Parameters	Stateful	Stateless
1. State	A Stateful server remember client data (state) from one request to the next.	A Stateless server keeps nostate information
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.
6.Extra services	Stateful servers can also offer clients extra services such as file locking, and remember read and write positions	It does not have to implement the state accounting associated with opening, closing, and locking of files.
7.Operations	Open, Read, Write, Seek, Close	Read, Write
8.Example,(Tip: you can draw them outside this two column format)
