A computer network is a group of computers that use a set of common communication protocols over digital interconnections.

Computer Network

Packet

In telecommunications and computer networking, a network packet is a formatted unit of data carried by a packet-switched network.

Local Area Network (LAN)

A local area network is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building.

Wide Area Network (WAN)

A wide area network is a telecommunications network that extends over a large geographic area for the primary purpose of computer networking.

Node

In networking a node is either a connection point, a redistribution point, or a communication endpoint.

Media Access Control (MSC)

The medium access control sublayer is the layer that controls the hardware responsible for interaction with the wired, optical or wireless transmission medium. 

IP Address

An Internet Protocol address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.

Bus Topology

A bus network is a network topology in which nodes are directly connected to a common half-duplex link called a bus.

Ring Topology

A ring network is a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway

Network Token

In networking, a token is a series of bits that circulate on a token-ring network.

Star Topology

A star network is an implementation of a spoke–hub distribution paradigm in computer networks.

Tree Topology

A tree network, or star-bus network, is a hybrid network topology in which star networks are interconnected via bus networks.

Protocol

The official procedure or system of rules governing affairs of state or diplomatic occasions.

Peer-Peer Architecture

A peer-to peer architecture consists of a decentralized network of peers - nodes that are both clients and servers. 

Client/Server Architecture

Client–server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service.

Hubs

The effective center of an activity, region, or network.
