]]> The SNMP protocol is used by network management systems to communicate with network elements.For this to work, the network element must be equipped with an SNMP agent.

Most professional-grade network hardware comes with an SNMP agent built in. These agents must be enabled and configured to communicate with the network management system.Operating systems, such as Unix and Windows, can also be configured with SNMP agents.

Simple Network Management Protocol (SNMP) is a UDP-based network protocol. It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention.

]]> Network File System (NFS) is a network file system protocol originally developed by Sun Microsystems in 1984, allowing a user on a client computer  to access files over a network in a manner similar to how local storage is accessed. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call (ONC RPC) system. The Network File System is an open standard defined in RFCs, allowing anyone to implement the protocol.

The NFS protocol is designed to be independent of the computer, operating system, network architecture, and transport protocol. This means that systems using the NFS service may be manufactured by different vendors, use different operating systems, and be connected to networks with different architectures. These differences are transparent to the NFS application, and thus, the user.
