Dear Learners, here we are providing you the link for the Computer Fundamentals PDF which will give you the basic knowledge of the computer system and its mechanism. As we all know that technology has become the integral part of our lives. We use technology for most of the work at personal and professional level. So it becomes important to get familiar with the Computer Fundamentals. Actually, Computer is an electronic device that takes raw data as input from the user and processes it and produces a result (output) to user.
The term computer is derived from the word “computare”.The word is derived from a “Latin” word which means to calculate.Therefore computer refers to a programmable machine that is used for some numerical calculations.
