Interview Questions that can be asked on TCP/IP, UDP, Socket Programming ?

Question

I am going for an interview day after tomorrow where i will be asked vaious questions related to TCP/IP and UDP. As of now i have prepared theoritical knowledge about it. But now I am looking up for gaining some practicle knowledge related to how it works in a network. What all is going in vaious .NET classes.

I want to create a very small application like a chat or something that can make me all these concepts very much clear. Could you please suggest some questions related to TCP/IP that you generally ask or that you might have faced.

How communication is going from server to client. Right now I am studying TcpClient, TcpListener and UdpClient Class but I want to implement all of them so as to get aware about its working.

Is Chat application a Tcp/IP application ?

I would appreciate your help.

Answer 1

Where to start from?

• What is the essential difference between TCP and UDP?
• Which one uses a "handshake"? How many steps?
• Which one is considered "unreliable"?
• For which OS will TCP fit? Linux or Windows?

And for a bit more advanced questions:

• What is a TCP window stack? How does it affect it?
• What is a non-blocking operation?

..... very possible to learn, good luck!
