Multiple Choice

What is the main difference between Ethernet and Internet as described in the text?

• Ethernet connects devices globally, while Internet connects devices locally.

• Ethernet connects devices in a local area network, while Internet connects users from all over the world in a single massive network.

• Ethernet is wireless, while Internet is wired.

• Ethernet is used for mobile devices only, while Internet is used for computers only.

Multiple Choice
