Protocol:
A standard way of exchanging information between computers.
RADIUS (Remote Authentication Dial In User Service):
A server that issues authentication key to
clients.
RAM (Random Access Memory):
Non-permanent memory.
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.
Router
: Device that can connect individual LANs and remote sites to a server.
Roaming
: The ability to use a wireless device while moving from one access point to another without
losing the connection.
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.
Static IP Address:
A permanent IP address is assigned to a node in a TCP/IP network. Also known as
global IP.
STP (Shielded Twisted Pair):
Twisted Pair cable wrapped in a metal sheath to provide extra protection
from external interfering signals.
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.
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.
TCP/IP:
TCP/IP (Transmission Control Protocol/Internet Protocol) is 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).
