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