Question
RUE or FALSE
1. TCP ensures error free transmission.
2. The process that initiates the communication is the server.
3. A host can serve as both server and client in a P2P network.
4. Audio and video applications cannot tolerate errors in data.
5. Audio and video applications demand timely reception of data.
6. Non–persistent TCP connection takes more time for data transfer (compared to a persistent connection)
7. In HTTP, both control information and data are sent on different connections.
8. In FTP, both control information and data are sent on the same connection.
9. The data in a HTTP response from a server to a client could never be empty.
10. A mail server can act as both a client and a server.
11. The Client–Server model is well suited for large file distribution among a large number of users.
Explanation / Answer
1. True
TCP has error correction mechanisms and the data stream control techniques. This ensures that the data is error free.
2. False.
Three way handshake is used in TCP communication.
The server must first open a port and must bind to it and start listening to the port called passive open.
Once this is done by the server, the client will initiate an active open by sending appropriate packets. The communication is initiated by the client always.
3. True
A host can serve as both client and server in a p2p communication but not at the same time.
4. False.
Audio and video applications should definitely have error free data. Error data will manipulate the audio or video that is to be seen actually and the application fails if it is giving wrong message to the receiver. But this will affect the real time applications of the audio and video. So these applications don't check for the errors in data. They are more concerned about time.
5. True
Audio and video applications are real time applications. The time delays in the data will affect the user experience. So, these applications will never tolerate time delays in data reception.
