A metropolitan area network (MAN) is a large computer network that interconnects users with computer resources in a geographic region of the size of a metropolitan area. Wide area network. A wide area network (WAN) is a computer network that covers a large geographic area such as a city, country, or spans even intercontinental distances. A WAN ...
Network architecture. 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. In telecommunication, the specification of a network ...
e. The Spanning Tree Protocol ( STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include backup links providing fault tolerance if an active link fails.
Routing is the process of selecting a path for traffic in a network or between or across multiple networks. Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet . In packet switching networks, routing is the ...
Computer network diagram. A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. Computer network diagrams form an important part of network documentation.
Software-defined networking. Software-defined networking ( SDN) is an approach to network management that enables dynamic and programmatically efficient network configuration to improve network performance and monitoring in a manner more akin to cloud computing than to traditional network management. [1] SDN is meant to improve the static ...
Router (computing) A router [a] is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet. [2] [3] [4] A router is connected to two or more data lines from different IP networks. When a data packet comes in on a line, the router reads the network address ...
Packet loss occurs when one or more packets of data travelling across a computer network fail to reach their destination. Packet loss is either caused by errors in data transmission, typically across wireless networks, [1] [2] or network congestion. [3] : 36 Packet loss is measured as a percentage of packets lost with respect to packets sent.
