It gives more effective and speedy solutions to real life problems. People lead complex lifestyles that need most suitable solutions within shortest time. ICT satisfies these requirements in a comprehensive manner. Hence today has become the IT or ICT age. Few instances where IT or ICT is heavily used * Home: Hobbies, Entertainment, Household bills amp; accounts etc. * Everyday Life: Supermarkets, Banks, Hospitals, Security amp; Defense etc. * Education: Libraries, Simulation of laboratory experiments on computers, Computer Aided Learning- CAL etc. Engineering: Chemical plants, Oil refineries, Manufacturing of cars etc. * Commercial/ Industrial: Air amp; road traffic controls, Travel amp; transportation etc. Elaboration of above topics is mentioned below : Application| Usage | Home| Most of the time computers at home are usedFor writing letters, sending and receiving e-mail, Playing games, browsing the internet to gather information, for shopping, to watch movies and just about anything| Supermarkets| The computer has a record for each item with information such as the item number, name, description, price, quantity in the stock etc. The central computer is able to identify the item number by using the bar code reader. Once identified, the number is sent to the central computer, which in turn sends the information that corresponds to the item to POS terminal to be printed. The computer also does the necessary stock adjustments by subtracting the quantity sold of the particular item. IT is used to automate manual accounting systems such as ledger, sales and purchases, stock control. | Banks (ATM, Transactions, Tele banking, Credit card payments)| All transactions are entered then and there by the teller so that work doesn’t get accumulated. Each transaction as it is entered is updated in the master file at the central computer. The teller just types in the account number and he is given instant access. | Educational Administration| IT is used to automate school administration activities such as keeping records of students, examination results, normal office work and communication with other schools via e-mail etc. | Education (Computer Assisted School Administration)| In subjects such as biology, chemistry, physics laboratory experiments can be simulated on the computer. The computer can be used to explain vast concepts more vividly by using its ‘graphics’ capability to display pictures, diagrams and even videos. Some experiments can be done virtually. Video conferencing. For distant learning, Use of World Wide Web in finding information. CAL (Computer Assisted Learning) the computer presents material, asks questions based on the students performance, determines whether to present new material or review topics already covered. | Library| A library contains thousands of books, magazines, and other items which a borrower may wish to borrow. Maintaining records of books and borrowers can be a complicated and tedious job but may well suit a computer system.

It is used in all fields of air traffic. Every aircraft has a small computer fitted to help pilots in various ways. | Medicine (Chemical Analysis, CT, MRI, US Scanning, ECG, EEG, Surgery)| In hospitals special computers are built inside different equipment. Ex: CAT scanners (Computer Axial Tomography). Further maintenance of patients’ records in electronic databases enhances services provided. | Defense amp; Security (Signal operations, Missile guidance amp; Nuclear plant operations)| IT is very useful in tracking down criminals through the maintenance of their databases. In warfare computers are used to guide missiles. | Engineering| Engineers use IT to prepare drawings of machines, tools, bridges, buildings etc. (CAD-Computer Aided Designing). Also computers are used to control manufacture of items. (CAM-Computer Assisted Manufacture). The use of Robots in industries is another example| Entertainment| This basically covers video games, music and movies played back by computers with multimedia facilities. | Conclusion Through all these information it is clearly identified the importance IT to modern world: that IT is an integral part of modern life.
