Network

A network is defined as a group of two or more computer systems linked together. There are many types of computer networks, including the following: local-area networks [LANs]: The computers are geographically close together [that is, in the same building].

PAN

A personal area network [PAN] is a computer network used for data transmission amongst devices such as computers, telephones, tablets and personal digital assistants.

WAN

A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks [LANs]. Computers connected to a wide-area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites.

LAN

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 LAN encompasses computers and peripherals connected to a server within a distinct geographic area such as an office or a commercial establishment.

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.

Server

A computer or computer program that manages access to a centralized resource or service in a network.

Client

A desktop computer or workstation that is capable of obtaining information and applications from a server.

Peer-to-peer network

In its simplest form, a peer-to-peer [P2P] network is created when two or more PCs are connected and share resources without going through a separate server computer. A P2P network can be an ad hoc connection—a couple of computers connected via a Universal Serial Bus to transfer files.

NIC

A network interface card [NIC] is a circuit board or card that is installed in a computer so that it can be connected to a network. A network interface card provides the computer with a dedicated, full-time connection to a network.

Protocol

A protocol or communication protocol is a set of rules in which computers communicate with each other. The protocol says what part of the conversation comes at which time. It also says how to end the communication.

IP adress

A unique string of numbers separated by periods that identifies each computer using the Internet Protocol to communicate over a network.

Mac adress

A media access control address [MAC address] of a computer is a unique identifier assigned to network interfaces for communications at the data link layer of a network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi.

HUB

A hub is the most basic networking device that connects multiple computers or other network devices together. Unlike a network switch or router, a network hub has no routing tables or intelligence on where to send information and broadcasts all network data across each connection.

Switch

A network switch [also called switching hub, bridging hub, officially MAC bridge] is a computer networking device that connects devices together on a computer network, by using packet switching to receive, process and forward data to the destination device.

Wireless access point

In computer networking, a wireless access point [WAP] is a networking hardware device that allows a Wi-Fi compliant device to connect to a wired network. The WAP usually connects to a router [via a wired network] as a standalone device, but it can also be an integral component of the router itself.

Router

A networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. A data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node.

Wired network

A common type of wired configuration. Most wired networks use Ethernet cables to transfer data between connected PCs. In a small wired network, a single router may be used to connect all the computers. Larger networks often involve multiple routers or switches that connect to each other.

Wireless network

A Wireless networking is a method by which homes, telecommunications networks and enterprise [business] installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations.

Network Topology

A network topology is the pattern in which nodes [i.e., computers, printers, routers or other devices] are connected to a local area network [LAN] or other network via links [e.g., twisted pair copper wire cable or optical fiber cable]. There are four principal topologies used in LANs: bus, ring, star and mesh.

Internet

A huge area on a device or computer where you can do basically anything you want and roam free and find out things, play games, watch videos and learn anything you want to.

Host

A network host is a computer or other device connected to a computer network. A network host may offer information resources, services, and applications to users or other nodes on the network. A network host is a network node that is assigned a network layer host address.

Packet

A network packet is a formatted unit of data carried by a packet-switched network. Computer communications links that do not support packets, such as traditional point-to-point telecommunications links, simply transmit data as a bit stream.

Packet switching

Packet switching describes the type of network in which relatively small units of data called packets are routed through a network based on the destination address contained within each packet. Breaking communication down into packets allows the same data path to be shared among many users in the network.

Virtual network

A virtual network is a computer network that consists, at least in part, of virtual network links. A virtual network link is a link that does not consist of a physical [wired or wireless] connection between two computing devices but is implemented using methods of network virtualization.

Network topology

A network topology is the pattern in which nodes [i.e., computers, printers, routers or other devices] are connected to a local area network [LAN] or other network via links [e.g., twisted pair copper wire cable or optical fiber cable]. There are four principal topologies used in LANs: bus, ring, star and mesh.

Start topology

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.
