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.
