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 physical 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.
