Question

Internet is a

• A. Collection of WAN
• B. Network of Networks
• C. Collection of Networks
• D. Collection of identical LAN & MAN

Hint:

The key idea of the Internet is "inter-networking"—connecting different networks together. This is why "Network of Networks" is the perfect definition.

Answer 1

The Correct Option is B

Step 1: Define the Internet. The Internet is a massive, global network that connects billions of computers and other electronic devices. It works by using standard protocols (like TCP/IP) to link together many different types of smaller networks—including private, public, academic, business, and government networks.
Step 2: Evaluate the options.

(A) Collection of WAN: While the internet involves many Wide Area Networks (WANs), this is an incomplete description. It also includes LANs, MANs, etc.
(B) Network of Networks: This is the most accurate and classic definition. It emphasizes that the Internet's primary nature is to interconnect disparate and diverse networks into a single cohesive global system.
(C) Collection of Networks: This is true but less precise than "Network of Networks". The "interconnection" aspect is key.
(D) Collection of identical LAN & MAN: The networks connected to the internet are not identical; they are highly varied.
The best description of the Internet is a "Network of Networks".
