Physical Layer
What is a NIC (Network Interface Card)?
What is the most common form of copper cabling?
This type of cabling contains glass at its core.
What is Fiber Optic?
When data travels across the Data Link layer, it is called this.
What is a frame?
This Data Link sublayer looks to see if it can transmit on the connected media.
They Physical layer transmit data as this data unit.
What is bits?
To protect against things like electromagnetic interference, you should use this type of cable.
What is Shielded Twisted Pair?
This type of network media is defined by IEEE standard 802.11.
What is Wi-Fi/wireless?
Name the two sublayers of the Data Link layer.
What are the Logical Link Control and Media Access Control?
The extended start is a form of what topology?
What is LAN topology?
When talking about how fast data travels, this is the unit of measurement used.
What is bandwidth/bits per second?
UTP cables come with this amount of pairs twisted together.
What is 4 pairs?
This type of fiber optic allows for multiple communications at once thanks to multiple LEDs.
What is multimode fiber?
What is physical/MAC address?
This type of connection allows both devices to send and receive simultaneously.
What is full-duplex?
This term is used to describe the speed of data over a given period of time.
What is throughput?
A crossover cable is designed to connect these kind of devices.
What is like devices?
(Computer to computer, router to router, switch to switch)
When creating a wireless network, building materials or even nature can limit this.
What is coverage area?
To indicate the boundaries of the data, these flags are part of the data link frame.
What is Frame Start and Frame Stop?
Hub and spoke networks, along with point to point and full mesh, are this kind of topology.
What are WAN topologies?
Wireless uses this to send data to connected devices.
What is radio waves?
This type of Ethernet cable has matching ends.
What is straight-through?
This device, which can generate wireless interference, can be found in nearly every kitchen in America.
What is microwave oven?
These two addresses always change between each device on the network.
What are Destination and Source MAC addresses?
What is CSMA/CD?
(Carrier Sense Multiple Access/Collision Detection)
