Lookup Transformation.Give me one or two examples please?

1) The connected lookup t/r connected other transformations in the pipe line and it recives input data directly from pipe line.
where as unconnected lookpup t/r not connected other t/r in the pipe line and it recive input data from the result of :LKP Expression in an other t/r,that support expressions.
2)Connected lookup support user defined functions
Unconnectd doesn't support user defined functions.
3) It returns multiple output values to other t/r
Unconnected returns single output value to other t/r.
4)Connected lookup support static and dynamic cache
Unconnected supports only static cache.
5)Connected lookup cache includes output ports in the lookup condition
Where as in unconnected lookup cache include lookup ports of lookup condition.
6)Connected lookup gives multiple output ports to other t/r.
Unconnected lookup gives single output port to other t/r.
