IT Department Overview

The information technology department in an organization is responsible for handling all the technological issues that arise and enables the company’s employees to communicate, collaborate and perform their role duties. The IT department is responsible not only for technical support an employee may be having, but is also responsible for programming, website updates, hardware, software and networking. Some companies may have a single IT employee while other larger organizations may hire a team of people within the company’s IT sector or IT infrastructure that work together to keep the network and company up and running.
