Question 1

Describe the relationship between the service data unit (SDU)and protocol data unit (PDU).

Accepted Answer

At each OSI layer,an SDU is encapsulated with control and transfer information to form a PDU.After the PDU is formed at a particular layer on computer A,for instance,it is then sent to the same layer on computer B.Also,if the layered communications are going down the stack on computer A,for example,then the PDU is sent to the next lower layer in the stack.The control and transfer information is stripped out of the PDU to leave only the SDU.That layer then adds control and transfer information.
