Open Source Vs Closed source operating system. Linux is different from other operating systems in the sense that it is an open source operating system as its source course along with other changes are publicly available. Usually. when the developers of closed source operating systems refuse to share the code, then the third party application developers become hindered. Open source advocates believe that source code should be available to the public so that it can be reviewed, updated, and improved.
Open source software are not considered as a good alternative sometimes because of the possibility of viruses and threats. Another concern is that they want to get profit from what they code or develop. Open source software, on the other hand, may be reviewed by a much larger group of people for faults and improvements can be made quickly, resulting in better software.
