Question 1

True or false: The World Wide Web and the internet are the same thing.

Accepted Answer

False. The internet is the network of protocols (like TCP/IP); the Web is an application (HTTP/HTML) that runs on it.

Question 2

True or false: Vint Cerf and Bob Kahn wrote the first email protocol.

Accepted Answer

False. Vint Cerf and Bob Kahn invented TCP/IP, the foundational protocols of the internet. The first email system was created by Ray Tomlinson in 1971, who introduced the '@' symbol for addressing, predating their work.

Question 3

True or false: UDP was invented as a lightweight alternative to TCP for streaming audio.

Accepted Answer

False. UDP was created in 1980 for simple, fast datagram delivery, not specifically for streaming—that came later.

Question 4

True or false: IPv6 was invented because the internet ran out of IPv4 addresses in the 1990s.

Accepted Answer

False. IPv6 was designed in the 1990s anticipating exhaustion, but IPv4 didn't fully run out until 2011, and workarounds delayed crisis.

Question 5

True or false: TCP/IP was originally developed for the US Department of Defense.

Accepted Answer

True. TCP/IP was created in the 1970s for ARPANET, a DoD project, to enable robust, decentralized communication.

Question 6

True or false: The 'Internet Protocol' was originally called the 'Catenet Model'.

Accepted Answer

False. The term 'Catenet' described a model for interconnected networks, not the Internet Protocol. IP has always been called the Internet Protocol (e.g., in RFC 791).

Question 7

True or false: ARPANET's transition to the TCP/IP protocol involved a 'flag day' on January 1, 1983, where all connected computers were required to switch simultaneously.

Accepted Answer

True. To prevent network fragmentation, ARPANET mandated that all hosts switch from NCP to TCP/IP on January 1, 1983, a one-time event known as a 'flag day'.

Question 8

True or false: The first RFC for the Internet Protocol was published in 1981.

Accepted Answer

False. The first RFC for the Internet Protocol was actually RFC 760, published in January 1980. RFC 791 (1981) was a revision.
