What is WCF readerQuotas and maxArrayLength?

Question

Can anyone explain WCF <readerQuotas> to me? Specifically maxArrayLength.

According to MSDN:

maxArrayLength

A positive integer that specifies the maximum allowed array length of data being received by Windows Communication Foundation (WCF) from a client. The default is 16384.

What is it? Bytes?

What happens if I don't set it?

What happens if I set it and the message returned goes beyond the specified length?

Isn't it possible that the message may exceed even the maximum value set? Then what's the point of setting this value?

questions are good, but in one question u have asked 5 to 6 questions — Freelancer, Apr 25 '13 at 06:33
@Freelancer Well they are all related so didn't really see the point asking them separately... :) — Aditi, Apr 25 '13 at 06:35

I am trying to simplify this as best as possible:

maxArrayLength = how many elements can your array or list hold.
maxBytesPerRead = max bytes for the entire message
maxDepth = how many levels down can an array go? For example a class can have an arrays, and each element has an array, and each element of that has an array.....
maxStringContentLength = max XML content length
