Network service. In computer networking, 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 protocols.

Application-oriented networking (AON) involves network devices designed to aid in computer-to-computer application integration. Application-oriented networks are sometimes called "intelligent networks" or "content-based routing networks" and they are generally network technology that can use the content of a network packet or message to take some sort of action.
Application layer. An application layer is an abstraction layer that specifies the shared communication protocols and interface methods used by hosts in a communications network. [ 1] An application layer abstraction is specified in both the Internet Protocol Suite (TCP/IP) and the OSI model. [ 2] Although both models use the same term for ...
History. Computer networking may be considered a branch of computer science, computer engineering, and telecommunications, since it relies on the theoretical and practical application of the related disciplines. Computer networking was influenced by a wide array of technological developments and historical milestones.
The client–server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients. [ 1] Often clients and servers communicate over a computer network on separate hardware, but both client and server may reside in the same system.
An application delivery network ( ADN) is a suite of technologies that, when deployed together, provide availability, security, visibility, and acceleration for Internet applications such as websites. ADN components provide supporting functionality that enables website content to be delivered to visitors and other users of that website, in a ...
Systems Network Architecture[ 1] ( SNA) is IBM 's proprietary networking architecture, created in 1974. [ 2] It is a complete protocol stack for interconnecting computers and their resources. SNA describes formats and protocols but, in itself, is not a piece of software. The implementation of SNA takes the form of various communications ...
A network operating system (NOS) is a specialized operating system for a network device such as a router, switch or firewall.. Historically operating systems with networking capabilities were described as network operating systems, because they allowed personal computers (PCs) to participate in computer networks and shared file and printer access within a local area network (LAN).
