Cards

Term
8P8C
Definition
A common connector or plug used on the end of the network cable. Also known as RJ-45.
Term
Broadcast –
Definition

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

Term
centralized computing –
Definition

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

Term
client-server –
Definition

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

Term
CSMA/CA –
Definition

 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.

Term
CSMA/CD –
Definition

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

Term
computer telephony integration (CTI) -
Definition

 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.

Term
CTI-based server -
Definition

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.

Term
data transfer rate –
Definition

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

Term
database server -
Definition

A server that provides data for applications.

Term
demilitarized zone (DMZ) -
Definition

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

Term
distributive computing –
Definition

A model where computing is provided by each host.

Term
Ethernet –
Definition

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

Term
file server –
Definition

A server that stores files for computers to share

Term
frames –
Definition

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

Term
full duplex –
Definition

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

Term
half duplex –
Definition

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

Term
host –
Definition

A device or computer has an IP address

Term
hub -
Definition

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.

Term
IEEE 802.3 –
Definition

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.

Term
IP address –
Definition

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

Term
local area network (LAN) –
Definition

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

Term
medium dependent interface (MDI) –
Definition

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

Term
mesh topology –
Definition

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

Term
messaging server -
Definition

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.

Term
Microsoft ISA Server –
Definition

Microsoft’s firewall and proxy server.

Term
Microsoft Visio -
Definition

A common tool used for network documentation

Term
multistation access unit (MAU) –
Definition

A central connecting device usually associated with Token Ring.

Term
network adapter -
Definition

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.

Term
network controller –
Definition

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.

Term
network documentation -
Definition

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

Term
network operating systems –
Definition

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

Term
network topology –
Definition

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

Term
peer-to-peer (P2P) –
Definition

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.

Term
perimeter network -
Definition

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

Term
print server  -
Definition

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

Term
ring topology –
Definition

A topology that forms a ring or loop.

Term
RJ45 –
Definition

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

Term
serial data transfer –
Definition

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

Term
star topology –
Definition

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

Term
switch –
Definition

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.

Term

Transceiver

Definition
A device or component that can transmit and receive data.
Term
unicast –
Definition

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

Term
virtual LAN (VLAN) –
Definition

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.

Term
