Forward compatible, also known as upward compatible, refers to software that runs not only on the computer for which it was designed, but also on newer and more powerful models. Forward compatibility is important because it means you can move to a newer, larger, and more sophisticated computer without converting your data. An example of upward/forward compatibility is the specification that a web browser ignore HTML tags not recognised. Ignoring data or application instructions not recognized is the typical behavior of forward compatible systems.

The Fourier Transform, named after Joseph Fourier, is an integral transform that re-expresses a function in terms of sinusoidal basis functions, i.e. as a sum or integral of sinusoidal functions multiplied by some coefficients ("amplitudes"). Fourier Transform technique is used to evaluate the importance of various frequency cycles in a time series pattern.

A fourth-generation programming language (4GL) is a programming language closer to human languages than typical high-level programming languages. Such languages arose after the introduction of modern, block-structured third-generation programming languages, which improved the process of software development. Most 4GLs are used to access databases. For example, a typical 4GL command is FIND ALL RECORDS WHERE COMPANY IS "JAVVIN".

Function point analysis (FPA) is a method used to gauge the size and complexity of computer software, employing a function point as a unit of measure. Function points are a unit measure for software size, much like an hour is to measure time.

Free software, according to the definition of the Free Software Foundation (FSF), refers to the software that everyone is free to copy, redistribute and modify. That implies that it must be available as source code. It does not imply that it is free of charge, so anyone can sell free software so long as they don't impose any new restrictions on its redistribution or use.

Free software license refers to a license which grants permissions to the recipient to remove any ownership issues which would otherwise prevent the software from being free software. With free software license, recipients of the software is granted the freedom to modify and redistribute the software by the copyright holder.

FreeBASIC is an open source (under GPL) 32-bit, BASIC programming language compiler. It is designed to be syntax compatible with QuickBASIC, while expanding on the language and capabilities. It compiles for DOS, Microsoft Windows and Linux, and is being ported to other platforms.

FreeBSD is a Unix-like free operating system descended from AT&T UNIX via the Berkeley Software Distribution (BSD) branch through the 386BSD and 4.4BSD operating systems. It runs on processors compatible with the Intel x86 family, as well as on many other processors such as AMD64 and PowerPC processors. It also runs on the PC-98 architecture. Support for the ARM and MIPS architectures is currently in development.

FreeDoom is a Doom WAD file intended to be used instead of the copyrighted file from the original Doom and Doom II. The idea is that since the source to Doom is released as open source you can combine the free game engine with the free WAD to create an entirely free game. This also makes it possible to use all user-made WADs that require the original (and copyrighted) WAD by replacing it.

FreeSBIE is a LiveCD (LiveDistro) type of operating system that is able to load directly from a bootable CD without any installation process and without any hard disk. It is based on the FreeBSD operating system.

Explanation : Single In-line Memory Module (SIMM) is a circuit board that can hold a group of memory chips (Typically, eight (on Macintoshes) or nine (on PCs) RAM chips). On PCs, the ninth chip is often used for parity error checking. SIMMs are measured in bytes. Memory modules evolved from the need of saving motherboard space and effortless memory expansion. Instead of plugging 8 or 9 single DRAM chips, you could now simply add one memory module to increase the memory of the computer instantly.
