  • cooperative multitasking — (parallel, operating system)   A form of multitasking where it is the responsibility of the currently running task to give up the processor to allow other tasks to run. This contrasts with pre-emptive multitasking where the task scheduler periodically suspends the running task and restarts another. Cooperative multitasking requires the programmer to place calls at suitable points in his code to allow his task to be descheduled which is not always easy if there is no obvious top-level main loop or some routines run for a long time. If a task does not allow itself to be descheduled all other tasks on the system will appear to "freeze" and will not respond to user action. The advantage of cooperative multitasking is that the programmer knows where the program will be descheduled and can make sure that this will not cause unwanted interaction with other processes. Under pre-emptive multitasking, the scheduler must ensure that sufficient state for each process is saved and restored that they will not interfere. Thus cooperative multitasking can have lower overheads than pre-emptive multitasking because of the greater control it offers over when a task may be descheduled. Cooperative multitasking is used in RISC OS, Microsoft Windows and Macintosh System 7.

  • free software foundation — (body)   (FSF) An organisation devoted to the creation and dissemination of free software, i.e. software that is free from licensing fees or restrictions on use. The Foundation's main work is supporting the GNU project, started by Richard Stallman (RMS), partly to proselytise for his position that information is community property and all software source should be shared. The GNU project has developed the GNU Emacs editor and a C compiler, gcc, replacements for many Unix utilities and many other tools. A complete Unix-like operating system (HURD) is in the works (April 1994). Software is distributed under the terms of the GNU General Public License, which also provides a good summary of the Foundation's goals and principles. The Free Software Foundation raises most of its funds from distributing its software, although it is a charity rather than a company. Although the software is freely available (e.g. by FTP - see below) users are encouraged to support the work of the FSF by paying for their distribution service or by making donations. One of the slogans of the FSF is "Help stamp out software hoarding!" This remains controversial because authors want to own, assign and sell the results of their labour. However, many hackers who disagree with RMS have nevertheless cooperated to produce large amounts of high-quality software for free redistribution under the Free Software Foundation's imprimatur.
