PPPoE PPPoE (Point-to-Point Protocol Over Ethernet) is used for
running PPP protocol (normally used for dial-up Internet
connections) over an Ethernet.
Preamble Preamble refers to the length of a CRC (Cyclic Redundancy
Check) block that monitors communications between roam-
ing wireless enabled devices and access points.
Protocol A protocol is a rule that governs the communication of data.
RIP RIP (Routing Information Protocol) is a routing protocol that
is integrated in the TCP/IP protocol. RIP finds a route that is
based on the smallest number of hops between the source
of a packet and its destination.
RTS RTS (Request To Send) is a signal sent from the transmitting
station to the receiving station requesting permission to trans-
mit data.
Server Servers are typically powerful and fast machines that store
programs and data. The programs and data are shared by
client machines (workstations) on the network.
SMTP SMTP (Simple Mail Transfer Protocol) is the standard Inter-
net 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 hard-
ware or software components transmit network device
activity data to the workstation used to oversee the network.
SSID SSID (Service Set Identifier) is a security measure used in
WLANs. The SSID is a unique identifier attached to packets
sent over WLANs. This identifier emulates a password when
a wireless device attempts communication on the WLAN.
Because an SSID distinguishes WLANS from each other,
access points and wireless devices trying to connect to a
WLAN must use the same SSID.
Subnet Mask Subnet Masks (SUBNETwork masks) are used by IP proto-
col 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 ad-
dress to determine whether to accept or reject the packet.
SysLog Server A SysLog server monitors incoming Syslog 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 trans-
mitted accurately and completely.
TCP/IP (Transmission Control Protocol/Internet Protocol) is
TCP/IP
the main Internet communications protocol. The TCP part
ensures that data is completely sent and received at the
other end. Another part of the TCP/IP protocol set is UDP,
which is used to send data when accuracy and guaranteed
packet delivery are not as important (for example, in real-
time video and audio transmission).
