Hi Rajesh,
Type 3 ABAP Connection :
ex 1) If we want to execute any function module from one SAP system in another , we need type 3.
We define an RFC destination say ECC6CLNT100 with required parameters.
and to test it go to SE37, select any common sap function module and when you execute that it will ask for RFC destination. you provide this destination and the function module will be executed  in the target system.
ex2) when you create a partner profile, you need to create a port and for creating a port, we need to specify an RFC destination. here also we use type 3.
Type H.
ex1) when we need to send xml messages from an SAP system to any other system, we need this.
For example when we send messages using proxy from SAP system to the integration engine of XI, we need type H.
Type T.
ex1) To we make an RFC call from R/3 to XI , we use sender RFC adapter in XI.
In R/3 system we need to create an RFC destination of type T.
Rajesh, I hope it answers all your queries.
