Information Technology - Definition and History

Information Technology – A Definition:

We use the term information technology or IT to refer to an entire industry. In actuality, information technology is the use of computers and software to manage information. In some companies, this is referred to as Management Information Services (or MIS) or simply as Information Services (or IS). The information technology department of a large company would be responsible for storing information, protecting information, processing the information, transmitting the information as necessary, and later retrieving information as necessary.

History of Information Technology:

In relative terms, it wasn't long ago that the Information Technology department might have consisted of a single Computer Operator, who might be storing data on magnetic tape, and then putting it in a box down in the basement somewhere. The history of information technology is fascinating! Check out these history of information technology resources for information on everything from the history of IT to electronics inventions and even the top 10 IT bugs.

Modern Information Technology Departments:

In order to perform the complex functions required of information technology departments today, the modern Information Technology Department would use computers, servers, database management systems, and cryptography. The department would be made up of several System Administrators, Database Administrators and at least one Information Technology Manager. The group usually reports to the Chief Information Officer (CIO).

Popular Information Technology Skills:

Some of the most popular information technology skills at the moment are:
For more information about technical skills that are popular in the job market, check out the IT Career Skills List..

Information Technology Certifications:

Having a solid education and specific specialty certifications is the best way to progress in an information technology career. Here are some of the more popular information technology certifications:

Jobs in IT:

There can be a lot of overlap between many of the job descriptions within information technology departments. In order to clarify the descriptions, skills and career paths of each, I have put together a Jobs in IT listing. The jobs in IT listing includes information on education and training required for each position. It also includes lists of companies that typically have IT jobs open, as well as links to IT-specific resumes, cover letters and IT interview questions.

Information Technology - Trends:

Information Technology Departments will be increasingly concerned with data storage and management, and will find that information security will continue to be at the top of the priority list. Cloud computing remains a growing area to watch. The job outlook for those within Information Technology is strong, with data security and server gurus amongst the highest paid techies. Check out the Information Security Certifications and Highest Paying Certifications for more information. In order to stay current in the Information Technology Industry, be sure you subscribe to top technology industry publications.




The word “ Computer” is derived from a Latin word “ Computare” which means “ to Calculate” More formally computer can be defined as: It is an electronic machine that receives input as data, process it into a meaning full from, and generates information as output.


It has always been a keen desire of human being to make his work easy to do. So, man was busy inventing different machines. In case of ease in Calculation the first attempt was made by Chinese.
v     Chinese developed the first computer of history (ABACUS),  3000 BC.
v     In 1617 John Napier made his first or first every mechanical Calculating device as Napier Bone.
v     Blaise Pascal, in 1642 made his mechanical Calculator which was smarter in operation then Napier Bones.
v     In 1801 Jacquard invented his machine, named Jacquard Loom. This machine was using punched card for creating pattern on a loom.
v     In 1803s Charles Babbage is conceived first programmable computer known as Analytical Engine. Analytical Engine could perform mathematical Calculations using punch card. Thus Charles Babbage is termed to as “ Father of Computer”.
v     Dr. Herman Hollerith developed first electro-mechanical punched card Tabulator in 1890.
v     The first Analog Computer was invented by Dr.Bush in 1930.
v     In 1942-44 H.Aiken at Harward University mode the first electro-mechanical Computer in assistance of IBM company.
v     In 1948 Transister was invented, which reduced the size and cost of Computer to an extant.
v     In 1970s large Scale integrated developed, using this technology, further microprocessor was made which shrunk the size of Computer and now Computer was available commercially.
Gradually, developments were made both in software’s and Hardware’s and today Computer is more general purpose to solve our every day problems.
