Internetworking Flashcards
What device efficiently breaks up a broadcast domain by default.
Router (Layer 3)
What devices breaks up collision domains by default
Switch (Layer 2)
Term used to describe a network scenario in which one device sends a packet out on a network and every other device is forced to pay attention to it.
Collision Domain
What is used to logically break up broadcast domains in a layer 2 switched network.
VLANs
The OSI Model 7 Layers.
ISO - International Organization Interconnection
Application Presentation Session Transport Network Datalink Physical
OSI layer that provides user interface.
Application
OSI layer that presents data and handles processing such as encryption
Presentation
OSI layer that keeps different applications data seperate
Session
OSI layer - provides reliable or unreliable delivery.
Performs error correction before retransmit
Transport
OSI layer - Provides logical addressing, which routers use for path determination
Network
OSI Layer - Combines packets into bytes and bytes into frames.
Provides access to media using MAC address.
Performs error detection not correction.
Data Link
OSI Layer - Moves bits between devices.
Specifies voltage, wire speed, and pinout of cables
Physical
Session Layer communication modes.
simplex
half-duplex
full-duplex
Solution used to ensure data integrity at the transport layer
flow control: buffering, windowing, and congestion
The two types of packets used at the network layer
data and route update packets
