A ResNet (also Resnet or ResNET), which stands for residential network (or a variation of this phrase), is a local area network (LAN) or a metropolitan area network (MAN) provided by a university that serves the personal computers of students in their residence halls or dormitory buildings. ResNet may also refer to the department that administers such a network or the services provided via the network. A ResNet usually allows students to connect to a university's intranet with (possibly limited) access to the public Internet. ResNet is essentially the ISP for students residing in campus-managed housing.
The department, organization, or group responsible for maintenance of and support for the residential computer network is often also known as ResNet. This group may be an independent department in the central Information Technology division, the Housing department, or some other division or department. ResNet responsibilities may also lie not with a group dedicated to ResNet but may be one of many responsibilities such as those commonly held by help desks.
The functions of such a department vary greatly between campuses. Most, at least, provide assistance in connecting to the school's network. Other services may include the removal of viruses, adware, spyware, greyware, and malware, as well as services ranging from operating system or software and hardware advice to data recovery.
ResNet is slowly evolving into a full-blown computer Help Desk on many campuses, and in some cases has merged into a single support group for staff, faculty, and students.
Some ResNet organizations have branched from computer only support to alternate devices such as smartphones, PDAs, and gaming devices.
