The primary difference between the New and the simplified BSD License is that simplified BSD license emits this clause.
(iii) GNU General Public License:
The General Public License are copy the software, Distribution, charge a fee, change the code base.
(iv) GNU Lesser General Public License:

GPL. requires any other project or source that is using the project under GPL also be licensed as GPL: GPL licensed code can't be used for paid and proprietary software.

(i) There are many open source softwares. So, we can select and use any software that suits our needs.
(ii) The complete options of the software can be used without any cost and restrictions.
(iii) We can share our ideas with the team. write the required code and share it with many.
(iv) As we can identify the programming techniques of group members, we can learn many ideas and make our program writing skills more efficient.
(v) The coding in open source software are being groomed by many enthusiastical members of the groups. So, if we report problems that we have in the program they are quickly mended by the group's effort.
(vi) As we can make changes to the open source software, we can add the most required features in the software.
(vii) Many open source software are very user friendly.
