Cabling and Topology

Question 1

Bus Topology

Answer 1

Network that uses single cable to connect all computers in a line

Question 2

Ring Topology

Answer 2

Network that uses single cable to connect all computers on a network in a ring of cable

Question 3

Data Flow of Bus Topology

Answer 3

Data from each computer went out on the whole bus and needed terminations at each end to prevent reflection of signal causing network loss

Question 4

Data Flow of Ring Topology

Answer 4

Data moved in a circle from one computer to the next in the same direction and required no termination.

Question 5

Flaws of Ring and Bus Topology

Answer 5

If the cable broke at any point the whole network would go down.

Question 6

Star Topology

Answer 6

Uses central connection box for all the computers on the network which offers Fault tolerance.

Question 7

Hybrid Topology

Answer 7

A bus or ring network that has been shrunken down into a box that uses physical topology and logical topology.

Question 8

Physical Topology

Answer 8

How the cables physically look

Question 9

Logical Topology

Answer 9

How the Signals Travel electronically

Question 10

Mesh Topology

Answer 10

Every computer can connect to every other computer via two or more route.

Question 11

Partially Meshed Topology

Answer 11

At least two machines have redundant connections. Every machine doesn’t have to connect to every other machine.

Question 12

Fully Meshed Topology

Answer 12

Every computer connects directly to every other computer.

Question 17

2 Coaxial Cable T ypes

Answer 17

RG-59 and RG-6

Question 18

RG-59 Coaxial Cable

Answer 18

Used primarily for cable tv, rated at 75 OhMs and had F type connector

Question 19

RG-6 Coaxial Cable

Answer 19

Much thinner style coax that is mainly used today, rated at 75 Ohms and uses F type connector

Question 20

RG

Answer 20

Radio Guide Rating that measure OhM

Question 21

RG-58

Answer 21

Used primarily for Television rated at 50 OhMs and had BNC Connector

Question 22

Twisted Pair Cable

Answer 22

Consists of twisted pairs of cables bundled together into a common jacket.

Question 23

2 Types of twisted pair cables

Answer 23

Shielded and Unshielded

Question 24

STP

Answer 24

Shielded twisted pair cable consists of twisted wires surrounded by shielding to protect from EMI.

Question 25

UTP

Answer 25

Unshielded Twisted pair cable consists of twisted pairs of wires surrounded by plastic jacket. UTP offers no protection from surrounding EMI.

Answer 28

100 MHz, 1 Gbps

Question 29

Cat6

Answer 29

250 MHz, 10 Gbps

Question 30

Question 32

RJ-11 Connector

Answer 32

Use by landline telephones and had 8 Positions and 8 Contact connectors.

Question 33

RJ-45 Connector

Answer 33

UTP connection for standard networking used today

Question 34

Most Common Fiber Optic Cable Size

Answer 34

62,5/125 Micro um

Question 35

MMF

Answer 35

Multimode Fiber, uses LED's

Question 36

SMF

Answer 36

Single Mode Fiber, Uses lasers

Question 37

Modal Distortion

Answer 37

Affects only Multimode Fiber, signals sent at the same time don't arrive at the same time because the paths differ slightly in length.

Question 38

Transmit wavelength of MMF

Answer 38

850-nm

Question 39

Transmit wavelength of SMF

Answer 39

1310 nm or 1550nm depending on laser

Question 40

4 Types of Fiber Connectors

Answer 40

ST, SC, LC and MT-RJ

Question 41

Serial Cables

Answer 41

Used in early networking for point to point connections, had speeds up to 56,000 bps and used DB-9, 9 pin connector

Question 42

Parallel Cables

Answer 42

Used in early networking for point to point connections, had speeds up to 2 Mbps and used 25 pin female DB-25 Connector

Question 43

PVC Rated Cable

Answer 43

Has no protection from Fire and will create lots of smoke and fumes

Question 44

Plenum Rated Cable

Answer 44

Create much less smoke and fumes than PVC cabling but costs a lot more
