Within the application, if you send the control from one flow to another flow we use VM.VM can be used as both inbound and outbound.

Outside the application, for example, A application want to send something to B application(external application) there we use JMS.

As per Mule documentation, VM transport is for intra-JVM communication between Mule flows. So, that means when you use a VM in your flow, you can communicate between different flows in the application.
A flow containing VM inbound cannot be called externally from external application as thus the flow is equivalent to a private flow used within the application. By default uses in-memory queues.
Please go through the documentation :- https://docs.mulesoft.com/mule-user-guide/v/3.8/vm-transport-reference

On the other hand as per Mule documentation, JMS is an external host, allows communication between different components of a distributed application and JMS transport lets you easily send and receive messages to queues and topics for any message service which implements the JMS specification.
A flow, which has JMS inbound can be called from externally unlike VM. Documentation is here :- https://docs.mulesoft.com/mule-user-guide/v/3.8/jms-transport-reference
