Information Technology, or IT, also cited as Information Service (IS) or Management Information Service (MIS), can be defined as the development, design, study, implementation and management of computer related information. It can also be defined as the use of computer - hardware and software - to manage information.

The Evolutionary IT Sector

In the era of 1960s and 70s, information technology was limited to the workforce at the banking sector, mathematical engineers, and computer scientists. In the 1980s, the arrival of personal computers made it possible for IT to be used in varied sectors, where this field witnessed its premiere upsurge. Formerly, for business purposes, 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, people have now started communicating using emails 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. It is the transfer of information from one peer to another.

Importance of Information Technology

Information technology is used for storing, protecting, processing, securing, transmitting, receiving, and retrieving information. In business establishments, it is used predominantly to solve mathematical and logical problems. Information technology helps in project management systems as well. Firstly, planning is done, then the data is collected, sorted and processed, and finally, results are generated. It helps managers, and workers to inquire about a particular problem, conceive its complexity, and generate new products and services; thereby, improving their productivity and output. The primary importance of information technology with regards to education is that various learning resources can be accessed instantly by students as well as teachers, with paramount importance laid on the convenience factor. Learners can also adapt to the multimedia approach, coupled with collaborative learning. The information is authentic with the updated information being widespread in terms of availability. Multiple communication approaches, like, chats, forums, emails, etc., can be adopted by them. Students may access the online libraries, in turn having distance learning programs perform a successful feat. In addition, IT has proved to be a significant employer. Many people with knowledge of computers have got jobs in this field, and have successfully made a career out of it. It has helped one find cures for several diseases; thereby, serving mankind in plentiful ways. Different kinds of software are provided for individuals with visual, or hearing impairment; thereby, aiding them in their passion to learn new concepts, and gather information parallel to their subject of interest. Information technology, as aforementioned, functions in the background; nevertheless, it is also the backbone of the organization. If the IT system falls short of resources in order to make ends meet, the organization's efficacy is hampered. The IT workforce has become such an indispensable section of the organization that we expect it to function with absolute lucidity and alacrity; however, when this scenario ceases to exist - even if it is for a brief period - the infrastructural base of communication endures a beating. The IT profession has opened doors to communication which is constructively channelized, being debarred from display of opacity of any form. In addition, the IT sector has been coveted the apotheosis of flexibility. Be it an employee, or an entrepreneur, any given location could be his virtual work-station. You may conduct your office work even when you are not in your designated seat. Working from home is a steeplechase concept, gracefully adapted by organizations aplenty, with flexibility being its unique selling proposition. In this manner, your organization remains endowed with its necessary functioning - a behooving quality for any and every business enterprise to thrive. Communication is made easy with the overt influx of technology. Right from its inception, technology has never remained indolent; on the contrary, it has striven to prove its renewed potency with each passing day. I trust this article has given you an idea about why information technology is important in this day and age, also enlisting its advantages. The IT sector has developed tremendously and will continue doing so in/for the future. With the current scenario, it is, indeed safe to say that IT is the new 'It' sector. Ergo, when an enterprise is sealed with IT professionals that exhibit an undying, and relentless restlessness to achieve operational excellence, business just doesn't survive . . . it thrives! . . .
