Wired & Wireless Networks

Question 1

What are three types of transmission media?

Answer 1

Ethernet cables - fast and reliable connections typically used on LAN to transfer data between nodes and hardware. Ext Cat5e , Cat6

Coaxial cables - older, slower copper cables that have a plastic layer surrounding it to prevent interference.

Fibre optic cable - fast,expensive and fragile cables that transmit data as light they don’t suffer interference allowing them to transfer data along a WAN.

Question 2

What are the effects of using Ethernet?(3)

Answer 2

Restricted movement(1) faster speed(1) prevents interception making it secure(1)
NIC required(1) expensive (1)

Question 3

Name two wireless connection methods(2)

Answer 3

Wi-Fi(1) Bluetooth(1)

Question 4

Name a wired mode of connection

Answer 4

Ethernet(1)

Question 5

Compare Bluetooth and Wi-Fi

Answer 5

Bluetooth is shared connection between two devices and have a lower connection range and bandwidth compared to Wi-Fin.

Wi-Fi is multiple devices connected to a LAN at the same time. They have a larger range and higher bandwidth then Bluetooth. A WAP is needed to connect to Wi-Fi

Question 6

How does a higher Bandwidth affect the performance of a Network

Answer 6

Bandwidth is the amount of data that can be transferred in a given time. The greater the bandwidth the more data that can be transferred and the better the network can perform.

However this could cause congestion slowing down the network
