Osi Layers

1. Complete the review questions:

a. The seventh layer of the OSI model is the ____ layer.

Application

b. Protocols in the ____layer accept data from the Session layer and manage end-to-end

delivery of data.

Transport

c. True or False: The IP (Internet Protocol) operates in the Transport layer.

True

d. True or False: Standards help to ensure interoperability between software and hardware

from different manufacturers.

True

e. True or False: Standards define maximum acceptable performance.

False

2. Create a table showing each layer of the OSI model in the first column and providing a one

paragraph description of that layer in the second column.

3. Add to your table a column showing which pieces of hardware most commonly manage each layer.

4. Add to your table a column showing the protocols employed at each level.

5. Add a column to your table showing how data is built from layer to layer.

OSI Layers

Layer|Description|Manages|Protocals|Data Build|

Physical |The physical layer is the lowest layer and is concerned with the transmission and reception of the unstructured raw bit stream over a physical medium. The physical layer receives data from the data link layer and transmit it to the wire.|IEEE 802IEEE 802.2ISO 2110ISDN|Data Units|From Data LinkTransmission medium then data line.|

Data Link|The data link is the second layer. The data layer handles transfers from network layer and pyhsical layer.|Manages link controlControls the type of media being used.|a) Logical Link Control (LLC) Error correction and flow controlb) Media Access Control (MAC)i. Communicates with the adapter card.|End System to Intermediate System to Intermediate System to End System|

Network Layer|The network layer is needed when two devices are on the same network.Translates logical network address and names to their physical address (e.g. computername ==> MAC address).|Manages network problems such as packet switching, data congestion and...
