Flashcards in Planning and Cabling Networks Deck (17):
1

Router

Primary device to interconnect networks that breaks up broadcast domains, collision domains and consists of LAN and WAN interfaces

2

To create a LAN...

Connect an end device to a network by using a switch or a hub

3

Vertical cabling

interconnects multiple telecom rooms and equipment rooms, primarily uses fiber optic

4

Horizontal cabling

from telecom room to work area; uses patch cable up to 90 m

5

Work area

locations of end devices for users straight-through most common, can't exceed 100 m

6

Telecom room

connections to intermediary devices such as routers, switches and hubs

7

Factors for considering a switch

Cost: determined by capacity and features
Number and type of ports: UTP or fiber, Mix of UTP speeds or no, Enough for today's needs

8

Factors for choosing a router

Expandability, media, OS features

9

Choosing media

Cost
Bandwidth
Ease of installation
Suspectible to electromagnetic interference or radio frequency interference
Cable length: attenuation increases as cable is longer = signal weakens

10

Straight through characteristics

have same termination at each end
Connects:
switch to router Ethernet port
computer to switch
computer to hub

11

Crossover characteristics

have a T568A at one end T568B on the other end
Connects two like devices and:
computer to router Ethernet port
switch to hub

12

DCE....

provides clocking services to another device (WAN access provider)

13

DTE.....

WAN customer receiving clocking services

14

WAN take a number of forms including....

RJ-11 connectors (telephone, DSL lines)
60 pin serial connections including Smart Serial and Winchester Connector (34-pin female vs. 35 serial cable connector)

15

Console:

primary interface for initialization of a Cisco router or a switch (DB-9 connector, RJ-45 connector)

16

Auxiliary interface

remote management of router modem usually connected for dial-in access

17

Terminal emulator

is used to access network devices via a connection between the device and the computer via a serial interface
