What is Computer?
Computer is an electronic device that performs mathematical and non-mathematical operations. It takes data as input, processes it and provides meaningful results as output. We collect raw facts in the form of data and these data are entered into the computer. The computer processes these data and provides us information. Nowadays many tasks can be done through computers.
Hardware and Software: Hardware are the physical parts of a computer, such as CPU, monitor, keyboard, mouse, etc.
Software is a computer’s programs and operating system that help the hardware run.
Operating System: The operating system controls all the software and hardware of the computer. Examples: Windows, macOS, and Linux.
Word Processing: Word processing software is used to prepare documents and reports, such as Microsoft Word.
Spreadsheet: Spreadsheet software is used for data entry, calculations, and data visualization, such as Microsoft Excel.
Internet and Web Browsing: The Internet is a part of the computer network that allows you to search online, use email, social media, and other websites.
How many parts are there in a computer?
A computer has many parts that help it perform various tasks and functions. These are some of the main ones.
- A central processing unit (CPU)
- A graphics processing unit (GPU), also known as a video card.
- Random access memory (RAM), also known as volatile memory.
- Storage: Solid State Drive (SSD) or Hard Disk Drive (HDD)
How does a computer work?
The functioning of a computer system is based on the combined use of both input and output devices. Using Input Devices, we can instruct the computer to perform an action and through Output Devices we can achieve the final result. This is how a computer works through input and output devices.
What is input device?
A piece of equipment/hardware that helps us enter data into a computer is called an input device. For Example Keyboard, Mouse, Microphone, Scanner, light pen, Joystick, Barcode Reader etc.
What is Output Device?
A piece of equipment/hardware that gives the result of the entered input once it is processed, i.e. converts the data from machine language to human understandable language is called output device. For Example Monitor, Printer, Speaker, Projector, Headphone Etc.
History of Computer?
The first digital computer was named ENIAC. It was created during World War II (1943–1946) and was designed to help automate calculations being performed by human computers. By doing these calculations on a computer, they could get results much faster and with fewer errors.
Early computers like ENIAC used vacuum tubes and were very large. Were found only in businesses, universities or government institutions. Later, computers started using transistors and smaller and cheaper parts, so that even a common person could keep that computer in his home and use it easily.
