In computer networking and telecommunications, agateway is a component that is part of two networks, which use different protocols. The gateway will translate one protocol into the other. A router is a special case of a gateway. Gateways, also called protocol converters, can operate at any network layer

In computer networking, a wireless access point (WAP), or more generally just access point (AP), is a networking hardware device that allows a Wi-Fidevice to connect to a wired network.

When referring to a network, a hub is the most basicnetworking device that connects multiple computersor other network devices together. Unlike a networkswitch or router, a network hub has no routing tables or intelligence on where to send information and broadcasts all network data across each connection.

A network device used to regenerate or replicate a signal. Repeaters are used in transmission systems to regenerate analog or digital signals distorted by transmission loss. Analog repeaters frequently can only amplify the signal while digital repeaters can reconstruct a signal to near its original quality.

The Internet is not synonymous with World Wide Web. The Internet is a massive network of networks, a networking infrastructure. It connects millions ofcomputers together globally, forming a network in which any computer can communicate with any othercomputer as long as they are both connected to theInternet.

A Uniform Resource Locator, colloquially termed a web address, is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. A URL is a specific type of Uniform Resource Identifier, although many people use the two terms interchangeably.

The name is sometimes written as WiFi, Wifi, or wifi, but these are not approved by the Wi-Fi Alliance. IEEE is a separate, but related organization and their website has stated "WiFi is a short name for Wireless Fidelity".

When referring to computers, a bridge is a device that connects two LANs (local area networks), or two segments of the same LAN. Unlike a router, bridges are protocol independent. They forward packets without analyzing and re-routing messages

An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocolfor communication. An IP address serves two principal functions: host or network interface identification and location addressing.

A star topology is a topology for a Local Area Network (LAN) in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, only one node will be brought down.

A tree topology is a special type of structure in which many connected elements are arranged like the branches of a tree. For example, tree topologies are frequently used to organize the computers in a corporate network, or the information in a database.

Mesh topology is a type of networking where all nodes cooperate to distribute data amongst each other. Thistopology was originally developed 30+ years ago for military applications, but today, they are typically used for things like home automation, smart HVAC control, and smart buildings

# data[].attributes.body
A bus topology is a topology for a Local Area Network (LAN) in which all the nodes are connected to a single cable. The cable to which the nodes connect is called a "backbone". If the backbone is broken, the entire segment fails.

A ring topology is a network configuration in which device connections create a circular data path. Each networked device is connected to two others, like points on a circle. Together, devices in a ring topology are referred to as a ring network

# data[].attributes.body
The physical topology is the way you physically lay out the network, like a map, and the logical topology is the way the information flows on the network. Usually, the physical and logical topology is the same, but sometimes they can differ, such as in a physical star/logical ring topology.

A communication channel or simply channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel in telecommunications and computer networking.

An organizational structure is a system that outlines how certain activities are directed in order to achieve the goals of an organization. These activities can include rules, roles and responsibilities. The organizational structure also determines how information flows from level to level within the company.

Stands for "Peer to Peer." In a P2P network, the "peers" are computer systems which are connected to each other via the Internet. Files can be shared directly between systems on the network without the need of a central server. In other words, each computer on a P2P network becomes a file server as well as a client.

# data[].attributes.body
client/server network. A computer network in which one centralized, powerful computer (called the server ) is a hub to which many less powerful personal computers or workstations (called clients ) are connected. The clients run programs and access data that are stored on the server. Compare peer-to-peer network .

TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent.

A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN).

A neighborhood area network (NAN) is an offshoot of Wi-Fi hotspots and wireless local area networks (WLAN), which enable users to connect to the Internet quickly and at very little expense. A NAN is generally installed by an individual to serve a family or a number of neighbors. NANs cover only a small number of blocks close to an 802.11 access point. With the help of an omnidirectional antenna, a single access point could cover a radius of more than half a mile. Users who wish to connect to an NAN can then make use of a directional antenna to get an improved signal from the access point.

A wide area network is a telecommunications network or computer network that extends over a large geographical distance/place. Wide area networks are often established with leased telecommunication circuits.

A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link to a server. Typically, a LANencompasses computers and peripherals connected to a server within a distinct geographic area such as an office or a commercial establishment.
