What is a characteristic of multicast messages? They are sent to a select group of hosts. They are sent to all hosts on a network. They must be acknowledged. They are sent to a single destination.

They are sent to a select group of hosts

Which statement is correct about network protocols? Network protocols define the type of hardware that is used and how it is mounted in racks. They define how messages are exchanged between the source and the destination. They all function in the network access layer of TCP/IP. They are only required for exchange of messages between devices on remote networks.

They define how messages are exchanged between the source and the destination.

What is an advantage of network devices using open standard protocols? Network communications is confined to data transfers between devices from the same vendor. A client host and a server running different operating systems can successfully exchange data. Internet access can be controlled by a single ISP in each market. Competition and innovation are limited to specific types of products.
