>>1) Difference between Synchronous & ASynchronous communication?
A simple search would have got you the answer.... Sync is two way communication i.e. you send a request and get a response back... Async is one way communication i.e. no response is sent from the receiver...
>>2) How should we decide whether it is a Sync or Async scenario?
Depends upon the system and the business use case... you cannot receive a response from file system.. so Sync can't designed on File system.. DB can have both Sync and Async but again the business logic only decides to choose the scenario type. there is no thumb rule for this..
