Information Technology does not mean computer literacy but how computers can be use for Information processing and problem solving tasks. Information Technology covers almost every aspect of our daily lives from business to leisure and even society.
Today PCs, cell phones, fax machines, pagers, email and internet have all not only become an integral part of our very culture but also play an essential role in our day to day activities.
It is mainly due to the IT industry that people from diverse cultures are able to personally communicate and exchange valuable ideas. Business can be able to operate 24 hours, even from remote locations.
The Information Technology (IT) refers to the creation, gathering, processing, storage, and delivery of information. Information technology can :
- Process raw data into useful information.
- Recycle process information and use it as data in another processing steps.
- Pack information in a new form so it is easier to understand, more attractive, or more useful.
In the broadest sense, information technology refers to both the hardware and software that are use to store, retrieve, and manipulate information.
In general System can be define as “A group of interdependent items that interact regularly to perform a task”. E.g: Gravitational system is a system as it is a group of interacting bodies under the influence of related forces.
A Computer System refers to the hardware and software components that run a computer or computers.
Information Systems :
An Information System can be view as a work system where all activities are devoted to different types of digital processing. Information Technology is somewhat different from Information System, as the later is generally seen as a component of the former one, i.e. communication technology.
Information System also helps to control and manage the activities and performance of a business process. Computers, stored facts, instructions and procedures are the main components of a typical information System.
The basis of an Information System is the sharing and processing of information and ideas. Computers and telecommunication technologies are now becomes an essential and very useful information system components.
Applications of Information Technology in everyday life :
(1) I.T in Business :
Transactions with suppliers, employees, or customers are involves in most of the business activities. These transactions are not possible without Information Processing Systems. IT has made it possible for business to be open 24×7 over all the globe. This means that a business can be open anytime anywhere.
(2) I.T in Industry :
Information technology has major impact in industries where products are design and manufacture. Computer Aided Design (CAD) is use to design the products and computer aided manufacturing is use to produce them.
(3) I.T in Product Manufacturing :
Computer Aided Manufacturing (CAM) is the use of computer software to control machine tools and related machinery in the manufacturing. CAM may also refer to the use of a computer to assist in all operations of a manufacturing plants.
(4) I.T at Home and Play :
From the comfort of your home you can research school or work assignments, exchange e-mail, download files, play games or make railway reservations. From any computer with an internet connection, you can read the newspaper, shop online, or read reviews of the movies. Home shopping and Banking are now becomes very fast growing areas of computing.

Students find it easier to refer to the internet than searching for information in books. The process of learning has gone beyond learning because of Information Technology. Online education has revolutionizes the education industry.
(6) I.T in Science and Engineering :
Information Technology play a major role today in every field of scientific research from genetic engineering to astrophysics research. One of the prime uses of Information technology in pure science and engineering projects is the running of simulations. To understand the human body and to diagnose disorders in human body, Physicians uses Information Technology.
