By accessing the source code, you can also modify the free software. You can share it to other users without any restrictions.You can study the free software, how it is developed, how it works and can change their pattern according to your own computing requirement. If you feel any improvement in it, you can also improve it and can share its latest version to public. Many software as antiviruses, adobe reader, flash players, media players, typing tools, etc. are available free of cost on internet.

What is Open Source Software?

Open Source Software looks like free software but it is not same to free software. Some dissimilarities exists between them. Open Source Software is that software although is available to public free of cost along with source code but including a license or security code. It is developed through public cooperation. It also gives permission to users to use, modify, study or share them freely. Sometimes modifications are allowed by license and sometimes not. You can share it to other users specifying the changes you have made, under the original license agreement without any imposing any further restrictions.
