- Foiled Twisted Pair (FTP) - Shielded Twisted Pair (STP) - Unshielded Twisted Pair (UTP)
Which of the following are ways for transmitting data at the Ethernet level? - Duplex - Multicast - Broadcast - Unicast
- Multicast - Broadcast - Unicast
How many octets are there in a MAC address?
6
Which of these is an example of something that works on the application layer (layer 5 of the five-layer TCP/IP model)? - A browser - An ethernet cable - A router - UDP
A browser
What's a router?
A device that knows how to forward data between independent networks.
What is a cyclical redundancy check?
A mathematical calculation used to ensure that all data arrived intact.
What is a network with only a single device at each end of the link called?
A point to point connection
Which of these allows connections from many devices and inspects the contents of ethernet protocol data? - A cable - A hub - A collision domain - A switch
A switch
What is the fifth later of the TCP/IP Five-layer network model?
Application
What kind of wiring is in cables that communicate in voltage changes that are received by the receiving device as ones and zero?
Copper
Which layer abstracts away the need for any other layers to care about what hardware is in use?
Data Link
What address is used for Ethernet broadcasts?
FF:FF:FF:FF:FF:FF
What is the difference between full duplex and half duplex?
Full duplex allows communications in two directions at the same time; half duplex mean that only one side can communicate at a time.
A LAN uses Category 6 cabling. An issue with a connection results in a network link degradation and only one device can communicate at a time, but information can still go in either direction. What is the connection operating at?
Half Duplex
Which of the following is an example of a network layer ( layer 3 ) protocol in the five-layer TCP/IP) model? - TCP - Ethernet - IP - UDP
IP
What modulation type is used for computer networks?
Line Coding
What does LAN stand for?
Local Area Network
What layer in the TCP/IP model does IP use?
Network
The _____ consists of devices and is responsible for sending signals between devices.
Physical Layer
Fill in the blank: There will almost always be some troubleshooting data available through ____.
Port Lights
Which device forwards data and operates at layer three of the TCP/IP model?
Router
What device provides emails to devices like laptops and desktop computers?
Server
Which of these is a server? - A device that forwards data between multiple networks - Something providing data to something requesting the data - Something receiving data from something providing data - A device operating on the data link layer that connects many devices together and inspects ethernet protocol data.
Something providing data to something requesting the data.
On which later are Ethernet standards and wireless technologies operating?
The Data Link Layer
Which level of the TCP/IP five-layer model does a router operate on?
The Network Layer
Which layer of the five layer TCP/IP model deals with cabling and connectors?
The Physical Layer
Which protocol provides mechanisms ensuring data is reliably delivered?
Transmission Control Protocol (TCP)
True or False: Fiber cables use pulses of light to represent the ones and zeros of data.
True
What is the most common type of cabling used for connecting computing devices?
Twisted Pair Cable
