This is a stream-based protocol
designed to allow query, retrieval, posting, and distribution
of mail messages. Normally this protocol is
used in conjunction with other mail retrieval protocols
such as point of presence (POP). However, not
all uses of SMTP involve email data transfer. Some
Simple Object Access Protocol (SOAP) applications
have also relied on SMTP to transfer application data.
Simple Network Management Protocol (SNMP)
A network protocol (originally designed for the
Internet) used to manage devices from different vendors.
The protocol originally appeared in the 1980s
and relies on Protocol Data Unit (PDU) messages to
transmit requests. SNMP-compliant devices, known
as agents, respond to these requests by sending
information from Management Information Bases
(MIBs) to the requestor.
Smart Card
A type of user identification used in place of passwords.
The smart card contains an encrypted chip
that provides the user identification information;
most smart cards are about the size and shape of a
credit card. The use of a smart card makes it much
harder for a third party to break into a computer
system using stolen identification.
