Question 1

copper cables

Answer 1

cheaper type of wired internet

more likely to suffer from attenuation

malleable and less likely to break

lower bandwith

Question 2

fibre optic cables

Answer 2

very fast but expensive

signals are transmitted by waves of light through a glass tube

because of this they do not suffer by electromagnetic interference and less from attenuation
higher bandwidth can transfer more data at a time

more fragile

Question 3

infrared

Answer 3

requires devices to be in direct line of sight

remote controls

short distance

Question 4

microwave

Answer 4

use radio waves to send signals across a large area

must be in line of sight of each other

affected by bad weather

higher chances of network attentiation

Question 5

laser

Answer 5

sends data between devices in line of sight as long as their are no barries

transmit data up to 2km but bad weather severely affects the transmission rate

can be used in space since there are fewer barriers

Question 6

satellite

Answer 6

use point to point multipoint communication

distance around 45kkm

delay between data transmission

Question 7

gsm/5g

Answer 7

GSM( global system for mobile communicatoins) allowing mobile phones to connect to a network for calls and text messages
