SMTP Authentication
Specification that adds user authentication functions to SMTP, which is used
for sending E-mail.
When sending E-mail, authentication of the user is performed by the SMTP
server, and the E-mail message is permitted to be sent only if authentication
was successful.
SNMP
SNMP (Simple Network Management Protocol) is actually a set of protocols
for managing complex networks. SNMP works by sending messages to differ-
ent parts of a network. SNMP-compliant devices, called agents, store data
about themselves in Management Information Bases (MIBs) and return this
data to the SNMP requesters.
TCP/IP
Most networks combine TCP (Transmission Control Protocol) with the
lower-level protocol IP (Internet Protocol). TCP establishes a virtual connec-
tion between two host systems and guarantees the delivery of data between
them while IP specifies the format and addressing of this data sent between
these two host systems.
WSD print
Printing is possible using the WSD (Web Service on Devices) function
installed in Windows Vista. A connection supports WSD, detects the printer
on the network automatically and connects. Specifying a WSD printer when
printing from Windows Vista allows printing using Web service for communi-
cation.
