Hello Friend! I want to explain your required questions::

As I hope you know well about Internet.

So, Intranet is a a type of networking with which you are connected to your server. You can also say that you are connectd through LAN(Locan Area Network).

Let me give u an example that if we take the example of any professional institution that there is a main server & it is connected & providing information to all its labs & other computers & you are connected in thelab to internet through intranet.
&
Extranet is that thing that you have two nodes on two different locations & you are connected to both the nodes in such a way that no one can access that.
For Example: Your one node is in Lahore & other is in Islamabad & you are connected to the both through WAN(Wide Area Network) then this is known as Extranet.
