Computer Network

A computer network is a set of computers connected together for the purpose of sharing resources.

Packets

A network packet is a formatted unit of data carried by a packet-switched network. 

Local Area Network

 is a computer network that spans a relatively small area.

Wide Area Network

A wide area network is a telecommunications network or computer network that extends over a large geographical distance. 

Node

A node is a basic unit used in computer science. Nodesare devices or data points on a larger network. Devices such as a personal computer, cell phone, or printer are nodes.

Media Access Control

is a sublayer of the data link layer (DLL) in the seven-layer OSI network reference model.

IP Address

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

Bus Topology

A bus network is a network topology in which nodes are directly connected to a common linear (or branched) 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 for signals through each node - a ring.

Network Token

programming languages, a single element of a programming language.

Star 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.

Tree Topology

combines characteristics of linear bus and star topologies. It consists of groups of star-configured workstations connected to a linear bus backbone cable

Protocal Definition

in computer science, a set of rules or procedures for transmitting data between electronic devices, such as computers.

Peer Peer Architecture

is a commonly used computer networking architecture in which each workstation, or node, has the same capabilities and responsibilities

Client/Server

The client–server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients

Hub

When referring to a network, a hub is the most basic networking device that connects multiple computers or other network devices together.
