The word Information technology is often associated with the computer generation, it is as old as the word itself. In this article, the term “information technology” means the modern science of digital information and its various properties such as recording, use, and transmission through computers.
The First Computers!
The first Computers were integrated circuits on a single chip. Around the year 1980, the first computers were available which were priced suitably. In 1977, the first computer by Apple, Apple II was launched and soon after IBM came out with their PC in 1981. in the late 80’s the revolutionary Graphical User Interfaces (GUIs) came into the scene. This program allowed the users to look at their screens with windows; also the clickable commands and color appeared. In 1983 Windows was introduced in the market and simultaneously the first Apple Macintosh was launched in 1984.
With the rapid development of computers, in 1965, Gordon Moore gave a law. He predicted that the number of transistors on a computer chip would double every 18 months. Gordan Moore is the co-founder of the world’s leading computer chip manufacturer, Intel. His rule was true for chips for about thirty years. In the current scenario, the speed of the chips has declined to some extent but the density of data involved in computer functions has followed Moore’s law.
Software Programs that take a lot of Computer Memory are introduced
To keep up with this exploding industry, there was a simultaneous introduction of chips that were faster and could handle software programs using a lot of memory and hard drives that were constantly upgrading its capacity. About a decade and half ago, computers with 24 MB of RAM was adequate for general use. Today, the most common users need computers with more than a gigabyte – a forty-fold increase! Similar trends have been visible in standard computer data-memory capacity.
From stand alones to Networks
The world of IT on the same time has moved from working on stand-alone computers to networks of computers. Transfer of information and data has contributed immensely to the world of business. Networking has helped in providing access to common databases, resulting in the database becoming the main source of business records for a number of organizations. Software utilizing these databases has become a highly profitable industry. Customer Relationship Management (CRM) software drives business activities for many big organizations which are occupied in product sales across the global markets
Information Technology Introduces Us to a Friend We’ll Never Forget
Information technology has also brought us the Internet. The web has become a primary communications device via email. It has become a full color, multimedia advertising platform for millions of small businesses. It has become a sales tool for increasing numbers of retailers, large and small. This, in turn, has led to an IT industry with software that handles online transactions, tracks shipping, and distributes orders within the business itself. Information technology has made it possible to make purchases online, and online sales have risen billions of dollars each year over the last five years – doubling in some of those years.
In a related field, information technology has made it possible to pay our bills and do our banking online. The Internet is on its way to replacing Main Street as the primary commercial avenue in this country. It’s an industry that will continue to grow larger and add access into new areas of our society for some time to come.
