Synchronous vs Asynchronous Processing

Report a typo

Consider a server application that handles multiple client requests. In the context of multithreading and multiprocessing in operating systems, what would be the differences between handling these requests synchronously and asynchronously?

Select one or more options from the list

In synchronous processing, the server handles one request at a time, blocking all others until it is fully processed, while in asynchronous processing, multiple requests can be processed at the same time without blocking.

In synchronous processing, signals are used to indicate that a request is ready to be processed, but in asynchronous processing, signals are not used and processing begins immediately.

In synchronous processing, the server can handle multiple requests in parallel, reducing wait time. Whereas in asynchronous processing, requests are put into a queue and processed one after another, which might lead to longer wait times.

In asynchronous processing, the server places incoming requests into a buffer, and signals are used to start processing them. In synchronous processing, requests are processed immediately as they come in and no signals are required.
