[Arundhati Roy]

Hi,

Can anybody explain to me this question:

Which of the following statements describes the advantages of RMI over Socket Programmimg?

A. RMI offers better speed than socket programming.

B. RMI is simpler to implement over socket programming.

C. You can pass tramsmit objects across RMI, but not across sockets.

D. RMI offers interactive communication, but sockets do not.

E. Unlike in sockets,no protocol design is required in RMI.


Answer B and E

And also tell me the difference b/w RMI and Socket programming.


Thanks In Advance

This might be more technical than what's needed for the SCJA exam, but here's a good reference to skim for details (and you might want to skip to the end summary first): Programming Sockets and RMI: A Java Tutorial.

Thanks for the study material...

RMI is simpler to implement over socket programming.]RMI is simpler to implement over socket programming.

Because, RMI uses socket behind the scene.

Unlike in sockets,no protocol design is required in RMI.

RMI is higher level than socket. Additionaly RMI is slower because of that.

what is the reason why socket is not interactive?
I think it can have no reply, ok?

I think so, you have to create your own protocol to make socket interactive.
