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

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
