- remote procedure call — (networking, programming) (RPC) A protocol which allows a program running on one host to cause code to be executed on another host without the programmer needing to explicitly code for this. RPC is an easy and popular paradigm for implementing the client-server model of distributed computing. An RPC is initiated by the caller (client) sending request message to a remote system (the server) to execute a certain procedure using arguments supplied. A result message is returned to the caller. There are many variations and subtleties in various implementations, resulting in a variety of different (incompatible) RPC protocols.

- tool command language — (language) /tik*l/ (Tcl) An interpreted string processing language for issuing commands to interactive programs, developed by John Ousterhout at UCB. Each application program can extend tcl with its own set of commands. Tcl is like a text-oriented Lisp, but lets you write algebraic expressions for simplicity and to avoid scaring people away. Though originally designed to be a "scripting language" rather than for serious programming, Tcl has been used successfully for programs with hundreds of thousands of lines. It has a peculiar but simple syntax. It may be used as an embedded interpreter in application programs. It has exceptions and packages (called libraries), name-spaces for procedures and variables, and provide/require. It supports dynamic loading of object code. It is eight-bit clean. It has only three variable types: strings, lists and associative arrays but no structures. Tcl and its associated GUI toolkit, Tk run on all flavors of Unix, Microsoft Windows, Macintosh and VMS. Tcl runs on the Amiga and many other platforms. See also expect (control interactive programs and pattern match on their output), Cygnus Tcl Tools, [incr Tcl] (adds classes and inheritence to Tcl), Scriptics (John Ousterhout's company that is the home of Tcl development and the TclPro tool suite), Tcl Consortium (a non-profit agency dedicated to promoting Tcl), tclhttpd (an embeddable Tcl-based web server), tclx (adds many commands to Tcl), tcl-debug.

- universal disk format — (storage, standard) (UDF) A CD-ROM file system standard that is required for DVD ROMs. UDF is the OSTA's replacement for the ISO 9660 file system used on CD-ROMs, but will be mostly used on DVD. DVD multimedia disks use UDF to contain MPEG audio and video streams. To read DVDs you need a DVD drive, the kernel driver for the drive, MPEG video support, and a UDF driver. DVDs containing both UDF filesystems and ISO 9660 filesystems can be read without UDF support. UDF can also be used by CD-R and CD-RW recorders in packet writing mode.
