Differences between call and JMP calls

1. The difference between JMP is that one is intra-segment call and the other is inter-segment call.

2. The call is very different, because the call will have an impact on the stack:
(1) The call's near call will not change the stack used, but the stack content has changed: the next command is pushed into the stack; if there is a parameter, the parameter is pushed into the stack.
(2) The Remote Call of call changes the stack used. Because the stack used changes, there is a copy process for the parameters.
