"Information Technology Majors in High Demand Overseas: How Computer Technology Have Changed Our Lives?"

1. INTRODUCTION

The 21st century is the age of computer technology and it has brought about a fundamental change in every facet of our life. It has largely influenced the way we communicate and the way information exchange is facilitated in today's world. An emergent phenomenon that is a byproduct of advances in computer networking technology is the Internet. It has truly transformed the world into a global village, with every part of the world linked to its vast network. This happened out of the evolution of the field of information technology (IT), which harnesses the power provided by computer technology so, why is it Information Technology is in demand not only in our country and how does it affects our lives?

1.1. Background of Information Technology:

In the era of 1960s and 1970s, information technology was limited to people working in the banking sector, mathematical engineers and computer scientists. In 1980s, the arrival of personal computers made it possible to be used in many more sectors and gave rise to a surge in the field of information technology. Previously, for the purpose of business, storage tapes were created by a single network administrator to interconnect employee workstations. The information stored in this workstation was placed in a server farm, located far off from the industry. However, now people have started communicating, using e-mails instead of snail-mails. It is an industry which deals with the usage of computer hardware and software and networking. Information technology has accomplished a lot in the 21st century. IT is a combination of computer and communication technology and a transfer of information from one peer to another.

The backstory of information technology precedes the invention of the computer. The abacus, used by Asians, Egyptians, Romans, and the Greek can be termed a source of information technology. Calculators, the first mechanical one built by German polymath Wilhelm Schickard, or the slide rule, developed in 1622 by William Oughtred, also comes under the heading of information technology. Another example would be punch card machines, expanded upon by IBM in the early to mid 1900's, qualifies the term information technology.

As time progress along with the advances of inventions and applied knowledge, computing took shape and became useful in a variety of ways other than calculations. Computer science became an academic specialty, creating computer science departments and classes. As these classes took shape, separate branches of computer science became distinct areas of study. Today, Information Technology departments use computers, data centers, servers, database management system, specialized software applications and more, managed by system and database administrators, an Information Technology Manager and other department heads, including a Chief Information Officer (CIO). Even though information technology has a long reach into history, only recently has it been associated with the use of computers.

1.2. Definition of Information Technology:

When the terminology 'information technology' is used, mistakenly it describes the entire industry. Information technology basically refers to the employment of computer hardware and software applications to manage data. The term 'information technology' evolved in the 1970s and if we consider a medium or large company providing goods or services, its information technology department will be responsible for storing, protecting, processing, retrieving and transmitting the information (Information Technology Association of America or ITAA). Information, meaning processed form of raw data, is something to be valued with your life in today's world. A person possessing right kind of information and using it at the right time, can surely work wonders. From the credit card numbers which we use for...
