This set of Computer Networks Multiple Choice Questions & Answers (MCQs) focuses on “Internet”.

1. The size of an IP address in IPv6 is _________
a) 32 bits
b) 64 bits
c) 128 bits
d) 265 bits

Explanation: The length of an IPv6 address is 128 bits. As a result, IPv6 allows for 2128, or 340 undecillion, addresses. IPv4 has a limit of 4 billion possible addresses, therefore IPv6 would be a perfect backup plan if IPv4 ran out of fresh ones.
2. Internet works on _______
a) packet switching
b) circuit switching
c) both packet switching and circuit switching
d) data switching

Explanation: The internet operates on packet switching as its foundation. Packet switching offers transportation of packets of data across devices over a common network.
3. Which one of the following is not an application layer protocol used in internet?
a) remote procedure call
b) internet relay chat
c) resource reservation protocol
d) local procedure call

Explanation: On the internet, the Resource Reservation Protocol is a transport layer protocol. It is meant to reserve resources required by network layer protocols and works over IPv4 and IPv6.
4. Which protocol assigns IP address to the client connected in the internet?
b) IP
c) RPC

Explanation: Domain Host Control Protocol (DHCP) is an acronym for Domain Host Control Protocol. It is in charge of assigning IP addresses to clients connected to the internet remotely. The DHCP server is the server that performs this function.
5. Which one of the following is not used in media access control?
a) ethernet
b) digital subscriber line
c) fiber distributed data interface
d) packet switching

9. ISP exchanges internet traffic between their networks by __________
a) internet exchange point
b) subscriber end point
c) isp end point

The Internet is a vast network that connects billions of computers and other electronic devices all around the world. You can get nearly any information, communicate with anyone in the globe, and do a lot more with the Internet. All of this is possible by connecting a computer to the Internet, generally known as going online. The Internet is a network of computers that exchange data.
