1.How does the synchronous and asynchronous communication work? also with reference to the above mentioned what are the signals used for asynchronous communication.
16 I have been learning the internals of an operating system and I am confused as to what the basic difference between synchronous and asynchronous I/O is. How does an operating system know whether it is synchronous or asynchronous?
1 Synchronous functions are blocking while asynchronous functions are not. In synchronous functions, statements complete before the next statement is run. In this case, the program is evaluated exactly in order of the statements and execution of the program is paused if one of the statements take a very long time.
What is the difference between asynchronous and non-blocking calls? Also between blocking and synchronous calls (with examples please)?
Synchronous / Asynchronous communication has nothing to do with application waiting or not for resources. Synchronous communication is when communication looks like ping-pong one request and one response in that particular order. Asynchronous communication is when there could be multiple requests and responses could return in random order.
The invocation may be immediate as in a synchronous callback, or it might happen at a later time as in an asynchronous callback. We must also define "synchronous" and "asynchronous".
