Network 3.1 - Protocols

UDP (User Datagram Protocol) is used when...

• Data accuracy is the most important

• Transmission speed is the priority

• A balance of transmission speed and data accuracy is needed

Like TCP, UDP can

• Detect errors

• Correct errors

• Reassemble packets into the correct order

One advantage of TCP compared to UDP is that it can _______ errors

Select one answer.

A network protocol is ...

• a unique identifier that is assigned to network interface cards by the NICs manufacturers.

• is a set of rules

The Ethernet protocols are ...

• a collection of protocols that work together to allow commutation across the internet and other networks

• a family of protocols used to connect devices together across  Local Area and Wide Area Networks

What does the Ethernet family of protocols contain?

• The rules for transmitting information using TCP.

• The rules for communicating across different types of transmission media and the use of MAC addresses

• Internet protocol

MAC address is ...
