features added, including support for symbolic links, hard links, and larger file sizes.

SSID – Service Set Identifier

A unique network name, or identifier, that differentiates one wireless LAN from another. All access points and clients attempting to connect to a specific WLAN must use the same SSID.

Subnet

A portion of a network. The subnet is distinguished from the larger network by a subnet mask that selects some of the computers of the network and excludes all others. The subnet’s devices remain physically connected to the rest of the network, but they are treated as though they were on a separate network.

Subnet mask

A mask that defines a subnet. See also Network mask.

Switching

Routing data traffic by setting up temporary connections between two or more network points. This will take the data toward its intended destination.

TCP – Transmission Control Protocol

See TCP/IP.

TCP/IP – Transmission Control Protocol / Internet Protocol

The basic protocols used on the Internet. TCP is responsible for dividing data up into packets for delivery and reassembling them at the destination. IP is responsible for delivering the packets from source to destination. When TCP and IP are bundled with higher-level applications such as HTTP, FTP, Telnet, and so on, TCP/IP refers to this whole suite of protocols.

TFTP – Trivial File Transfer Protocol A TCP/IP protocol commonly used for software downloads.

TKIP – Temporal Key Integrity Protocol A protocol used for WPA data encryption. It ensures that a unique master key is generated for each packet, supports message integrity and sequencing rules, and supports re-keying mechanisms. TKIP avoids the problems of WEP static keys by dynamically changing data encryption keys.

UDP – User Datagram Protocol

Aconnection-less transport service that dispenses with the reliability services provided by TCP. UDP gives applications a direct interface with IP and the ability to address a particular application process running on a host via a port number, without setting up a connection session.

UPnP – Universal Plug and Play

A networking architecture that provides compatibility among networking equipment, software, or between equipment and software.

UPnP IGD – UPnP Internet Gateway Device A standard used by UPnP aware clients, such as MSN Messenger, to work properly from behind a NAT.

UMTS – Universal Mobile

Telecommunications Service

A 3G wireless system that delivers high- bandwidth data and voice services to mobile users. UMTS has an air interface based on WCDMA and a core network based on the General Packet Radio Service (GPRS).

URL – Uniform Resource Locator

The address of a resource on the Internet, for example www.ericsson.com.

USB – Universal Serial Bus

An interface for connecting peripherals such as storage devices and printers to a host.
