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.
Networking hardware, also known as network equipment or computer networking devices, are electronic devices that are required for communication and interaction between devices on a computer network. Specifically, they mediate data transmission in a computer network. [ 1] Units which are the last receiver or generate data are called hosts, end ...
A network interface controller ( NIC, also known as a network interface card, [ 3] network adapter, LAN adapter and physical network interface[ 4]) is a computer hardware component that connects a computer to a computer network. [ 5] Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus.
Network topology is the topological [ 4] structure of a network and may be depicted physically or logically. It is an application of graph theory [ 3] wherein communicating devices are modeled as nodes and the connections between the devices are modeled as links or lines between the nodes. Physical topology is the placement of the various ...
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.
Wide area network. A wide area network ( WAN) is a telecommunications network that extends over a large geographic area. Wide area networks are often established with leased telecommunication circuits. [ 1] Businesses, as well as schools and government entities, use wide area networks to relay data to staff, students, clients, buyers and ...
Networking cable is a piece of networking hardware used to connect one network device to other network devices or to connect two or more computers to share devices such as printers or scanners. Different types of network cables, such as coaxial cable , optical fiber cable , and twisted pair cables, are used depending on the network's topology ...
Internet. Interplanetary Internet. v. t. e. A personal area network ( PAN) is a computer network for interconnecting electronic devices within an individual person's workspace. [ 1] A PAN provides data transmission among devices such as computers, smartphones, tablets and personal digital assistants. PANs can be used for communication among the ...
