Introduction

In today’s world, computer science and information technology are the major driving force of every industry. Computer science focuses on the application of computational theory to invent new ways to manipulate and transfer information. It is a branch of computer technology that is generally concerned with software, operating systems and implementation. It gives students the knowledge and understanding of how and why computers work the way they do. Thus, it enables students to create programmes and operating systems that do what they want it to do, thereby, customizing programmes according to the needs of the intended user.
