IS NSF A CONNECTION ORIENTED OR A CONNECTIONLESS PROTOCOL? EXPLAIN ANSWER

Hello Rodferna,

In general, the Network File System (NFS) is implemented using a
connectionless protocol such as the User Datagram Protocol (UDP) to
make it stateless.
  http://wombat.doc.ic.ac.uk/foldoc/foldoc.cgi?NFS
There are a number of links on this page that describe each of the
terms used.

There are implementations where NFS is implemented on top of a
connection oriented protocol such as the Transmission Control Protocol
(TCP), but the operation of the server and client are basically the
same in such a case.

The NFS server and mount protocols are described in detail in RFC-1094
  http://www.faqs.org/rfcs/rfc1094.html
Check section 1.3 which describes the use of "Stateless Servers" and
the rationale for it in top level terms. Appendix A.1 mentions briefly
the use of both UDP and TCP in the "mount service" (or protocol) which
is described separately from the NFS server protocol.

So - NFS itself is a connectionless protocol between the client and
server. It can be implemented on top of a connection oriented protocol
(such as TCP), but that does not change the basic nature of the NFS
protocol.

A good search string for this type of material includes:
  nfs file system
  nfs file system connectionless protocol
There are a number of additional resources available - though many of
the initial hits repeat the content of the first reference.
