Short Essay on Computer 250 Words
A computer's a programmable device that accepts raw data(input) and processes it as output with a group of instructions (a program) to supply the result. It renders output after performing mathematical and logical operations and can save the output for future use. The word "computer" derives from the word "computare" in Latin, which means calculating.
Types of Computer
Computers are of different types based on different criteria. Based on their size, computers are of five types:
Micro Computers-
It is a single-user computer that has less capacity for speed and storage than the other types. For a CPU, it uses a microprocessor. Laptops, desktop computers, personal digital assistants (PDAs), tablets, and smartphones are common examples of microcomputers. Microcomputers are generally designed and built for general use, such as browsing, information search, the internet, MS Office, social media, etc.
Mini Computers-
Minicomputers are also referred to as "Midrange Computers." They are multi-user computers designed to simultaneously support multiple users. Therefore, they are generally used by small companies and firms.
Mainframe Computers-
It is also a multi-user computer that large companies and government organizations use to run their business operations as large amounts of data can be stored and processed. Banks, universities, and insurance companies, for example, use mainframe computers to store data from their customers, students, and policyholders.
Super Computer-
Among all types of computers, supercomputers are the fastest and most costly computers. They have an enormous capacity for storage and computing speeds and can therefore perform millions of instructions per second.
Workstations-
It is a single-user computer with a comparatively more powerful microprocessor and a high-quality monitor compared to a mini-computer.
Benefits of Computers:
It increases productivity.
It helps in connecting to the internet.
It helps in organizing data and information.
It allows storing large amounts of data.
Fun Facts About Computers
The first electric computer that was invented weighed around 27 tons or even more than that and took up to 1800 square feet.
There are about 5000 new viruses that are released every month.
The original name of Windows was Interface Manager.
Computer Essay in 500 words
Computers are electronic devices that store, process, and retrieve information. They have become a vital part of our daily lives, helping us perform tasks such as typing documents, sending emails, playing games, browsing the internet, and creating presentations or videos. While today’s computers are highly advanced, their early designs were primarily created for calculations.
This essay delves into the history, components, and uses of computers to understand their significance in modern society.
A Brief History of Computers
The concept of computers dates back to ancient times when simple tools like the abacus were used for calculations. During the Industrial Revolution, mechanical devices were created to automate tasks, like guiding patterns in weaving machines.
In the early 20th century, electrical machines capable of performing specific analogue calculations were introduced. These machines gradually evolved into digital computers, which are now classified into five generations, each marking a significant advancement in technology
Common Components of Computers
Computers consist of two main parts: hardware and software.
1. Hardware: Hardware refers to the physical components of a computer. These include circuits, chips, keyboards, monitors, and more. The five main hardware components are:
Input Devices: Tools like keyboards, mice, scanners, and barcode readers that allow users to input data into the computer.
Output Devices: Devices such as monitors, printers, and speakers that display or produce results in a human-readable form.
Control Unit: This part manages the computer’s various components, decoding instructions and coordinating tasks.
Arithmetic Logic Unit (ALU): The ALU performs all arithmetic and logical operations, such as addition, subtraction, and comparisons.
Central Processing Unit (CPU): Known as the brain of the computer, the CPU processes instructions and coordinates all tasks.
2. Software: Software includes the programs, data, and protocols that enable the hardware to function. It provides instructions for the computer to execute tasks. Software can be categorised into system software, like operating systems, and application software, such as word processors and games.
Uses of Computers
Computers have transformed nearly every field by enhancing efficiency and accuracy. Here are some areas where they play a vital role:
1. Science: Computers assist in collecting, analysing, and storing data. They help scientists collaborate worldwide and conduct complex simulations.
2. Government: In the government sector, computers are used to maintain citizen records, process data, and promote paperless systems. They also play a critical role in national defence.
3. Health and Medicine: Computers store patient information, monitor health metrics and aid in advanced medical equipment like X-rays and heart rate monitors. They also facilitate data exchange among doctors.
4. Education: In education, computers provide access to e-books, videos, and online classes. They help track student performance and organise online exams and projects.
5. Banking:Online banking systems allow customers to check balances, transfer funds, and pay bills. Banks also use computers to store transaction records and customer data securely.
Conclusion
It is surely known that the life of humans would not have been so easy if computers were not a part of human life. This is also supported by a lot of pieces of evidence where we can even see in daily life how the computer is not just present in an organization but is also available right in the pockets of everyone. Thus, the computer has surely made it easy while also spoiling a lot of people's lives.

2. What is the process of working on a computer?
A computer is an electronic machine and it needs information to be added in as raw data to function well. It has a flow that determines the accessing of data. The following steps take place before the results are obtained:
Information is taken in by the computer in the form of raw data. This process is also called the input.
Then the information that is not needed will be stored while the information that is needed is passed onto the next step. The storing of data is called memory.
Then the information that is required is crushed or it is split and this process is called processing.
The last step is where the results are obtained. This process is called getting the output.
