Connectivity Methods

Question 1

What Is Twisted Pair Cable?

Answer 1

Most common cable often used in telephone systems

Question 2

Advantages Of TPC

Answer 2

Advantages
1. Cheaper and far easier to splice
2. susceptible to electrical interference caused by nearby equipment or wires.
3. In turn are less likely to cause interference themselves
Because it is electrically “cleaner”,
4. STP wire can carry data at a faster speed.

Question 3

Disadvantages Of TPC

Answer 3

Disadvantages

1. STP wire is that it is physically larger and more expensive than twisted pair
2. STP is more difficult to connect to a terminating block.

Question 4

Coaxial Cable Advantages

Answer 4

Advantages
1. Coaxial cable can support greater cable lengths between network devices than twisted pair cable.
2. Thick coaxial cable has an extra protective plastic cover that help keep moisture
away.

Question 5

Disadvantages of Coaxial Cable

Answer 5

Disadvantages

1. Thick Cable
2. coaxial is that it does not bend easily and is difficult to install.

Question 6

Coaxial Definiton

Answer 6

a transmission line that consists of a tube of electrically conducting material surrounding a central conductor held in place by insulators and that is used to transmit telegraph, telephone, television, and Internet signals

Question 7

Coaxial Advantages

Answer 7

1. Easy To Install
2. Small IN DIAMETER
3. Not Much Interference from other things

Question 8

Coaxial Disadvantages

Answer 8

1. If the cable fails the whole network will go down
2. Cost Is High due to the stiffness of the cable
3. Cost Of Maintenance is high

Question 9

What Is Optical Fibre?

Answer 9

a thin flexible fibre with a glass core through which light signals can be sent with very little loss of strength.

Question 10

What 3 things do Lasers Transmit, and is it through air or glass?

Answer 10

1. Data Signal
2. Voice Signal
3. Video Signal

THROUGH AIR! GLASS IS OPTICAL FIBRES!

Question 11

Advantages of Laser Networks

1. No Physical Cables, No Trip Hazard

2. Good Enough Bandwith for office and normal internet browsing

Question 12

Disadvantages Of Laser Networks

Answer 12

1. Interference Can Occur Through Walls
2. Only Supports a limited amount of connections
3. Not good for big businesses

Question 13

What Is Bluetooth?

Answer 13

Bluetooth is a type of wireless technology for sending data over short distances, the chip can be plugged into devices such as computers, digital cameras and smartphones.

Question 14

3 Advantages Of Bluetooth

Answer 14

1. Excellent for short range communication
2. Low power, ideal for battery operation
3. Can use passwords to only allow authorised people to connect

OTHER AD’S;
World-wide standard so all Bluetooth certified devices are compatible

Fully automatic - can auto-sense other Bluetooth devices nearby

Does not require line-of-sight, unlike infrared

Question 15

2 Disadvantages Of Bluetooth

Answer 15

1. Not particularly high bandwidth

2. It is a short range technology

Question 16

3 Advantages Of Satellite communication

Answer 16

1. Available Anywhere
2. No Phone Line Required
3. 5 - 10 X Faster Than “Dial Up”

Question 17

3 Disadvantages Of Satellite Comms

Answer 17

1. Limited Amount Of Download And Upload Speeds
2. Signal is affected by weather
3. High Startup Cost

Question 18

4G Definition?

Answer 18

4G is the fourth generation of broadband cellular network technology, succeeding 3G

Question 19

4G Advantages?

Answer 19

1. Download And Upload Files Upto 10 Times Faster than 3G

2. 4G networks offer complete privacy, security and safety. This is especially beneficial for corporate establishments

Question 20

4G Disadvantages?

Answer 20

1.

4G networks are quite affordable these days, what with pricing schemes being considerably slashed to fit users’ budgets.

Question 21

Infrared Definition?

Answer 21

This infrared beam is used as a method of remotely controlling electronic devices such as televisions.

Question 22

Ad’s Of Infrared

Answer 22

1. High Security as the signal is short range and directional so unlikely to be intercepted
2. Low interference from other devices and so can be used for high quality sound reproduction

Question 23

Dis Of Infrared

Answer 23

Direction of aim, it requires the transmitter and receiver to be exactly aligned for communication

Low bandwidth

Question 24

Microwave Communication Definition?

Answer 24

Microwave Communication Definition of information or energy by microwave radio waves

Question 25

WI-FI advantages?

Answer 25

1. Wi Fi has no wires because it is a wireless technology | 2. Wi Fi is easy to setup

Question 26

Wi Fi Disadvantages?

Answer 26

wifi has poor range when away from the box. When more people connect the speed of the total wifi slows down.

Question 27

Microwave Communication Advantages?

Answer 27

longer bandwidth which allows larger amount of information can be transmitted.

Question 28

Microwave Communication Disadvantages?

Answer 28

- Line-of-sight will be disrupted if any obstacle, such as new buildings, are in the way - Signal absorption by the atmosphere. Microwaves suffer from attenuation due to atmospheric conditions.
