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 shopping, to the confidential bank account details, everything is stored in the form of binary digits in computers. These details can be used or misused depending on what kind of people have authorized or unauthorized access to it. With the help of information technology and our increasing dependency on machines, our life has become far easier, but we are more vulnerable now than before.

Information Technology (IT) is a wide and varied sector, and is represented in some form in almost all the industries. It is a blend of computers and communication technology where IT professionals perform variety of duties, ranging from development and installation of applications to designing complex computer networks and databases. The information technology industry consists of computers, communication mediums, peripherals, electronics-related organizations, softwares and services.

Usage of information technology for the completion of tasks in any organization, speeds up the processing and information mobility, and also improves the reliability and integrity of information. Information technology, while stirring thoughts and visions of networks, the Internet, server rooms, racks of switches and routers, and advanced terms including VoIP, TCP/IP addressing, security and more, the ‘technology’ doesn’t necessarily refer only to computer related issues. Any medium or channel that stores and processes information enters the category of information technology.

The brain is an information processor, working to process and manage information that controls our every movement, body functions, and habits. Whichever procedure or attempt to communicate, store and manage information as well as utilize and administer the data will fall under the classification. 1. 3. Components of IT: * Computers: Computers are very important in order to store and process data. Depending on the size, cost and processing ability, computers are divided into four categories. They are mainframes, supercomputer, minicomputers and microcomputers (desktops or personal computers). Servers: A server is a combination of hardware and software, and is used to provide services to the client computers. These services generally include storage and retrieval of information. A standalone computer can also act as a server, provided it’s running on server operating system. * Database Management Systems (DBMS): Database Management System is basically a set of software programs which manages the storage and retrieval and organizes the information in a computer. This information is in the form of a database and is managed with the help of software.

The DBMS accepts requests from the application program and instructs the operating system to transfer the appropriate data. There are various departments to monitor the flow of information, which include System Administrators, IT Managers, Database Administrators and Chief Information Officers (CIOs). * Networking: A computer network is a collection of computers and peripherals connected to each other through different modes. These modes can be wired or wireless. The network allows computers to communicate with each other (share information and resources like printers, scanners, etc. ). Network Security and Cryptography: Network security is one of the most important aspects of information technology. It consists of all the provisions made in an underlying computer network, in order to prevent unauthorized usage of information. It also includes implementing the policies adopted by the government and the applicable cyber laws. It is also helpful in providing protection from computer hacking at the cyber boundaries of an organization. The cost of transmitting information has fallen dramatically, and according to a study, the cost of transfer of one trillion bits of information from

Boston to Los Angeles has come down from a whopping $150,000 in 1970 to merely 12 cents today. With the help of internet technology, emailing a document of 40 pages from Chile to Kenya costs less than 10 cents, which is nothing as compared to the faxing price of $10 or sending it by courier for $50. Hence, it can be clearly seen that there are many advantages of information technology and it has drastically decreased the cost of information transfer. It has also increased the efficiency of employees in all organizations, allowing them to focus on core competencies rather than the technological issues. 2. LITERATURE REVIEW

Using a computer to write about computers is like searching for ‘Google’ on Google! Computer technology is so much a part of our lives, that we cannot imagine a life without it. Computers serve as efficient data storage systems and excellent information processors. They can store, organize and manage huge amounts of data. Moreover, they operate on incomparable speeds, thus saving human time and effort to a large extent. True, they are an integral part of our lives. It is said that inventions change the way we live. Computer technology is a classic example of this adage. It has indeed changed our way of living. . 1 Made IT in demand abroad: Information Technology or IT departments for some of the largest corporations in the world, in an effort to keep up with increased demand for database administrators, computer support specialists, computer scientists, computer engineers and systems analysts, have recently started recruiting graduating IT degree students from top tier universities. The shift toward finding qualified personnel prior to graduation is a stark departure from years past when IT guru’s were competing for the few available positions that weren’t outsourced to overseas companies or individuals.

Outsourcing has again become a major concern for corporations, not because of increased profits or savings, but because of the lack of IT personnel available in the U. S. and in some countries. In fact, the U. S Bureau of Labor Statistics indicates that 8 of the 10 fastest growing occupations between now and 2010 will be computer related. This sudden shift in employment opportunities has led to high demand for IT degree program graduates especially abroad.

After a period in which IT was considered a poor career choice following the tech stock fallout of the mid to late nineties and massive job cuts for major IT employers, those graduates are now harder and harder to find. Many corporations have relegated customer support operations to overseas companies while returning their database administrators and network support specialist positions to the U. S and some foreign countries. As security concerns over data theft and system security has become more prominent as of late, many of these positions are returning to these shores as well.

The impact this is having on job availability for recent grads can only be described as positive. Enrollment numbers for IT degree programs are on the rise as well, which is a good sign that many are taking note of the current employment market for IT specialists. With the turnaround in IT employment coinciding with an increase in enrollment, many industry analysts are predicting that current shortages will be met over the next several years.
