Chapter 1: Introduction To Networks

Front 1

Network

Back 1

Two or more connected computers that can share resources such as data and applications, office machines, an internet connection or some of combination of these

Front 2

Binary code

Back 2

Consist of lots of 1s and 0s in a specific order that describes exactly what they want to "say"

Front 3

Local Area Network (LAN)

Back 3

Usually restricted to spanning a particular geographic location such as an office building, a single department within a corporate office, or even a home office

Front 4

Hub/switch

Back 4

Connectivity devices that allow hosts to physically connect to resources on a LAN

Front 5

Router

Back 5

A connectivity device that can connect two or more LANs together

Front 6

Workstations

Back 6

Powerful computers that run more than one Central Processing Unit (CPU) and whose resources are available to other users on the network to access when needed

Front 7

Client device

Back 7

Any device on the network that can ask for access to resources like a printer or other hosts from the server or powerful Workstation

Front 8

Servers

Back 8

Powerful computers that is truly "at the service" of the network and run specialized software known as the network operating system to maintain and control the network

Front 9

File server

Back 9

Stores and dispenses files

Front 10

Mail server

Back 10

The network's post office; handles email functions

Front 11

Print server

Back 11

Managers printers on the network

Front 12

Web server

Back 12

Manages web-based activities by running Hypertext Transfer Protocol (HTTP) for storing web content and accessing web pages

Front 13

Fax server

Back 13

The "memo maker" that sends and receives paperless faxes over the network

Front 14

Application server

Back 14

Manages network application

Front 15

Telephony server

Back 15

Handles the call center and call routing and can be thought of as a sophisticated network answering machine

Front 16

Proxy server

Back 16

Handles tasks in the place of other machines on the network, particularly an internet connection

Front 17

Host

Back 17

Any network with an IP address

Front 18

Wide Area Network (WAN)

Back 18

Used to span larger geographic areas and truly go the distance

Front 19

Distributed WAN

Back 19

An internetwork that's made up of a lot of interconnected computers located in a lot of different places

Front 20

Centralized WAN

Back 20

Composed of a main, centrally-located computer or location that remote computers and devices can connect to

Front 21

Multiprotocol Label Switching (MPLS)

Back 21

A switching mechanism that imposes labels (numbers) to data and then uses those labels to forward data when it arrives at the MPLS network

Front 22

Peer-to-peer networks

Back 22

Computers connected together that do not have any central, or special, authority; Low security

Front 23

Client-server networks

Back 23

Polar opposite of peer-to-peer networks; a single server uses a network operating system for managing the whole network; high security

Front 24

Bus Topology

Back 24

Consists of two distinct and terminated ends, with each of it's computers connecting to one unbroken cable running it's entire length

Front 25

Star Topology

Back 25

Computers connected to a central point with their own individual cables or wireless connections

Front 26

Ring Topology

Back 26

The network's data flows from computer to computer back to the source, with the network's primary cable forming a ring

Front 27

Mesh Topology

Back 27

A path from every machine to every other one in the network; for each "n" locations or hosts, there are n(n-1)/2

Front 28

Point-to-point Topology

Back 28

A topology that has a direct connection between 2 routers or switches, giving you one communication path

Front 29

Point-to-multipoint Topology

Back 29

A topology that consists of one point of connection to multiple points of connections

Front 30

Hybrid topology

Back 30

A combination of 2 or more types of physical or logical network topologies working together within the same network

Front 31

What should I keep in mind when faced with picking the right topologies for the right network?

Back 31

Cost, ease of installation, ease of maintenance, fault-tolerance requirement and security requirement

Front 32

Network backbone

Back 32

What all the network segments and servers connect to and what gives the network its structure

Front 33

Network segments

Back 33

Any small section of the network that may be connected to, but isn't actually a piece of, the backbone
