In 1998, the IEEE with document 802.1w introduced an evolution of STP: the Rapid Spanning Tree
Protocol, which provides for faster spanning tree convergence after a topology change. Standard IEEE
802.1D-2004 now incorporates RSTP and obsoletes STP, while at the same time being
backwards-compatible with STP.

SAMBA
Samba is a program running under UNIX-like operating systems that provides seamless integration
between UNIX and Microsoft Windows machines. Samba acts as file and print servers for Microsoft
Windows, IBM OS/2, and other SMB client machines. Samba uses the Server Message Block (SMB)
protocol and Common Internet File System (CIFS), which is the underlying protocol used in Microsoft
Windows networking.
Samba can be installed on a variety of operating system platforms, including Linux, most
common Unix platforms, OpenVMS, and IBM OS/2.
Samba can also register itself with the master browser on the network so that it would appear in
the listing of hosts in Microsoft Windows "Neighborhood Network".
SHA
SHA is an acronym for Secure Hash Algorithm. It designed by the National Security Agency (NSA) and
published by the NIST as a U.S. Federal Information Processing Standard. Hash algorithms compute a
fixed-length digital representation (known as a message digest) of an input data sequence (the message)
of any length.
Shaper
A shaper can limit the bandwidth of transmitted frames. It is located after the ingress queues.
SMTP
SMTP is an acronym for Simple Mail Transfer Protocol. It is a text-based protocol that uses the
Transmission Control Protocol (TCP) and provides a mail service modeled on the FTP file transfer service.
SMTP transfers mail messages between systems and notifications regarding incoming mail.
