Final answer:
The continuation of the main function's execution after a function is invoked depends on whether the programming model is synchronous or asynchronous. In asynchronous execution, the main function can perform other tasks without waiting for the called function to complete.
Step-by-step explanation:
When a function is invoked in a programming context, whether or not the main function continues executing depends on the execution model of the program. In a synchronous execution model, the main function will wait for the called function to complete before resuming its own execution. In contrast, with asynchronous execution, the main function can continue to execute other tasks while the called function is being processed, effectively allowing for multitasking and not wasting time waiting for the function to return.
However, what you're referring to may also be a concept of concurrency or parallelism, which allows multiple functions or processes to run simultaneously. This is often used in programming to optimize the use of CPU and improve the efficiency of the application.
