Computer
A computer is an electronic device that processes, stores, and retrieves data. It can perform complex calculations, manipulate data, and execute instructions based on programmed software. Computers consist of hardware components such as a central processing unit (CPU), memory (RAM), storage devices, input/output (I/O) devices, and a power supply. Software programs or operating systems are installed on computers to provide users with the ability to interact with the computer and perform tasks such as word processing, browsing the internet, or playing games. Modern computers can be desktops, laptops, tablets, or mobile phones, and they are used in a wide range of applications, from personal use to scientific research and industrial automation.

Why is it known as data processor ?
A computer is known as a data processor because it processes or manipulates data in various ways. Data processing is the collection and manipulation of data to produce useful information. This involves several steps such as inputting data, sorting, classifying, calculating, summarizing, and presenting the results.
When you input data into a computer, it is stored in its memory. The CPU then performs calculations and manipulations on the data based on the instructions provided by software programs. This processing may include data transformation, analysis, or computation, depending on the specific task being performed.
The output generated by the computer can take many forms, such as reports, graphs, or other visualizations that help users understand the data. Thus, a computer is known as a data processor because it takes in raw data, processes it according to predefined rules, and outputs useful information that can be used for decision-making and other purposes.
