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.

In order to perform these functions, 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).

Information Technology – Trends

Going forward, the Information Technology Department 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. The job outlook for those within the Information Technology organization is extremely strong, with data security and server gurus amongst the highest paid techies.
