Network Support System

A network support focuses on the maintenance of an existing corporate network, either as part of the organization’s internal IT support team or as technical support staff of a third-party network technology provider. Network support may extend from testing and troubleshooting problems to regular maintenance. Support engineers contribute high-level support such as strategic planning of network upgrades and high-level network performance analyses.

A network service is an application running at the network application layer and above, that provides data storage, manipulation, presentation, communication or other capability which is often implemented using a client-server or peer-to-peer architecture based on application layer network protocol.Each service is usually provided by a server component running on one or more computers (often a dedicated server computer offering multiple services) and accessed via a network by client components running on other devices. However, the client and server components can both be run on the same machine.
