what is open source software? Open Source software is distributed with

its source code. The Open Source Definition has three essential features:› It allows free re-distribution of the software

without royalties or licensing fees to the author

› It requires that source code be distributed with the software or otherwise made available for no more than the cost of distribution

› It allows anyone to modify the software or derive other software from it, and to redistribute the modified software under the same terms.
