network device that has power connected to it. It regenerates any signal that is received.
period of time two network stations wait before trying to retransmit data after data packets from the two stations collide.
Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA)
protocol used by wireless networks to control and insure the delivery of data
Carrier Sense Multiple access with Collision Detection (CSMA/CD)
protocol used by ethernet networks to control and insure the delivery of data
a networking model in which the network is made up of computers that are either clients or servers
when a signal crosses from one set of wires to another set that runs directly alongside of it
server with special functions, such as file servers, print servers, database servers, web page servers, and/or administrative servers
a network that communicates by broadcasting information to all computers on the network
device used to provide a quick and easy method of connecting network equipment together by cables
local area network (LAN)
a small network of computers contained in a relatively small area, such as an office building
media access control (MAC) address
a hexadecimal number programmed into the Network card's chip. It is different on every card produced..
a network topology in which each node connects directly to every other node on the network.
metropolitan area network
A group of two or more interconnected LANs operating under a single management. Ofthe encompasses a city-sized geographical area.
Multistation Access Unit
a hub-like device that physically connects computers in a star arrangement while maintaining a ring structure
network interface card (NIC)
connects the network communication media, usually twisted pair copper, to the individual network devices, such as workstations, file servers, and printers
open system interconnect (OSI)
seven-layer reference model that describes how hardware and software should work together to form a network communication system
small unit of data into which larger amounts of data are divided so they can pass efficiently through a network
acts as a connection point in a star topology. Signals transmitted from one computer are passed to all connected computers
network administration model in which all PCs connected together are considered equal
a network topology in which a single cable runs continuously from computer to computer
attached to each packet of data transmitted ensuring that the data will be reassembled in the exact order it was transmitted
powerful computer used to manage network resources and provide services such as security and file sharing
a network device that determines wheter a signal should remain in the isolated section of the network or be passed through the device to other parts of the network
a short binary code generated by network software that is passed along from one computer to the next along a ring topology (and some bus technologies)
wide area network (WAN)
a large number of computers spread over a wide geographical area and under the control of a centrally located administrator
