Answer 1

That is a very wide question...I am going to just give a brief high-level answer and suggest that you do some more searching as there are is already a lot written on each subject. But, hopefully this should give you a push in the right direction.

First, typically when people refer to WCF Services and Web Services, they are referring to the newer WCF conventions that make service calls fairly generic (they can be SOAP, REST, etc) and the old .asmx SOAP method of Web Services. So, along these lines, I would suggest looking more into WCF and SOAP/.ASMX for the difference of WCF and older Web Services.

As to WCF and REST, they are not the same. REST is more of an architecture, whereas WCF is a framework. As I already mentioned, WCF can be used to make SOAP calls or REST calls. I am not sure I can add much more without going into greater detail.

I will see if I can find some good articles on REST and WCF a little later, though. Personally, I do not see a reason to even pursue very far into the older way of calling web services (.ASMX pages) as WCF has pretty much made that obsolete. However, learning many different ways to skin a cat can be useful in an endeavor to find what fits you best.

Again, this is VERY high level, but these are very general topics with a lot surrounding each, so hopefully a high level overview will help direct you in studying deeper on each subject.
