What is bandwidth?
Bandwidth is the amount of data that can be transmitted per second (measured in Mbps or Gbps).
How does bandwidth affect network performance?
Higher bandwidth improves performance because more data can be transmitted at the same time.
What is latency?
Latency is the delay in data transmission, measured in milliseconds.
How does latency affect network performance?
Higher latency slows down responsiveness; lower latency improves performance.
What causes latency?
Distance and network congestion.
What is interference in a network?
Disruption caused by other electronic devices or physical obstacles.
How does interference affect networks?
It weakens signals and reduces network performance.
Give examples of interference.
Thick walls, other wireless devices, electromagnetic interference in cables.
How does the number of connected devices affect performance?
More devices share bandwidth, making the network slower.
How does large data transfer affect performance?
Larger quantities of data take longer to transmit, slowing performance.
How does distance affect network performance?
Greater distance increases transmission time and latency.
What are data collisions?
When two data packets are sent at the same time on the same network and collide.
How do data collisions affect performance?
Data must be resent, which slows down the network.
What is server performance?
How well a server can handle requests and deliver data.
What can cause poor server performance?
Too many users, DDoS attacks, low CPU speed, or limited RAM.
How does poor server performance affect users?
Slow loading times or failure to access websites.
What factors affect network performance?
Bandwidth, latency, interference, number of devices, data size, distance, data collisions, and server performance.
