31. OCR GCSE (J277) 1.3 IP and MAC addressing

William is setting up a local area network (LAN) for his home. Ava asked him about the purpose of a MAC address. What should William explain to Ava?

• It's used to route frames on a local area network

• It's used to identify a host computer on the internet

• It's used to route packets on a wide area network

• It's used to control devices remotely via apps

Alexander, Thomas, and James are setting up a network for their school's computer lab. They are discussing the size of an IPv4 address. How many bits is an IPv4 address they should consider for the network?

• 128 bits

• 64 bits

• 32 bits

• 16 bits

Elsie, Emily, and Rosie are setting up a local network for their school project. They are using IPv4 addresses. What is the range of each number in an IPv4 address they should use?

• 0 to 512

• 0 to 1000

• 0 to 255

• 0 to 127

Anaya, Mia, and Grace are working on a school project about internet protocols. They are discussing why IPv6 was invented. What is the main reason they would find in their research?

• To control devices remotely via apps

• To route frames on a local area network

• To replace the running out of unique static addresses in IPv4

• To identify a host computer on the internet

Grace, Charlie, and Aarav are setting up a network for their school's computer lab. They need to configure the IPv6 addresses for the computers. How many groups of hexadecimal digits will they use in each IPv6 address?

• 10 groups

• 8 groups

• 6 groups

• 4 groups

Priya, James, and Noah are studying for their computer science exam. They come across a question about IP version 6 addresses. They want to know, approximately, how many combinations of IP version 6 addresses are there?

• 340 trillion trillion trillion

• 1 trillion

• 1 billion

• 100 trillion

George is setting up a new network and needs to decide between using IP version 4 and IP version 6. He knows that the size of the address space is a key factor in his decision. Can you help him by telling how many bits an IP version 6 address is?

• 32 bits

• 128 bits

• 64 bits

• 256 bits

Thomas is setting up a new network at his home. He is confused between using IP version 4 and IP version 6. Lily suggests that the main difference between the two is the size of the address. Is Lily correct?

• The type of devices they can connect

• The range of numbers in the address

• The use of colons in the address

• The size of the address

George, Muhammad, and Ishaan are working on a networking project. They are discussing the purpose of the first part of an IP address. George suggests that it is used to identify the network the traffic needs to go to. Is he correct?

• Yes, it is used to identify the network the traffic needs to go to

• No, it is used to identify the specific host device within the network

• No, it is used to control devices remotely via apps

• No, it is used to route frames on a local area network

Benjamin is setting up a home network and he is configuring the IP addresses for all devices. What is the purpose of the second part of an IP address that he is setting up for each device?

• To route frames on Benjamin's local area network

• To control devices remotely via apps in Benjamin's home

• To identify the specific device in Benjamin's network, like Ava's laptop or Evie's tablet

• To identify the network the traffic needs to go to in Benjamin's home
