Which of the following is an example of a network layer (layer 3) protocol?
IP, TCP, UDP, Ethernet
IP, or Internet Protocol, is the most common network layer protocol.
What's the difference between a client and a server?
A client requests data, and a server responds to that request.
Which of the following are examples of layers of our five-layer network model? Check all
that apply.

The transport layer,
The presentation layer
The application layer
The physical layer
The transport layer,
The application layer
Which of the following statements accurately describe the differences between a hub
and a switch? Check all that apply.
A hub causes larger collision domains/ a hub is a physical layer device, and a switch is
a data link layer device/ a switch remembers which devices are connected on each
interface, while a hub does not.
What does LAN stand for?
Local area network
What's a router?
a device that knows how to forward data between independent networks.
What is the type of modulation used by twisted pair cable computer networks known
as?
Line coding
What's the difference between full and half duplex?
Full duplex allows communications in two directions at the same time; half duplex
means that only one side can communicate at a time.
How many octets are there in a MAC address?
6; A MAC address is a 48-bit number consisting of 6 octets.
What address is used for Ethernet broadcasts?
FF::FF:FF::FF::FF:FF
What is a cyclical redundancy check?
A mathematical calculation used to ensure that all data arrived intact.; A cyclical
redundancy check ensures that there was no data corruption.
