Chapter 6 Flashcards
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
Links two or more computer together to communicate and share resources. pg 264
Network
in many cases networking today has become a relatively simple what? pg 264
plug and play process
(LAN) stands for what? pg 265
local area networks
were introduced to connect computers in a single office or building. pg 265
LAN
(WAN) stands for what? pg 265
wide area networks
expanded the LAN to include networks outside the local environment and also to distribute resources across long distances. pg 265
WAN
(PAN) stands for what? pg 265
personal area network
is a very small- scale network designed around one person. pg 265
PAN
(MAN) stands for what? pg 265
metropolitan area network
is bigger than a LAN but not quite as big as a WAN. pg 265
WAN
The 1970s brought us the minicomputer which was a smaller version of the mainframe. Whereas the mainframe used what? pg 265
centralized processing
The minicomputer used what kind of processing to access programs across other computer. pg 265
distributed processing
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
(SIG) stands for what? pg 266
Special Interest Group
(WPAN) stands for what? pg 267
wireless personal area network
The first Bluetooth device on the market was. pg 267
Ericsson headset and cell phone adapter
Two or more Piconets can be linked together in a what? pg 268
scatternet
A Bluetooth-enabled device can communicate with up to seven other devices in one what? pg 268
Piconet
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
(MAN) stands for what? pg 268
metropolitan area network is generally defined as a network that spans a city or a large campus
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
Offer networks the capability of centralizing the control of resources and security thereby reducing administrative difficulties. pg 269
Servers
Servers that host printing services for users are called what? pg 269
print servers
Can be for example both a file server and a print server at the same time. pg 269
Multipurpose server
Is assigned to provide specific application or services for the network and nothing else. pg 269
Dedicated server
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
In network terms workstation are also known as what? pg 270
client computers
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
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.
(NOS) stands for what? pg 272
network operating system
To control the communication with resources and the flow of data across the network. pg 272
(NOS) Network operating system
Peer-to-peer networks are also referred to as what? pg 273
workgroups
Server-based networks are also known as what? pg275
Domains
There are five primary network topologies? pg 275
Bus Star Ring Mesh Hybrid
Messages pass through the trunk and each workstation checks to see if a message is addressed to itself. pg 276
Bus topologies
Branches each network device off a central device called a hub making it easy to add a new workstation. pg 276
star topologies
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
is the most complex in terms of physical design. In this topology each device is connected to every other device. pg 278
mesh topology
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.
Is simply a mix of the other topologies. It would be impossible to illustrate it because there are many combination.pg 279
Hybrid topolgy
what are the five layers of OSI. pg 280-281
- Physical layer
- Data link layer
- Network layer
- Transport layer
- Session layer
- Presentation layer
- Application layer
three types fiber-optic connectors. pg 292
ST) Straight tip
SC) Subscriber connector
LC) Local connector
