The most basic information technology definition is that it's the application of technology to solve business or organizational problems on a broad scale. No matter the role, a member of an IT department works with others to solve technology problems, both big and small.
There are three primary pillars of responsibility for an IT department:
- IT governance: This refers to the combination of policies and processes that ensure IT systems are effectively run and in alignment with the organization’s needs.
- IT operations: This is a catchall category for the daily work of an IT department. This includes providing tech support, network maintenance, security testing and device management duties.
- Hardware and infrastructure: This focus area refers to all the physical components of IT infrastructure. This pillar of IT includes the setup and maintenance of equipment like routers, servers, phone systems and individual devices like laptops.
