The document provides an overview of computers including: 1. Computers accept input, process data, store data, and produce output. They are electronic devices that can perform calculations quickly and accurately. 2. Computers have large memory, can be programmed for different tasks, and never get confused or tired like humans. 3. There are two main types of computers - analog and digital. Digital computers are now more common and represent data using binary numbers.

2. How Computer Works

3. Definition: Computer Computer can be defined as “An electronic and electromechanical device capable of receiving data, processing the data inputted, and generating the output in the form of information”. In the definition, we come across some terminologies such as electronic, electromechanical device etc. An electric device is that device which runs by electricity. An electromechanical device is one which performs mechanical movements upon receiving the electricity. Whatever we are inputting into the computer will be treated as Data and whatever has been generated by computer will be treated as Information.
