Networking

Question 1

UTP

Answer 1

Unshielded twisted pair
Predominately used today
Specified for 100/1000BASE-T
Also 10GBASE-T
AWG 22-26 gauge copper wire twisted together in color coded pairs
Each pair individually insulated

Question 2

TIA

Answer 2

Telecommunication industry association
Establishes UTP categories

ANSI

Answer 3

American national standards institute

Question 4

Category standards

Answer 4

Cat 1: standard phone line
Cat 3: 10mbps networks
Cat 5: 100mbps networks
Cat 5e: 1gbps and 2.5gbps networks at 100 meter segments
Cat 6: 1, 2.5, and 5gbps networks at 100 meter segments
10gbps networks at 55 meter segments
Cat 6a: 10 gbps networks at 100 meter segments

Question 5

STP

Answer 5

Shielded twisted pair
Twisted pairs of wires surrounded by shielding
Protects from electromagnetic interference (EMI)
Some rated for direct burial for use underground or outdoor open air use

Question 6

RJ connectors

Answer 6

Registered jack 11 (RJ-11): connects traditional telephone to telephone jack in wall
- supports up to two pairs of wires, most only use one

Question 10

Fiber optic cable

Answer 10

Uses light instead of electricity
Either LED lights or laser light
2000 meters or more
62.5/125 multimode fiber optic cable

Question 11

Fiber optic connectors

Answer 11

Straight tip (ST): round connector
Subscriber connector (SC): square shaped connector
Lucent connector (LC): two cables in one connector

Question 12

Coaxial

Answer 12

For cable modems and satellite connections
Consists of center cable (core) surrounded by insulation
Then covered with a shield of braided cable, surrounded by protective insulating over

Question 13

Coax ratings

Answer 13

RG-59 (thinner, doesn’t carry data quite as far as RG-6)
RG-6
Both 75ohms impedance
Uses F-type connector

LAN

Answer 14

Local area network
Group of networked computers close to each other
Almost always broadcast domain
