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.
