What is the difference between sophisticated and complicated

Question

All, I see these words are used many times literally or verbally. But I really don't know what is the difference between them.

Please review one of them which I got from a read.

After an obligatory Hello World–caliber application, we construct a more sophisticated application that implements a daytime server.

Answer 1

Sophisticated implies a level of elegance and intelligent design that might not be present in something that is just complicated. Also, a simple application could potentially be sophisticated if it had a lot of capacity despite its simplicity.
