An internetwork is the connection of multiple different types of computer networks to form a single computer network using higher-layer network protocols and connecting them together using routers. The Internet is the largest example of internetwork. It is a global system of interconnected governmental, academic, corporate, public, and private ...
Clouds are used to represent networks external to the one pictured for the purposes of depicting connections between internal and external devices, without indicating the specifics of the outside network. For example, in the hypothetical local area network pictured to the right, three personal computers and a server are connected to a switch ...
The services and protocols specified in IEEE 802 map to the lower two layers (data link and physical) of the seven-layer Open Systems Interconnection (OSI) networking reference model. IEEE 802 divides the OSI data link layer into two sub-layers: logical link control (LLC) and medium access control (MAC), as follows:
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.
CYCLADES – a French research network created in the early 1970s that pioneered the concept of internetworking by making the hosts responsible for the reliable delivery of data on a packet-switched network, rather than this being a service of the network itself. Computer Science Network (CSNET) – a computer network created in the United ...
Example of a basic network diagram. Network documentation is a form of technical documentation, the goal of which is to maintain computer networks. [1] It contains information about how the network is built, how it should perform, and where to troubleshoot problems.
Also shown in this example (shaded in yellow) is the network's connection to the Internet via fixed-line means. A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, campus, or building, [1] [2] [3] and has its network equipment and interconnects locally managed. LANs facilitate ...
Network media refers to the communication channels used to interconnect nodes on a computer network. Typical examples of network media include copper coaxial cable , copper twisted pair cables and fiber-optic cables used in wired networks, and radio waves used in wireless data communications networks.
