25 Reasons to Convert to Linux
Businesses, educational institutions, governmental agencies and other organizations around the world are converting1 their computer operating systems from Microsoft Windows to Linux at an increasing pace. They are likewise converting their application programs from commercial software to free software (also referred to as open source software). There are at least 25 reasons for this situation, including:
(1) Because it is licensed under a free software license2, Linux (as well as other free software) is available at no cost. It can be downloaded from the Internet for free, and it can be purchased in disk or box form at trivial cost. One copy can be used on as many computers as desired with no restrictions. This is in sharp contrast to Microsoft Windows, which can easily cost US$100 or more per computer.
(2) Because it is free software, Linux is also free in the sense that anybody is permitted to modify it, including its source code, in any way desired. If modified versions are not redistributed (i.e., given away or sold outside of an organization), they can be kept secret. This is also in sharp contrast to Microsoft Windows, for which modification of the software is generally not permitted. Source code is the original version of a program as it is written by a programmer using a programming language and before being converted by a compiler into a form such that its instructions can be understood directly by a computer's CPU (central processing unit); it is generally necessary to have the source code in order to be able to make changes to a program. This ability to freely experiment with and modify the source code, and to do so without disclosing the modifications to outsiders, has been a very important consideration for a number of large organizations3. 25 Reasons to Convert to Linux, compiled by The Linux Information Project via digg
