Parameters Stateful Stateless

2. Programming Statefulserver is harder to code Statelessserver is straightforward to code
3.Efficiency MoreBecause clients do not have to provide full file information every time they perform an operation Less because information needs to be provided
4.Crash recovery Difficult due to loss of information Can easily recover from failure. Because there is no state that must be restored
5.Information transfer Using a Stateful,file server, the client can send less data with each request Using a stateless file server, the client must,specify complete file names in each request specify location for reading or writing re-authenticate for each request.

7.Operations Open, Read, Write, Seek, Close Read, Write
