Acronym for Free or Open Source Software. FOSS programs are those that have licenses that allow users to freely run the program for any purpose, modify the program as they want, and also to freely distribute copies of either the original version or their own modified version.
One major reason for the growth and use of FOSS technology (including LAMP) is because users have access to the source so it is much easier to fix faults and improve the applications. In combination with the open license, this simplifies the development process for many enterprises and gives them flexibility that simply isn’t available within the confines of a proprietary or commercial product.
Short for Field-Programmable Gate Array, a type of logic chip that can be programmed. An FPGA is similar to a PLD, but whereas PLDs are generally limited to hundreds of gates, FPGAs support thousands of gates. They are especially popular for prototyping integrated circuit designs. Once the design is set, hardwired chips are produced for […]
- FPM RAM
Short for Fast Page Mode RAM, a type of Dynamic RAM (DRAM) that allows faster access to data in the same row or page. Page-mode memory works by eliminating the need for a row address if data is located in the row previously accessed. It is sometimes called page mode memory. FPM RAM is being […]
Short for floating-point unit, a specially designed chip that performs floating-point calculations. Computers equipped with an FPU perform certain types of applications much faster than computers that lack one. In particular, graphics applications are faster with an FPU. Some microprocessors, such as the Intel 80486 and Pentium, have a built-in FPU. With other microprocessors, you […]
A fully qualified domain name consists of a host and domain name, including top-level domain. For example, www.definithing.com is a fully qualified domain name. www is the host, definithing is the second-level domain, and.com is the top level domain. A FQDN always starts with a host name and continues all the way up to the […]
Short for Frame Relay Assembler/Disassembler, a communications device that breaks a data stream into frames for transmission over a Frame Relay network and recreates a data stream from incoming frames. A Frame Relay router serves the same purpose but provides more intelligence in avoiding congestion.
