Every company, irrespective of it's size, has to manage some kind of information. For example, companies need to store accounting entries, sales data, employee information, customers and suppliers contacts, etc. How do these companies manage information? Some manage it manually while others use digital means like computers. The technology which is used to manage any kind of information is called Information Technology.
The phrase 'Information Technology' does not refer to one kind of software or package. It is a generic term used for all kinds of software and hardware technologies used in managing information digitally.
The main objective of Information Technology is to provide the right information to the right person at the right time. It is rightly said,
'It is going to be a war of information rather than of weapons. One who manages information better will win.'
