Information Technology – A Complete Guide

This guide has been created to help readers form a basic knowledge of Information Technology (IT). When considering computer and processing technologies, it is possible to distinguish IT into four distinct developmental stages – pre-mechanical (3000 BC – 1450 AD), mechanical (1450 – 1840), electromechanical (1840 – 1940), and electronic (1940 – present). This guide will primarily focus on the most recent period, electronic, beginning with a brief history of IT and how computers were perceived. This guide will then consider the impact of the internet, with a look at the most predominant companies dealing in the IT industry, and ending by exploring the modern implications and future of IT.
