Answer:
Layer 4
Explanation:
MAC address works at the data link layer (layer 2) of the OSI model. Mac address allows computers to uniquely identify themselves in the network
IP Address is a logical address that works at the network layer of OSI model (layer 3) (actually the IP layer of TCP/IP model).
The port number works at the transport layer of the OSI model (layer 4).The port number uses sequence number to send segments to the correct application thereby ensuring they arrive in the correct order.
We have information:
3.8 billion 1 second
x billion 0.6 second
To find out the number of operations we need to cross multiply these equations and solve for x.
3.8 * 0.6 = 1*x
x = 2.28 billion
In 0.6s computer can do 2.28 billion operations.
