20
Q

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

A

(MAN) Metropolitan area network

21
Q

(MAN) stands for what? pg 268

A

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

22
Q

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

A

Servers
Clients or workstations
Resources

23
Q

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

A

Servers

24
Q

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

A

print servers

25
Q

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

A

Multipurpose server

26
Q

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

A

Dedicated server

27
Q

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

A

Nondedicated servers

28
Q

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

A

client computers

29
Q

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

A

client software

30
Q

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

A

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

31
Q

(NOS) stands for what? pg 272

A

network operating system

32
Q

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

A

(NOS) Network operating system

33
Q

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

A

workgroups

34
Q

Server-based networks are also known as what? pg275

A

Domains

35
Q

There are five primary network topologies? pg 275

A 
Bus
Star
Ring
Mesh
Hybrid
36
Q

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

A

Bus topologies

37
Q

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

A

star topologies

38
Q

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

A

ring topologies

39
Q

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

A

mesh topology

40
Q

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

A

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

41
Q

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

A

Hybrid topolgy

42
Q

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

A
  1. Physical layer
  2. Data link layer
  3. Network layer
  4. Transport layer
  5. Session layer
  6. Presentation layer
  7. Application layer
43
Q

three types fiber-optic connectors. pg 292

A

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