Question 11

Example of Network Layer

Answer 11

IP

ICMP

Question 12

If you request for data from a webpage and you want to make a connection to it, when the server that you are calling for data to be sent says “ok” to sending the data, what response code does the PC get ?

Answer 12

200

Question 13

What is a feature of TCP which is different to UDP

Answer 13

Error-recovery

Question 14

Same-Layer interaction on different computers

Answer 14

The two computers use a protocol to communicate with the same layer on another computer. The protocol defined by each layer uses a header that is transmitted between the computers to communicate what each computer wants to do. Header information added by a layer of the sending computer is processed by the same layer of the receiving computer

Question 15

Adjacent-layer interaction on the same computer

Answer 15

On a single computer, one layer provides a service to a higher layer. The software of hardware that implements the higher requests that the next lower layer perform the needed function
