In the nRF8001, how is Pipe different from Handle of attributes?

Question

The nRF8001 provides pipes to the Characteristics on the local GATT Server and the remote GATT server. How is this different from the handles of Attributes.

A pipe is very similar to a handle, but there are some differences that should be noted, for example that a pipe belongs to an operation on an attribute, not the attribute itself. This means that if one characteristic have for example both the read and the write properties, it will be exposed over two different pipes. 
 There is a chapter 20 in the nRF8001 PS that tries to explain the concept, so it might be worth having a look at it.
