1. Why is TCP/IP such an important web protocol?
1. It’s fast. It makes sure the data arrives as quickly as possible
2. It’s secure. It makes sure that hackers cannot see the data en route
3. It guarantees delivery. It guarantees that data arrives intact, which creates a duplicate of the original file
4. It reduces redundancy. It doesn’t care if data is lost, such as when streaming a movie.
5. It’s efficient. It uses less resources than UDP.

 

1. How does TCP handle lost data or packets during transit?
1. TCP must initiate a new connection with the server
2. TCP must stop the file transfer and then restart at the beginning of the file
3. TCP knows what packet was lost. So, it will request only the lost packet.
4. TCP is smart enough to know if the packet is important (maybe the file doesn’t need the data)
5. Data packets never go missing.

 

1. What is the role of IP in the TCP/IP internet protocol stack?
1. Creates a virtual connection
2. Carries the data to the final destination
3. Splits the data into small packets
