A method of communication where packets are sent to every host on the network.

 A model where all computing for a network is done by a large central device.

 A model that distributes applications between servers such as Windows Server 2008 and client computers such as Windows 7 or Windows Vista machines.

 Short for carrier sense multiple access with collision avoidance. It is used as a method for multiple hosts to communicate on a wireless network and AppleTalk.

Short for carrier sense multiple access with collision detection. It is the method for multiple hosts to communicate on a Ethernet.

 When a company’s telephone system meets its computer system. Here, special PBXs that used to control phones as a separate entity can now be controlled by servers with powerful software.

Network speed, also known as bit rate. This is defined as the maximum bits per second (bps) that can be transmitted over a network.

A server that provides data for applications.

Also known as a perimeter network, a small network that is set up separately from a company’s private LAN and the Internet.

A model where computing is provided by each host.

A networking standard that has a set of rules that govern the transmission of data between network adapters and various central connecting devices.

A server that stores files for computers to share

A group of bytes packaged by a network adapter for transmission across the network. 

A type of communication where traffic is sent in both directions at the same time.

A type of communication where traffic is sent in both directions, but only one at a time.

A device or computer has an IP address

A basic central connecting devices (sometimes referred to as CCDs) that connects each of the networked computers, known as hosts, to one another by way of copper-based cables. A hub is considered a legacy device.

A standard that defines carrier sense multiple access with collision detection or CSMA/CD. Because computers on a default Ethernet LAN all share the same channel, CSMA/CD governs the way that computers co-exist with limited collisions.

A logical address that identifies a device or host connected on a network.

local area network (LAN) – A group of these computers that are confined to a small geographic area, usually one building.

A port used to daisy chain or stack one or more hubs or switches.

A topology where every host or server is connected to every other host or server.

Email servers, but also fax, instant messaging, collaborative, and other types of messaging servers. For a Windows Server to control email, special software known as Exchange Server has to be loaded in addition to the operating system.

Microsoft’s firewall and proxy server.

A common tool used for network documentation

A central connecting device usually associated with Token Ring.

Also known as a network interface card or NIC, it is the device that enables you to send and receive data to and from your computer.

A controlling server such as a Microsoft domain controller, it is in charge of user accounts, computer accounts, network time, and the general well-being of an entire domain of computers and users.

Any information that helps describe, define, and otherwise explain how computers are connected in a physical and logical way.

An operating system used by a server to provide network services.

A method that defines the physical connections of hosts in a computer.

A model that has each computer has an equal ability to serve data and to access data, just like any other computer on the network.

Also known as a DMZ, a small network that is set up separately from a company’s private LAN and the Internet.

A server controls printers that can be connected directly to the server or (and more commonly) are connected to the network.

A topology that forms a ring or loop.

A common connector or plug used on the end of the network cable. 

A method where data is sent, one bit at a time.

A topology where each computer is individually wired to a central connecting device with twisted-pair cabling.

A device similar to a hub that connects computers to a central point. However, different from a hub, a switch will only forward traffic to its destination instead of broadcasting.

Transceiver –

A communication method where traffic is only sent to the computer or host that is meant to be sent to.

A group of hosts with a common set of requirements that communicate as if they were connected together with a common set of requirements that communicate as if they were connected together in a normal fashion on one switch, regardless of their physical location.

A server that share data and provide information about a company using HTML web pages..

A central connecting device used in wireless networks.
