What is a network?

• A single device connected to the internet
• A group of devices connected to share data
• A type of fiber optic cable
• A wireless connection using radio waves

Answer explanation

A network is a group of devices connected to share data, such as computers, printers, or servers.

True or False: Ethernet is a wireless connection using radio waves.

• True
• False

Answer explanation

Ethernet is a wired connection using copper cables, not a wireless connection.

What does Fiber Optic technology use to transmit data?

• Copper cables
• Radio waves
• Light
• Sound waves

Answer explanation

Fiber Optic technology uses light to transmit data, making it faster than copper-based connections.

Wi-Fi uses which of the following to connect devices?

• Copper cables
• Fiber optic cables
• Radio waves
• Light signals

Answer explanation

Wi-Fi is a wireless connection that uses radio waves to connect devices.

What does the OSI Model represent?

• A type of internet protocol
• A 7-layer framework for how networks work
• A method to assign IP addresses
• A wireless networking standard

Answer explanation

The OSI Model is a 7-layer framework that standardizes how networks function.

Briefly explain the difference between Ethernet and Wi-Fi.

Answer explanation

Ethernet uses physical copper cables for a wired connection, whereas Wi-Fi uses radio waves for a wireless connection.

What is the main advantage of Fiber Optic over Ethernet?

• It is cheaper
• It uses radio waves
• It is faster and light-based
• It doesn't require cables

Answer explanation

Fiber Optic uses light to transmit data, making it faster than Ethernet, which uses copper cables.

True or False: A network can only consist of wired connections.

• True
• False

Answer explanation

A network can include both wired (e.g., Ethernet) and wireless (e.g., Wi-Fi) connections.

Which of the following is NOT a method of connecting devices in a network?

• Ethernet
• Wi-Fi
• Fiber Optic
• Subnet

Answer explanation

Subnet is a division of a network, not a method of connecting devices.
