Answer:

What Type of Message Is Sent To A Specific Group Of Hosts?

The term “specific group of hosts” generally refers to multicasting or private messaging. Multicast messages are delivered to multiple recipients simultaneously, while private messaging (or group broadcast messaging) is directed to a specific group of recipients.

What Is A Multicast Message?

A multicast message is a type of one-to-many message delivery option where the same message is sent to multiple recipients. It is used to simultaneously deliver messages to a specific group of hosts, such as computers on the same local area network or Internet Protocol (IP) subnet. The message is routed through a “first-hop router” using the Internet Group Management Protocol (IGMP). Once the message reaches the router, it is then duplicated and sent to multiple hosts on the same network.

What Is A Private Message?

A private message, also known as a group broadcast message, is a type of message delivery option where the message is sent to a specific group of people. This is usually done via private messaging services like email, text messaging, or instant messaging applications. Private messages can be sent to individuals or to multiple recipients at once. The primary advantage of private messages is that they provide a secure, private form of communication that cannot be seen or accessed by anyone outside of the intended recipients.

Summary

When sending messages to specific groups of hosts, there are two main types of message delivery options available – multicast and private messages. Multicast messages are sent to multiple hosts simultaneously using a “first-hop router”, while private messages are sent directly to a specific group of people using a private messaging service. Both of these methods provide a secure form of communication that is not visible to anyone outside of the intended recipients.
