Core network components interconnect other network components. Gateway: an interface providing a compatibility between networks by converting transmission speeds, protocols, codes, or security measures. [2] Router: a networking device that forwards data packets between computer networks.
Network architecture is the design of a computer network.It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used.
Networking hardware typically refers to equipment facilitating the use of a computer network. Typically, this includes routers, switches, access points, network interface cards and other related hardware. This is a list of notable vendors who produce network hardware.
Wi-Fi provides wireless access to the Internet via local computer networks. Hotspots providing such access include Wi-Fi cafés, where users need to bring their own wireless devices, such as a laptop or PDA. These services may be free to all, free to customers only, or fee-based. Grassroots efforts have led to wireless community networks.
The collection of addresses in the network is called the address space of the network. Examples of telecommunications networks include computer networks, the Internet, the public switched telephone network (PSTN), the global Telex network, the aeronautical ACARS network, [1] and the wireless radio networks of cell phone telecommunication providers.
OSI had two major components: an abstract model of networking, called the Basic Reference Model or seven-layer model, and a set of specific protocols. The OSI reference model was a major advance in the standardisation of network concepts.
Computer network engineering is a technology discipline within engineering that deals with the design, implementation, and management of computer networks. These systems contain both physical components, such as routers , switches, cables, and some logical elements, such as protocols and network services .
