In 1998, the IEEE with document 802.1w introduced an evolution of STP: the R apid S panning T ree
P rotocol, 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".
