Question 4

disadvantages of wireless access points

Answer 4

less secure
not as stong and reliable as wired connections

Question 5

switch

Answer 5

sends data between computers on a LAN
they segment the network by forwarding traffic to the correct location
they learn which devices are connected and understand how to forward traffic in an intelligent way

Question 8

fibre optic cables

Answer 8

uses light to transmit data
covers a much longer distance and greater bandwidth than copper
the backbone of the internet uses fibre optic cables
higher bandwidth than copper and suffers from less interface

Question 9
