Physical
Will OSI Model Layers communicate with different layers Correct
Answer - No, only talk to the same layer on the other device.
Can OSI Layer 2 communicate will layer 5 Correct Answer - No,
OSI Layers can only communicate with layers one above or below.
What is the Purpose of the OSI Model Correct Answer -
Provide a model to describe how data moves from source device to
destination device.
What are the responsibilities of Layer 1 of the OSI Model Correct
Answer - Transmission of bits over medium.
What is the Physical medium that Layer 1 of the OSI model use to
transmit data. Correct Answer - Cables, Connectors, NIC,
Repeaters, and Hubs
What is the Responsibilities of the Data Link Layer. Correct
Answer - For Node to Node delivery & creates frames & Physical
Address ( MAC Address).
, What does the Data Link Layer responsible to control Correct
Answer - Access, Flow, and Error
Describe Transmission Control's function Correct Answer -
Establishing & Terminating, Media Access Management, Flow
Control, Error Control, Access Control.
What does the logical link control (LLC) sublayer of the data link
layer determines? Correct Answer - To use either the
connectionless or connection - oriented.
What are the basic functions of the Network Layer Correct Answer
- Packet Addressing, Address Conversion, Source-to-Destination
Delivery, & Routing.
Does a router determine the best path to destination? Correct
Answer - Yes
Does the Router provide physical or logical connections for the
network Correct Answer - It Provides Logical Address scheme
Packetizing at the network layer involves Correct Answer -
Creates packet from transport layer, encapsulation, and applied IP
address both source and destination.
Fragmentation at the network layer does Correct Answer -
Divides large packets into smaller ones so it can be sent easier.
The responsibilities of the transport layer Correct Answer -
End to end message delivery, error checking, distinguishes
application protocol, and adds port value.
