SMTP
SMTP (Simple Mail Transfer Protocol) is the stan-
dard Internet e-mail protocol. SMTP is a TCP/IP
protocol defining message format and includes a
message transfer agent that stores and forwards
mail.
SNMP
SNMP (Simple Network Management Protocol) is
a widely used network monitoring and control
protocol. SNMP hardware or software components
transmit network device activity data to the work-
station used to oversee the network.
SSID
SSID (Service Set Identifier) is the name desig-
nated for a LAN. It serves as a simple security
measure used in Wireless LANs (WLANs). The
SSID is attached to packets sent over WLANs.
This identifier acts as a password when a wire-
less device attempts communication on the
WLAN. Because an SSID distinguishes WLANS
from each other, routers and wireless devices
trying to connect to a WLAN must use the same
SSID.
Subnet Mask
Subnet Masks (SUBNETwork masks) are used
by IP protocol to direct messages into a specified
network segment (i.e., subnet). A subnet mask is
stored in the client machine, server or router and
is compared with an incoming IP address to
determine whether to accept or reject the packet.
SysLog Server
A SysLog server monitors incoming System log
messages and decodes the messages for logging
purposes.
TCP
(Transmission Control Protocol) is the transport
protocol in TCP/IP that ensures messages over
the network are transmitted accurately and
completely.
TCP/IP
TCP/IP (Transmission Control Protocol/Internet
Protocol) is the main Internet communications
protocol suite. TCP ensures that data is com-
pletely sent and received at the other end. The IP
component of TCP/IP provides data routability,
meaning that data packets contain the destination
station and network addresses, enabling TPC/IP
messages to be sent to multiple networks within
the LAN or in the WAN.
Telnet
Telnet is a terminal emulation protocol commonly
used on the Internet and TCP- or IP-based net-
works. Telnet is used for connecting to remote
devices and running programs. Telnet is a high
level application protocol that uses the TCP/IP
communications protocol.
UDP
(User Datagram Protocol) is a protocol within
TCP/IP that is used to transport information when
accurate delivery isn't necessary (for example,
realtime video and audio where packets can be
dumped since there is no time for retransmitting
the data).
Virtual Servers
Virtual servers are client servers (such as web
servers) that share resources with other virtual
servers (i.e., it is not a dedicated server).
VoIP
(Voice Over Internet Protocol) is a method used
to deliver voice information over the Internet.
VoIP services allow telephone calls using your
PC or LAN.
WEP
WEP (Wired Equivalent Privacy) is the most com-
mon security protocol for wireless LANs, provid-
ing the "equivalent" security available in hard-
wired networks.
