A computer is an electronic device that is used to accomplish many complex tasks, such as managing big data, performing complex calculations, printing, controlling heavy machinery and complex security systems and more. They are used in almost every field due to their high efficiency, almost an error and zero ease of functional ease and excellence.
(1) 250 Words – Essay on Computer Uses in English for Kids & Students in Very Easy Words
A computer is a device that is used for many purposes such as storing records and data, printing and performing other complex tasks. Their high level of utility has made use of computers in almost every office, schools and homes today.
Here are some areas where computers are used:
Hospital
Hospitals will have to keep many records. They have to keep records of their patients, their medical history, last visit dates, addresses, diagnoses etc. They also have to keep stock of medicines available and update it regularly. It would be an impossible task to maintain such a large amount of data related to different topics if it had to be done manually. Computers make this huge-looking job much easier by storing gigabytes of information in their memory and revealing the information at the simple push of a button.
School and office
Computers in schools are primarily used for education purposes and to maintain relevant data of students and staff, as well as in offices for a wide range of purposes. Computers in schools have all the academic and personal records of students. This includes everything from the grade to the person’s contact number in case of an emergency.
Railway station
Computers are also widely used in railway stations. They are used in the operation of locomotives, signs and systems, as well as for the very basic yet important work of booking and printing passenger tickets.
The conclusion
Computers are widely used in almost every business location for their efficiency and ease of adaptability. Today any business will be stable without computers.

400 Words – Essay on Computer Components in English for Kids & Students in Very Easy Words
A computer is a machine that can perform complex tasks according to the instructions provided by humans. His high efficiency and ability to perform any task has brought him widespread use.
Computer components
Any computer has mainly three main components – the input (I / p) device, the central processing unit (CPU) and the output (O / p) device.
- The input device is used to feed instructions to the computer. Keyboard, joystick, touch pen are some examples of input devices.
- The central processing unit is the brain of a computer. It consists of arithmetic and logic units (ALU) and memory units. The ALU performs all complex tasks while the memory unit stores data and information.
- The output device is used by the user to display the desired output. Some of the most common output devices are monitors and printers etc.
Type of computer
Based on their architecture, size and performance, computers can be classified into different types listed below-
- Supercomputer
A supercomputer is a high-performance computer that performs much better than a general-purpose computer. Supercomputers require large spaces, often a large room or hall and an effective cooling mechanism to operate.
- Mainframe computer
Mainframe computers are used by large organizations for bulk data processing, enterprise resource planning (ERP), census etc. They are larger than personal computers and also have higher processing power and speed.
- Personal computer
A personal computer is a computer that is used for personal use. Its unique size, capacity and value make it suitable for use as a personal computer. Mainframes and supercomputers, by contrast, are not shared personal computers and are operated by only one owner.
- The laptop
A laptop is also a type of personal computer, but unlike traditional personal computers, desktops, it is easy, portable and lightweight. The laptop is easy to carry and is so light that it can be comfortably placed on your lap.
- Smartphone
Today, widely used smartphones are also a type of mobile computing device. They operate on their own operating systems; They provide them with a wide range of features such as software optimization and internet, web browsing, camera and more.
The conclusion
Modern day computers are used in almost every industry depending on the needs and requirements. Every device, from supercomputers to laptops, is uniquely useful in its own way and varies widely in price and specification.

600 Words – Essay on Computer History in English for Kids & Students in Very Easy Words
A computer is an electronic device that is used to perform complex arithmetic and analytical tasks far beyond the human’s natural ability. Computers are highly efficient devices and perform really fast and accurately. The output generated by the computer is accurate and there is no possibility of error other than human error.
History of computer
The computer has a long history and has many stages of development. Some believe that an early calculation tool called ‘Abacus’ carried forward the invention of calculators and computers. However, the abacus was only a mechanical device consisting of tools made of wooden beads that could run on thin rods or wires. Even to this day ac abacus’ has retained its original form and has no electronic or electrical parts.
Difference Engine
The first mechanical computer was developed by Charles Babbage, not before 1822. This machine was called the ‘differential engine’. Charles Babbage is often called the ‘father of computers’; His invention was completely different from modern day computers.
Analytical Engine
This machine was a proposal made in 1837 by Charles Babbage. This included ALU (arithmetic and logic unit), flow control, punch cards and integrated memory. It was the first concept to build a general-purpose computer. But unfortunately, due to financial problems, this concept of Babbage never materialized during his lifetime. However, his son Henry Babbage was able to develop a part of the machine as conceptualized by Charles Babbage sooner than 1910.
Z1 – First Ever Programmable Computer
This computer was developed by a German inventor named Konrad Zeus. He developed it in the living room of his parents during 1936–1938, while he was around 26 years of age. The ‘Z1’ was the first binary programmable computer and the real predecessor of modern-day computers.
Turing machine
This machine was proposed in 1936 by Alan Turing. Turing was a mathematician and computer scientist based in the United Kingdom. The Turing machine was capable of emulating and printing symbols and algorithms on a paper tape.
The colossus
The Colossus was a group of machines developed by the British during World War II. These were developed by British code breakers, during 1943–1945 to read high-level messages from the German Army during World War II.
First digital computer
The first digital computers used plus 300 vacuum tubes and could perform mathematical calculations and Boolean logic. It was also called Atanasoff-Berry Computer (ABC Computer), after its two inventors, John Vincent Attanasoff and Cliff Berry. He developed it from 1937–1942 at Iowa State College, now Iowa State University.
First Electronic Computer (ENIAC)
ENIAC is an abbreviation for electronic numeric integrator and calculator, developed in 1943 by J. Presper Eckert and John Mauchly at the University of Pennsylvania. It was huge, heavy and 1800 square feet. It also used 18,000 vacuum tubes and weighs about 50 tons. It was the first fully functional digital computer.
First computer company
The first computer company was founded in 1949 and was named the Electronics Control Company. It was founded by two individuals who helped form ENIAC – J. Presper Eckert and John Mauchly.
The conclusion
Modern computers have evolved over hundreds of years to reach efficiency and size that we see today. But, evolutionism is not over yet and will continue for centuries to bring new technological progress to help humans.
