouse button.
- Drag the pointer to the location you want to click.
- Release the left mouse button when you reach the desired location.
History of Computers
The journey of computers started with calculating devices like the abacus, which was used for simple arithmetic calculations. Then, in the 17th and 18th centuries, more advanced mechanical machines like Pascal’s calculator and the Jacquard loom came into existence.
However, the real development of modern computers began in the 20th century. The Electronic Numerical Integrator and Computer (ENIAC), introduced in 1946, is considered the father of modern computers. Since then, computers have evolved rapidly, from large mainframe machines to personal computers in the 1970s and the powerful machines we have today.
Who Invented the Computer?
Father of Computer: Charles Babbage
While many people have contributed to the field of computing, Charles Babbage’s contribution is the most significant. He designed the Analytical Engine in 1837, which is considered the foundation for modern computers.
His engine included concepts like ALU (Arithmetic Logic Unit), basic flow control, and integrated memory. The modern computer design is based on this model. Therefore, he is known as the father of the computer.
Definition of Computer:
A computer is an electronic mechanical device designed to process input data, convert it into computational form, and display the results as output. Its name comes from the English word “compute,” which means “to calculate.”
A computer consists of various components, such as the CPU (Central Processing Unit), RAM (Random Access Memory), and storage devices (Hard Disk, SSD). Input and output devices like the keyboard, mouse, monitor, and printer are also important components.
The computer’s task is to transfer, process data, and display the final results. This is done through various software that consists of instructions that the computer follows.
Thus, the definition of a computer is a mechanical device designed to perform tasks automatically, process data, and provide accurate results.
Main Functions of a Computer:
Now, let’s look at the main functions of a computer:
- Input (Data):
Input is the step where raw information is entered into the computer using input devices. This could be a letter, picture, or video. - Process:
During the process stage, the input data is processed according to the instructions. This is an entirely internal process. - Output:
Output is when the processed data is displayed as the result. We can also save this result in memory for future use.
How Many Parts Does a Computer Have?
If you’ve ever looked inside a computer case, you must have noticed many small components. They may look very complicated, but they are not as complicated as they seem. Here’s some information about these components:
Computer Components in Hindi
- Motherboard:
The main circuit board of any computer is called the motherboard. It looks like a thin plate, but it holds many components, such as the CPU, memory, connectors for the hard drive, and optical drive, expansion cards for controlling video and audio, and ports for connections. The motherboard connects all the parts directly or indirectly. - CPU/Processor:
The CPU, also known as the central processing unit, is found on the motherboard inside the computer case. It is the brain of the computer, monitoring all activities inside the computer. The higher the speed of the processor, the faster it can process. - RAM:
RAM, or Random Access Memory, is the computer’s short-term memory. When the computer performs calculations, it temporarily stores the results in RAM. If the computer shuts down, this data is lost. That’s why you should save your work regularly to prevent data loss. - Hard Drive:
The hard drive is where software, documents, and other files are stored. The data remains stored for a long time. - Power Supply Unit:
The power supply unit takes power from the main power supply and distributes it to other components as required. - Expansion Card:
Every computer has expansion slots for adding expansion cards in the future. These are known as PCI (Peripheral Component Interconnect) cards. Many motherboards today already come with built-in slots.
Computer Hardware and Software:
Computer hardware refers to physical devices used in the computer, while computer software refers to the collection of codes installed in the machine’s hard drive to run hardware.
For example, the computer monitor we use for viewing is hardware, and the internet browser used to visit websites, as well as the operating system in which it runs, are considered software.
Types of Computers:
Computers come in two types: Analog and Digital. Analog computers require less power but take more time to process data, whereas digital computers require more power but process data much faster.
Desktop
Many people use desktop computers at home, schools, and for personal work. They are designed to be placed on a desk and have many parts, such as the monitor, keyboard, mouse, and computer case.
