6. Briefly describe the difference between synchronization and asynchronism.
Synchronous mode is blocking mode and asynchronous mode is non-blocking mode.
Synchronization means that when a program executes a request, if the request takes some time to return information, the program will wait until it receives the returned information.
Asynchronous means that the program does not need to wait all the time, but continues to perform the following operations, regardless of the state of other programs. When a message returns, the system will inform the program to handle it, which can improve the efficiency of execution.
