Flashcards in Chapter 6 Deck (43):
1

Stand-alone computer were insufficient for the following reasons: pg264

small hard- drive capacities
computer required a printer attached locally
sharing documents was cumbersome
there was no email

2

Links two or more computer together to communicate and share resources. pg 264

Network

3

in many cases networking today has become a relatively simple what? pg 264

plug and play process

4

(LAN) stands for what? pg 265

local area networks

5

were introduced to connect computers in a single office or building. pg 265

LAN

6

(WAN) stands for what? pg 265

wide area networks

7

expanded the LAN to include networks outside the local environment and also to distribute resources across long distances. pg 265

WAN

8

(PAN) stands for what? pg 265

personal area network

9

is a very small- scale network designed around one person. pg 265

PAN

10

(MAN) stands for what? pg 265

metropolitan area network

11

is bigger than a LAN but not quite as big as a WAN. pg 265

WAN

12

The 1970s brought us the minicomputer which was a smaller version of the mainframe. Whereas the mainframe used what? pg 265

centralized processing

13

The minicomputer used what kind of processing to access programs across other computer. pg 265

distributed processing

14

The first software programs that ran on a LAN were not capable of being used by more than one user at a time this constraint was known as what? pg 266

file locking

15

(SIG) stands for what? pg 266

Special Interest Group

16

(WPAN) stands for what? pg 267

wireless personal area network

17

The first Bluetooth device on the market was. pg 267

Ericsson headset and cell phone adapter

18

Two or more Piconets can be linked together in a what? pg 268

scatternet

19

A Bluetooth-enabled device can communicate with up to seven other devices in one what? pg 268

Piconet

20

For those networks that are larger than a LAN but confined to a relatively small geographical area there is a term what that? pg 268

(MAN) Metropolitan area network

21

(MAN) stands for what? pg 268

metropolitan area network is generally defined as a network that spans a city or a large campus

22

When you're looking at the devices or resources available on a network there are three types of components to be aware of: pg 268

Servers
Clients or workstations
Resources

23

Offer networks the capability of centralizing the control of resources and security thereby reducing administrative difficulties. pg 269

Servers

24

Servers that host printing services for users are called what? pg 269

print servers

25

Can be for example both a file server and a print server at the same time. pg 269

Multipurpose server

26

Is assigned to provide specific application or services for the network and nothing else. pg 269

Dedicated server

27

Can be used to direct network traffic and perform administrative actions but they also often used to serve as a front-end for the administrator to work with other applications or services or perform services for more than one network. pg 270

Nondedicated servers

28

In network terms workstation are also known as what? pg 270

client computers

29

You must connect it to a cabling system that connects to other computers unless your NIC supports wireless networking. And you must install special software called. pg 270

client software

30

It takes several items to make a workstation into a network client. You must install a what? 270

(NIC) Network interface card a special expansion card that allows the PC to talk on a network.

31

(NOS) stands for what? pg 272

network operating system

32

To control the communication with resources and the flow of data across the network. pg 272

(NOS) Network operating system

33

Peer-to-peer networks are also referred to as what? pg 273

workgroups

34

Server-based networks are also known as what? pg275

Domains

35

There are five primary network topologies? pg 275

Bus
Star
Ring
Mesh
Hybrid

36

Messages pass through the trunk and each workstation checks to see if a message is addressed to itself. pg 276

Bus topologies

37

Branches each network device off a central device called a hub making it easy to add a new workstation. pg 276

star topologies

38

Each computer connects to two other computers joining them in a circle and creating a unidirectional path where messages move from workstation to workstation. pg 277

ring topologies

39

is the most complex in terms of physical design. In this topology each device is connected to every other device. pg 278

mesh topology

40

for this reason the mesh topology is found in WANs to connect multiple sites across WAN links.It uses a device called what? pg 278

Routers to search multiple routes through the mesh and determine the best path.

41

Is simply a mix of the other topologies. It would be impossible to illustrate it because there are many combination.pg 279

Hybrid topolgy

42

what are the five layers of OSI. pg 280-281

1. Physical layer
2. Data link layer
3. Network layer
4. Transport layer
5. Session layer
6. Presentation layer
7. Application layer

43

three types fiber-optic connectors. pg 292

ST) Straight tip
SC) Subscriber connector
LC) Local connector
