RPC is an IPC mechanism that specifies that the processes interact via procedure call interface.

Once the result is computed, it will take the reverse path. It will go through the server step that will first create a buffer for that result,
then it will send the response back via appropriate client connection, arriving on the client side into the RPC run time.
the packets will be received. the result will be extracted from those packets by the client side stub, be placed somewhere in memory in the client address space, and ultimately the procedure will return to the client process.
Before that, the client process will be blocked, and the application will be suspended here.

The encoding specifies the data layout when it's serialized to the bytee stream, so that anybody that looks at it can actually make sense of it.

To complete the quiz, download the square.x file (if following along with the hints, you will need to rename it to square.x), and run rpcgen!
You can run rpcgen on the Ubuntu VM provided with this class. If you have not setup the Ubuntu VM yet, follow the Ubnutu VM Setup Instructions.
Quiz Errata
There are two issues with the rpcgen commands. First, you should use the following format:
- rpcgen square.x [flags]
And, because the flags may be difficult to read, here are the full commands:
- rpcgen square.x -C
- rpcgen square.x -C -M
