Technical Terms - Internet (A-Z) - Multicast

What is the main difference between multicasting and broadcasting?

• Multicasting transmits data to specific users, while broadcasting transmits data to all users

• Multicasting transmits data to all users, while broadcasting transmits data to specific users

• Multicasting is more efficient than broadcasting

• Multicasting is less efficient than broadcasting

How does multicasting reduce the required bandwidth compared to individual data transmission?

• By transmitting individual copies of the data to each user

• By creating multicast trees at routers

• By splitting a single transmission among multiple users

• By sending multiple copies of the data to each user

What are IP multicasts known for?

• Creating multicast trees

• Requesting access to a stream

• Using the Internet protocol to transmit data

• Branching out a single transmission to individual users

Which protocol allows users to request access to a stream in IP multicasting?

• Transmission Control Protocol (TCP)

• Internet protocol (IP)

• Protocol Independent Multicast (PIM)

• Internet Group Management Protocol (IGMP)

What is one of the applications of multicasting mentioned in the text?

• Streaming media over the Internet

• Sending emails

• Creating websites

• Developing mobile apps

How does multicasting help reduce Internet bandwidth usage?

• By using the Transmission Control Protocol (TCP)

• By creating branches at routers

• By providing an efficient way of sending data to multiple users

• By increasing the number of data copies sent

What is the purpose of the Internet Group Management Protocol (IGMP) in IP multicasting?

• To create multicast trees

• To transmit data to specific users

• To route the data stream to the appropriate system

• To allow users to request access to a stream

Where are branches created in IP multicasting?

• At the destination system

• Close to the original source

• At the Internet service provider

• At the user's device

What is the role of Protocol Independent Multicast (PIM) in IP multicasting?

• To transmit data to specific users

• To route the data stream to the appropriate system

• To create multicast trees

• To allow users to request access to a stream

Which type of data can be sent over the Internet using multicasting?

• News, stock quotes, and software copies

• Videos only

• Images only

• Text messages only
