RJ-45 C
ONNECTOR
A connector for twisted-pair wiring.
S
PLITTER
A filter to separate DSL signals from POTS signals to prevent mutual
interference.
SNTP
Simple Network Time Protocol: SNTP allows a device to set its internal
clock based on periodic updates from a Network Time Protocol (NTP)
server. Updates can be requested from a specific NTP server, or can be
received via broadcasts sent by NTP servers.
TCP/IP
Transmission Control Protocol/Internet Protocol. Protocol suite that
includes TCP as the primary transport protocol, and IP as the network layer
protocol.
TIA
Telecommunications Industry Association
UDP
User Datagram Protocol. UDP provides a datagram mode for packet-
switched communications. It uses IP as the underlying transport
mechanism to provide access to IP-like services. UDP packets are delivered
just like IP packets – connection-less datagrams that may be discarded
before reaching their targets. UDP is useful when TCP would be too
complex, too slow, or just unnecessary.
UP
N
P
Universal Plug-and-Play. A set of protocols that allows devices to connect
seamlessly and simplifies the deployment of home and office networks,
using auto-discovery of other network devices, acquiring information about
device capabilities, and requests for services.
UTP
Unshielded twisted-pair cable.
VPN
Virtual Private Network. A secure tunnel used to protect data passing from
one network to another over the Internet.
WAN
Wide Area Network. A computer network that spans a relatively large
geographical area. Typically, a WAN consists of two or more local-area
networks (LANs).
