What is Information Technology IT Definition

The Information Technology (IT) department manages the technology and computer infrastructure that drives an organization's business systems. The IT department is also known as Management Information Systems (MIS or IS) department.

The IT department is staffed with technically competent professionals that support the organization in these critical areas:

		Much of an organization’s computer processing is performed by end-users using their desktop PC. When these end-users incur a computer problem (unable to logon, printer does not work, etc.), they call the IT department for technical support. Depending on the nature of the problem, the IT department may assist the user over the phone or send a technician to their location.
		Managing individual desktop computers, laptops and peripherals is a cornerstone of the IT department tasks. Desktop management of individual computers includes: installation of new hardware components or software, software license administration, equipment repair and maintenance.
		Making sure that the computer network is always available with safe and secure data is the most important task for the IT department. Not only does this involve the physical installation of cabling throughout the facility, but also the installation and monitoring of the firewall, servers and other equipment to keep the network running at peak efficiency.
		The IT department maintains the telephone and computer systems that allow employees to connect with other employees, customers and suppliers through the use of voice mail, email, faxes, message boards, Internet and intranet web sites. This includes coordinating new requirements with third-party service providers.
		Developing and maintaining the business systems that operate the organization are essential tasks of the IT department. This includes software for financial, manufacturing, sales and distribution systems, as well as general office administration, such as word processing and spreadsheet applications.
		The IT department is responsible for creating and executing a strategic technology plan that keeps the organization up-to-date with technology advances and ensures that equipment and software do not become obsolete. The technology plan also focuses on the requirements needed to support new business growth.
