- portable network graphics — (file format) /ping/ (PNG) An extensible file format for the lossless, portable, well-compressed storage of raster images. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-colour, greyscale and truecolour images are supported, plus an optional alpha channel. Sample depths range from 1 to 16 bits. PNG is designed for on-line viewing applications, such as the World Wide Web, so it is fully streamable with a progressive display option. PNG is robust, providing both full file integrity checking and simple detection of common transmission errors. Also, PNG can store gamma correction and chromaticity data for improved colour matching on heterogeneous platforms.

- spectral band replication — (audio, compression) (SBR) Guessing the nontransmitted higher frequency range of a compressed audio file by some helper bits (transmiited with the stream) and the transmitted base band. SBR allows a restoration (not reconstruction) of the upper frequency range without lots of bits. It was developed by Coding Technology, and is useful for medium and high quality coding at low and medium data rates. It is used by Digital Radio Mondiale and MP3 Pro.

- transport layer interface — (networking, programming) (TLI, or "Transport Level Interface") A protocol-independent interface for accessing network facilities, modelled after the ISO transport layer (level 4), that first appeared in Unix SVR3. TLI is defined by SVID as transport mechanism for networking interfaces, in preference to sockets, which are biased toward IP and friends. A disavantage is that a process cannot use read/write directly, but has to use backends using stdin and stdout to communicate with the network connection. TLI is implemented in SVR4 using the STREAMS interface. It adds no new system calls, just a library, libnsl_s.a. The major functions are t_open, t_bind, t_connect, t_listen, t_accept, t_snd, t_rcv, read, write. According to the Solaris t_open man page, XTI (X/OPEN Transport Interface) evolved from TLI, and supports the TLI API for compatibility, with some variations on semantics.

- unemployment compensation — an allowance of money paid, usually weekly, to an unemployed worker by a state or federal agency or by the worker's labor union or former employer during all or part of the period of unemployment.
- xpress transport protocol — (networking, protocol) (XTP) A transport layer protocol for high-speed networks promoted by the XTP Forum. XTP provides protocol options for error control, flow control, and rate control. Instead of separate protocols for each type of communication, XTP controls packet exchange patterns to produce different models, e.g. reliable datagrams, transactions, unreliable streams, and reliable multicast connections. Contrast with Transmission Control Protocol. XTP does not employ congestion avoidance algorithms.
- yakut autonomous republic — an autonomous republic in the NE Russian Federation in Asia. 1,198,146 sq. mi. (3,103,200 sq. km). Capital: Yakutsk.
