Description
S
SMTP (Simple Mail
Transfer Protocol)
SMTP is an Internet standard for electronic mail (e-mail)
transmission
SSH (Secure Shell
Protocol)
SSH is a network protocol that allows data to be exchanged
using a secure channel between two networked devices.
SSID
A Service Set Identification is a thirty-two character (maximum)
alphanumeric key identifying a wireless local area network. For
the wireless devices in a network to communicate with each
other, all devices must be configured with the same SSID. This is
typically the configuration parameter for a wireless PC card. It
corresponds to the ESSID in the wireless Access Point and to
the wireless network name.
SNMP (Simple Network
Management Protocol)
SNMP provides a management frame to monitor and maintain
the network devices. With SNMP function enabled, network
administrators can easily monitor the network performance,
detect the malfunctions and configure the network devices.
T
TCP (Transfer Control
Protocol)
Connection-oriented transport layer protocol that provides
reliable full-duplex data transmission.
TCP/IP (Transmission
Control Protocol/ Internet
Protocol)
Common name for the suite of protocols to support the
construction of worldwide Internet works. TCP and IP are the two
best-known protocols in the suite.
TDMA (Time Division
Multiple Access)
TDMA (Time Division Multiple Access) cuts each wireless data
frame into certain number of time slots according to the client
connections priority, greatly boosting efficiency of the wireless
channel.
U
UDP (User Datagram
Protocol)
UDP is a simple protocol that exchanges datagram without
acknowledgments or guaranteed delivery, requiring that error
processing and retransmission be handled by other protocols.
UPnP (Universal Plug and
Play)
UPnP is a set of networking protocols for primarily residential
networks
without enterprise class devices that permits
networked devices.
V
VLAN (Virtual Local Area
Network)
Group of devices on one or more LANs that are configured (using
management software) so that they can communicate as if they
were attached to the same wire, when in fact they are located on
a number of different LAN segments. Because VLANs are based
on logical instead of physical connections, they are extremely
flexible.
VPN (Virtual Private
Network)
Enables IP traffic to travel securely over a public TCP/IP network
by encrypting all traffic from one network to another.
