Explain the difference between TCP and UDP

4 Answers

That's really as difficult as it gets?

UDP packet processing is faster compared to TCP packet processing. This is because once TCP packets are delivered to the destination, an acknowledgement is expected at the transmission end. If no acknowledgement is received, re-transmission of packets occurs at the transmission end. This is opposite to UDP operation, in which no acknowledgement is necessary. Less

TCP is a reliable protocol that utilizes windowing and acknowledgement packets to ensure all traffic is transmitted and received UDP is an unreliable protocol that does not utilize windowing and acknowledgements, and is good to use when you can't re-transmit a packet (EG a voice or video packet) Less

Though they asked many technical questions on Networking. However, it is always the attitude which matters as a fresher. The most obvious question they would shoot at you is why do they have to hire you.

1 Answers

Well, there is no Right or Wrong answer to this question. You have to make the interviewer feel that how important this job is for you, even though you are a fresher you have less technical experience. Attitude is the main key to crack it. If you can show them you are a fast learner and ready to learn new technologies. It would be more likely that you would make it. Less
