NIOS Class 12 Computer Science — Chapter Summary

A computer is an electronic machine that accepts input, processes it, and produces desired output. It is a combination of hardware (physical components like CPU, monitor, keyboard) and software (programs and operating systems). Understanding computer fundamentals is essential as computers have becom

Binary Logic is the fundamental foundation of all digital computing systems. It works exclusively with two states represented by 0 (false) and 1 (true), which align perfectly with how electronic circuits operate using ON/OFF states. This chapter explores how computers represent and process all types

Computer software is the set of instructions and programs that tell a computer's hardware what to do. Without software, a computer is just an inert machine. Software acts as the bridge between the user and the physical components of the computer, enabling it to perform calculations, store data, and
