Remote Method Invocation
1. What is Remote Method Invocation (RMI) and what is the purpose of RMI?

    This is a RPC call in a java way. When using this it handles all of the bolder plating( network set up and tear down, data passing etc )


2. Discuss the relationship between Remote Procedure Call and Remote Method Invocation

    In java we use methods we translate RPC into Remote Method Invocation.

3. Discuss Remote Procedure Call/Method Invocation in relation to space, time, and flow decoupling


Space
    You need to know the addresse of the part you wanna call. It's p2p ( point 2 point )
Time
    When it calls the methods it is blocking waiting for the response aka synkronus
Flow
    On the client there is no decoupling because we send the message and we expect a response right away. ( Fails )
    On the server is flow devopuled because it does not get block it self on a request. ( It just answers when it gets a request ) ( Passes )


4. Discuss the role of Remote Procedure Call/Method Invocation in distributed systems



5. What is a Java Virtual Machine (JVM)?



6. What is a remote object?



7. Discuss the three main layers in the RMI architecture, i.e.
    _ Stub and skeleton layer
    _ Remote Reference layer
    _ Transport layer
8. What is a remote interface?



9. What is serialization?


10. What is a RMI Registry?
