What is the Internet?

What is the Internet?

• A. A single network
• B. A network of networks
• C. A private intranet
• D. A device that routes packets

Answer: (B)

At its heart, the Internet is a network of networks: a global collection of interconnected computer networks that communicate using a common set of rules (TCP/IP). This structure lets devices on different networks send data to each other by hopping across routers and gateways, with data broken into packets that travel through multiple networks to reach their destination. It isn't a single network owned by one organization, nor is it a private intranet limited to a single site. It's also not a single device; routers and other hardware are the building blocks, but the Internet as a whole is the way many networks connect and agree on how to send data.
