Introduction to Computer

A computer is a programmable machine designed to perform arithmetic and logical operations or work with Information automatically and sequentially on the input given by the user and gives the desired output after processing. Computer components are divided into two major categories namely computer hardware and computer software. Hardware is the machine itself or physical part of machine and its connected devices such as monitor, keyboard, mouse, cpu etc. Software are the set of programs that make use of hardware for performing various functions which we can't touch.

Computer is an advanced electronic device that takes raw data as an input from the user and processes it under the control of a set of instructions (called program), produces a result (output), and may saves it for future use. This tutorial explains the foundational concepts of computer hardware, software, operating systems, peripherals, networking, DOS commands etc. along with how to get the most value and impact from computer technology.


This tutorial has been prepared for students, beginners as well as advanced learners who want to deal with computers or study in a school, collages, university or attended a computer classess. The tutorial is also very useful for undergraduate students of computer science, engineering, business administration, management, science, commerce and arts, where an introductory course on computers is a part of curriculum.
After completing this tutorial, you will find yourself at a moderate level of expertise in the knowledge of computer basics from where you can take yourself to the next level.


Knowledge of computers is not a prerequisite to follow the contents of this tutorial. This tutorial assumes no background in Computers or Computer programming.
