factors that affect performance

• What is bandwidth in computer networks?

  The amount of data sent in a time period
• How is bandwidth measured?

  In bits per second, or bit rate
• What happens when there are too many users on a network?

  The network can slow down due to insufficient bandwidth
• Which type of connection offers higher bandwidth?

  Wired connections
• Which type of cable offers higher bandwidth, fibre optic or copper?

  Fibre optic cables
• What does a higher error rate indicate about a connection?

  It is less reliable and has more data transfer errors
• What must happen if data is transferred with errors?

  The data must be resent until correct
• What factors affect the quality of a wireless connection?

  Distance from the access point and environmental factors
• What determines the quality of copper cables?

  The grade of the material used
• How does cable length affect network performance?

  Longer cables can reduce signal quality
• What is latency in network performance?

  The delay between data transmission and reception
• What causes latency in a network?

  Bottlenecks in network infrastructure
• How can switches affect network latency?

  Not using switches can cause traffic bottlenecks
• What can affect the speed of various hardware in a network?

  Different speeds of switches and cables
