Q

copper cables

A

cheaper type of wired connections,

poorly insulated, therefore susceptible to magnetic interference

more likely to suffer from attenuation

malleable , less likely to break

lower bandwidth , cant transmit as much data s once then fibre optic cables

Q

fibre optic cables

A

very fast but expensive

signals transmitted through waves of light through a glass tube , therefore not affected by electromagnetic attenuation and suffer less from attenuation

higher bandwidth

fragile

Q

microwave

A

large area via microwave towers

must be in line of sight with each other with no obstructions

are affected by bad weather leading to higher chances of attenuation

Q

satellite

A

use point to point communication by using satellites above the earths atmosphere

long distances causes a delay between transmission

Q

connection characteristics

A

strength / range / latency / bandwidth / storage capacity / contention

latency is the delay when sending data

bandwidth is the maximum amount of data that can be sent across a network at once

contention refers to whether a network is dedicated (uncontended ) or shared between users (contented)
