| Q1: | What is the principle advantage of TCP/IP's modular design? |
|
A1:
| Because of TCP/IP's modular design, the TCP/IP protocol stack can adapt easily to specific hardware and operating environments. |
| Q2: | What functions are provided at the Network Access layer? |
|
A2:
| The Network Access layer provides services related to the specific physical network. These services include preparing, transmitting, and receiving the frame over a particular transmission medium, such as ethernet. |
| Q3: | Which OSI layer corresponds to the TCP/IP Internet layer? |
|
A3:
| TCP/IP's Internet layer corresponds to the OSI Network layer. |
| Q4: | Why is header information enclosed at each layer of the TCP/IP protocol stack? |
|
A4:
| Because each protocol layer on the receiving machine needs different information to process the incoming data, each layer on the sending machine encloses header information. |
