the internet

• What is the internet described as in the video?

  A network of interconnected networks
• What is a network?

  A group of devices that communicate
• What is the internet protocol suite commonly known as?

  TCP/IP
• What are some properties that apply to any network connection?

  Latency, range, strength, bandwidth, contention
• What does low latency indicate about a network?

  Less delay in getting a response
• What does the range of a network refer to?

  How far away you can be and still connect
• How does network strength relate to range?

  Low strength means unreliable connections at distance
• What does bandwidth measure in a network?

  Data transferred across the network at once
• How do latency and bandwidth relate to network speed?

  Both affect how quickly data is transferred
• What does contention in a network refer to?

  How many devices can use the network simultaneously
• What is an uncontended network?

  A network with only one user connected
• What is commonly used in wired connections for the internet?

  Copper cables
• Why is copper used in ethernet cables?

  It is cheap and transmits electricity well
• What is optical fiber used for?

  Transmitting data using pulses of light
• What are the advantages of optical fiber over copper?

  Higher bandwidth, lower latency, greater range
• What is a disadvantage of optical fiber?

  It can break easily
• What do 4G and 5G networks provide?

  Mobile data access to the internet
• How does 5G compare to 4G?

  5G has lower latency and higher bandwidth
• What is a limitation of 5G coverage?

  It has a much lower range than 4G
• What is the primary use of Wi-Fi?

  Connecting devices wirelessly over a larger range
• How does Bluetooth differ from Wi-Fi?

  Bluetooth connects devices nearby, Wi-Fi has a larger range
• What is a disadvantage of using multiple devices on a network?

  It can lead to contention and errors
• What is a satellite network?

  A network providing signals from space
• What is a disadvantage of satellite networks?

  They have high latency due to distance
• What is a microwave network?

  A network requiring line of sight for connection
• What is a pro of microwave networks?

  They have very high bandwidth
• What affects the strength of a microwave network?

  Line of sight between devices
