Access networkAn access network is a section of telecommunications or internet network which connects users or devices to their immediate service provider. When referring specifically to Internet Service Provider (ISP) or other service provider infrastructure, they are commonly referred to as "last mile" networks that connect ISP distribution infrastructure to end users, such as a consumer, business, or organization.

Internet backboneThe Internet backbone is the principal data routes between large, strategically interconnected computer networks and core routers of the Internet. These data routes are hosted by commercial, government, academic and other high-capacity network centers as well as the Internet exchange points and network access points, which exchange Internet traffic internationally.Routing in the PSTNRouting in the PSTN is the process of forwarding telephone calls between the constituent telephone networks that comprise the public switched telephone network (PSTN). Telephone calls are routed across a network of potentially many switching systems, often owned by different telephone carriers. Switching systems are connected with trunks. Each switch may have many neighbors. Neighboring switches owned by different operators are connected at interconnect points.Computer networkNetwork that allows computers to share resources and communicate with each otherMetricsAlgorithmsCentralityGroup centralityDegreeMotifClusteringDegree distributionAssortativityDistanceModularityEfficiency ModelsListsCategoriesTopicsSoftwareNetwork scientistsIn computer science, computer engineering, and telecommunications, a network is a group of communicating computers and peripherals known as hosts, which communicate data to other hosts via communication protocols, as facilitated by networking hardware.
Router (computing)A router is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet. Routers perform the traffic directing functions on the Internet. A router is connected to two or more data lines from different IP networks. When a data packet arrives on a line, the router reads the network address in the packet header to determine the next path towards the destination.Network congestionNetwork congestion in computer networking and queueing theory is the reduced quality of service that occurs when a network node or link is carrying or processing more load than its capacity. Typical effects include queueing delay, packet loss or the blocking of new connections. A consequence of congestion is that an incremental increase in offered load leads either only to a small increase or even a decrease in network throughput.Gateway (telecommunications)A gateway is a piece of networking hardware or software used in telecommunications networks that allows data to flow from one discrete network to another. Gateways are distinct from routers or switches in that they communicate using more than one protocol to connect multiple networks and can operate at any of the seven layers of the OSI model.
Public switched telephone networkThe public switched telephone network (PSTN) is the aggregate of the world's telephone networks that are operated by national, regional, or local telephony operators. It provides infrastructure and services for public telephony.
Local area networkA local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, campus, or building, and has its network equipment and interconnects locally managed. LANs facilitate the distribution of data and the sharing of network devices, such as printers.
SubnetA subnet, or subnetwork, is a logical subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting. Computers that belong to the same subnet are addressed with an identical group of most-significant bits of their IP addresses. This results in the logical division of an IP address into two fields: the network number or routing prefix, and the rest field or host identifier.*As an Amazon Associate I earn from qualifying purchases.
