1.4 - Network performance factors

What happens when everyone in your house connects to your wireless access point/router with wi-fi enabled devices?

• The network becomes faster.
• The performance is not affected.
• The network becomes slower.

Define the term 'bandwidth'?

• Speed at which data is transferred over a network
• Ratio of users compared to available bandwidth

Which is the fastest cable in a wired network

• Twisted pair
• Cat-5
• Cat-5
  Cat 6
• Fibre optic

When does ethernet signal degradation occur?

• When long cables are used this  means the signal decays over a long distance.
• Nothing happens to signal degradation.

What happens when there is limited bandwidth due to lots of people connecting to the internet at the same time?

• Internet connection slows down
• Internet connection gets faster

Define the term 'wi-fi'.

• When two or more LANs are connected together over a wide area.
• A form of Internet access that uses the facilities of the public switched telephone network (PSTN) to establish a connection to an Internet service provider (ISP) by dialing a telephone number on a conventional telephone line.
• The name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections.
• A local or restricted communications network, especially a private network created using World Wide Web software.

When does radio interference occur on a wireless network?

• Wi-fi signals have a maximum range, with 5GHz signals having a shorter range than 2.4GHz signals.
• If something else is transmitting on the same frequency as a wi-fi network, like a microwave or a faulty electric motor, this lowers the performance of any wi-fi devices trying to communicate on that frequency.

What can physically block a wi-fi signal?

• Solid brick walls
• Signals get weaker over large distances

If you walk away from a wireless access point whilst surfing the internet on your tablet - what will happen to your internet speed?

• The internet connection will be quicker, the greater the distance from the WAP you are.
• The internet connection  will be slower as the signal gets weaker, the further away from the WAP you are

Wireless signals are the same strength at any distance

• True
• False
