Explain Circular Dependencies.

Circular Dependencies:

To know the problem of circular dependencies consider a file server which uses a timeserver to acquire the current time when a file is accessed. Circular dependencies can arise if the timeserver also utilizes the file server. For illustration suppose that a programmer is asked to modify the time server therefore it remains a record of each request. If the programmers select to have the time server become a client of the file server, a cycle can outcome; the file server is client of the time server that becomes a client of the file server etc.
