The Physical Wiring of the Internet

Nora, Mia, and Oliver are discussing the technology used in internet infrastructure. They are curious about fiber optic cables. What are fiber optic cables?

• Cables made of metal that transmit data using magnetic signals.

• Cables made of rubber that transmit data using sound signals.

• Cables made of copper wires that transmit data using electrical signals.

• Cables made of thin strands of glass or plastic that transmit data using light signals.

Maya, Charlotte, and Mason are working on a project to improve their school's internet infrastructure. They are considering using fiber optic cables. What are the advantages of using fiber optic cables in this scenario?

• High data transmission speed.

• Resistance to electromagnetic interference.

• Longer transmission distances.

• All of the above.

David, Aria, and Elijah are setting up a network for their school project. Which type of cable should they use for transmitting data in their telecommunications network?

• They should use twisted pair cables for wireless communication.

• They should use twisted pair cables made of fiber optic material.

• They should use twisted pair cables, a type of copper cable used in telecommunications.

• They should use twisted pair cables for transmitting power.

Avery, Emma, and Liam are discussing the location of the majority of the physical wiring of the internet. Where is it primarily located?

• In Tokyo, Japan

• In underground tunnels

• In nuclear power plants

• Underwater, on the ocean floor

Evelyn and Jackson are setting up a computer network in their school. They are considering using twisted pair cables. What is the main disadvantage of twisted pair cables that Abigail should warn them about?

• They are too expensive.

• They are too heavy.

• They are susceptible to electromagnetic interference.

• They are too long.

William, Mason, and Benjamin are working on a project to improve internet connectivity in their school. They need to choose the right material for the cables. What is the main component of fiber optic cables that they should use?

• Copper.

• Rubber.

• Glass or plastic.

• Metal.

Abigail and Harper are setting up a wireless network at their home. Do they need to use cables for the wireless connection? (if you get this wrong come on)

• Yes

• No

Isla, Evelyn, and Charlotte are working on a school project about wireless technology. They are discussing how wireless cables work. Can you help them understand the concept?

• Wireless cables use invisible wires.

• Wireless cables transmit data through the air using magic.

• Wireless cables are made of special materials that can transmit signals without physical connections.

• Turns binary data into radio waves and transmits it through air

Kai, Isla, and Evelyn are working on a school project about different types of cables. They are currently researching about coaxial cables. Can you help them understand the primary purpose of a coaxial cable?

• Transmitting power to electrical devices.

• Transmitting data in computer networks and cable television systems.

• Transmitting audio signals in speaker systems.

• Transmitting video signals in security camera systems.

Lily, Elijah, and Nora are setting up a home network. They want to connect their devices using Ethernet. Which type of cable should they most commonly use for their Ethernet connections?

• Coaxial cable.

• Fiber optic cable.

• Twisted pair cable.

• Wireless cable.
