The Information Department, usually called IT Department, Computer Department and Information Department, is in charge of enterprise computer, network maintenance, enterprise management software maintenance and research and development.
Usually, small and medium-sized enterprises have only one or two IT personnel, who are mainly responsible for network management and computer maintenance. Usually called network management, it is often not an independent department, but exists as a sub-department or post of personnel department, administrative department or financial department. For medium and large enterprises, there are often nearly ten people or even more, mainly because the company's computer peripheral products need more manpower, and there are often internal software research and development, and most of them are independent into a first-level department, parallel to the finance department, human resources department and engineering department.
So the important thing is not to belong to which department, but to find out the job responsibilities of the information department.
