Unit 3: Information Technology

In this unit, we will learn more about the Information Technology side of MCO.

Information Technology can be defined as the use of technology to manage and process information. This can be a broad label. At times, the term is used instead of saying computer or computer network.

Careers in IT often fall into the storage, transmission, manipulation, retrieval, or protection of data but can also deal exclusively with hardware. IT professionals can be help desk technicians, Chief Information Officers, networking administrators, cybersecurity specialists, and much more. Job responsibilities can include support, management, administration, and security (including ethical or white hat hacking).
