Architecture
OSI Model
Addressing
Network to Network
100
End devices on a network like printers and workstations
What is a node
100
Each node is directly connected to the next in this topology
What is bus
100
Layer 1
What is physical
100
Physical address
What is MAC address
100
The point where ISP communication devices and a company's devices are joined
What is demarcation
200
A high-speed networking link connecting only segments
What is a backbone
200
In this network, there are no collisions
What is token ring
200
Web browsers operate at this layer
What is layer 7, application
200
128-bit logical address
What is IPv6
200
Main cross-connect
What is MDF (Main distribution frame)
300
Relatively inexpensive, they have 4 pairs of wires and are the most common network media in LANs
What is UTP
300
This is the channel access method for wireless devices
What is CSMA/CA
300
NICs operate at these layers
What are layers 1 and 2, physical and data-link
300
Identifies a program running on a computer
What is a port address
300
These cables run form the wall jack to a termination block or patch panel
What is drop cable
400
Commonly terminated with a RS-232 connector, they can directly connect two workstations
What is a serial cable
400
In CSMA/CD, this is sent after a collision occurs
What is a jamming signal
400
Uses IP address
What is network layer, layer 3
400
This resolves host names to IP addresses on TCP/IP networks
What is DNS
400
This connects the main cross connect to each floor
What is IDF (Intermediary distribution frames)
500
These are not susceptible to EMI and have the highest bandwidth among the wired media
What is fiber optic
500
This connection has 24 channels carrying 64Kbps each and is a popular choice for WAN connections.
