Which statements correctly identify the role of intermediary devices in the network?

Early data networks were limited to exchanging character-based information between connected computer systems. Current networks have evolved to carry...

voice, video streams, text, graphics

The four elements of a network are

Rules, Medium, Messages, Devices

The rules that network devices use to communicated with each other are called:

The most common device for interconnecting local area networks is a:

Internal factors affecting the successful communication across the network include: 1) The size of the message, 2) the complexity of the message, and 3)the importance of the message:

A platform where the flow of voice, video, and data is traveling over the same network is called a:

A characteristic of a network, where if one link or path fails, processes ensure that messages can be instantly routed over a different link transparent to the users on either end is known as its:

Characteristic of a network which prioritize which types of data packets must be delivered at the expense of other types of packets that can be delayed or dropped.

The premise for this type of network is that a single message can be broken into multiple message blocks, these message blocks, called packets, can be sent through the network along various paths, and can be reassembled into the original message upon reaching their destination. 

Packet Switched Connectionless Networks

This means for the ability of the network to expand quickly to support new users and applications without impacting the performance of the service being delivered to existing users. 

The element of a network that must be converted to bits, binary coded digital signals, before being sent to their destination.

Which statements correctly identify the role of intermediary devices in the network?

*determine pathways for data. *retime and retransmit data signals. *manage data flows.

Select the statements that are correct concerning network protocols.

*define the structure of layer specific PDU's. *Outline the functions necessary for communications between layers. *Require layer dependent encapsulations.
