Answer 1

Correct Answer - Option 1 : Internet explorer

The correct answer is Internet explorer.

• Internet Explorer is not open-source software.
  •  Open-source software is a type of computer software in which source code is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software to anyone and for any purpose.
  • Open-source software may be developed in a collaborative public manner.
  • The licensee can either charge a fee for this service or work free of charge.
  • The most popular licensing system is GNU General Public License (GNU GPl, or GPL).
  • Under GNU GPL, the licensees may not ‘close’ versions.
  • The licensee may modify copy and redistribute any derivative version, under the same GPl license.
  • The DOS and Windows are the proprietary software of Microsoft. 

 

• The distribution terms of open-source software must comply with the following criteria: 
  • Free Redistribution:
    • ​ No restriction on any party from selling or giving away the software as a component of an aggregate software distribution containing programs from several different sources.
  • Source Code:
    • The program must include source code and must allow distribution in source code as well as compiled form.
  • Derived Works:
    • ​ The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software.
  • Distribution of License:
    • ​ The rights attached to the program must apply to all to whom the program is redistributed without the need for execution of an additional license by those parties.
