What is Computer?

A computer is an electronic device which accepts data in the form of input and after processing it gives us information in the form of output with the help of output devices.

A computer is an electronic device designed to receive, process, store, and output data to perform various tasks efficiently and accurately. It consists of hardware and software components that work together to execute instructions and manipulate data.

Hardware Components: These physical parts comprise a computer and include:

1. Central Processing Unit (CPU): The brain of the computer responsible for executing instructions and performing calculations.
2. Memory (RAM): Temporary storage used by the CPU to process data and run programs.
3. Storage Devices: Such as hard disk drives (HDDs) or solid-state drives (SSDs) store data and programs even when the computer is powered off.
4. Input Devices: Keyboards, mice, touchscreens, and other peripherals used to input data into the computer.
5. Output Devices: Monitors, printers, speakers, and other peripherals used to display or produce processed information.
6. Hardware Circuit board connecting and facilitating communication among various /hardware components.

Software: Set of instructions that tell a computer what to do and how to do it.

Refers to the programs, applications, and operating systems that enable the computer to perform specific tasks. This includes:

1. Operating System (OS): Software that manages hardware resources, provides user interfaces, and facilitates interaction between users and the computer.
2. Applications: Software programs designed for specific purposes, such as word processors, web browsers, games, and design tools.

Functionality: Computers perform diverse functions, including:

1. Processing Data: Computers manipulate and process data through calculations, algorithms, and logical operations.
2. Storing Information: Data and programs are stored in several types of storage devices for future access and use.
3. Communicating: Computers enable communication via the internet, email, messaging, and networking technologies.
4. Executing Tasks: Performing a wide range of tasks, from simple calculations to complex operations, based on user instructions or programmed algorithms.
