A network is a group of computers connected together in a way that allows information to be exchanged between the computers.

Packet-A piece of a message transmitted over a packet-switching network. 

Local area network (LAN) technologies connect many devices that are relatively close to each other, usually in the same building.

Wide area network (WAN) technologies connect a smaller number of devices that can be many kilometers apart.

A node is anything that is connected to the network. While a node is typically a computer, it can also be something like a printer or CD-ROM tower.

Media Access Control (MAC) address - This is the physical address of any device -- such as the NIC in a computer -- on the network. The MAC address, which is made up of two equal parts, is 6 bytes long. The first 3 bytes identify the company that made the NIC. The second 3 bytes are the serial number of the NIC itself.

An IP address is an identifier for a computer or device on a TCP/IP network. 

Bus topology: A network that uses a bus topology has all nodes connected by a common link, called a “bus link.” All data are transmitted and received through the bus line.

Ring topology: nodes are connected in a continuous loop and the packets of data are passed down from one node to the next, usually in a consistent direction.

Network Token-In programming languages, a single element of a programming language. For example, a token could be a keyword, an operator, or a punctuation mark.

Star Topology: All devices are connected to a central hub. Star networks are relatively easy to install and manage, but bottlenecks can occur because all datamust pass through the hub.

tree topology: A 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.

protocol-An agreed-upon format for transmitting data between two devices. 

peer-to-peer architecture- a type of network in which each workstation has equivalent capabilities and responsibilities. Peer-to-peer networks are generally simpler, but they usually do not offer the same performance under heavy loads.

client-server architecture is a network architecture in which each computer or process on the network is either a client or a server.
