What is the Internet?

• A. A worldwide connected system of computer networks
• B. A Local Area Network (LAN)
• C. A plug-in device used to store information
• D. The set of programs that tell a computer what to do

Answer: (A)

Think of the Internet as a vast, global web of networks that are all tied together. Each separate network—like those in homes, schools, and companies—connects to others using common rules, or protocols (such as TCP/IP), so data can travel from any device to any other across the world. This shared infrastructure enables services like email, web pages, and video streams to work no matter where you are or which organization operates the networks you use. It’s the broader platform that those services ride on.

It’s not a Local Area Network, which is just a small group of devices in a limited area. It’s not a plug-in device used to store information, which would be a storage hardware like a USB drive. It’s also not the set of programs that tell a computer what to do, which describes software or an operating system.
