INTRODUCTION TO COMPUTER AND ITS BASIC KNOWLEDGE (GK PART 16)

Introduction to computer and its components

Hello students/everyone , Almost every exam contains one general awareness/general knowledge section. Maximum students are afraid of this section. General knowledge/general awareness has no end, but to improve it we have to start it from a scratch. I have written some points on ” INTRODUCTION TO COMPUTER AND ITS BASIC KNOWLEDGE” “Introduction to computer and its components” which will help you a lot in remembering basic points which easily slips ones mind duriing exams. These introduction to computer and its basic knowledge/Introduction to computer and its components points are very important as per exam point of view. For any special request feel free to contact us.

It will take maximum 10 minutes to have a look on it (INTRODUCTION TO COMPUTER AND ITS BASIC KNOWLEDGE)(Introduction to computer and its components). For Any questions and inquiries related computers feel free to contact us.
