Open source software is open because its source code is accessible to the general public. The code may be examined, modified, and distributed in new iterations or branches by developers. Although the software is free to use, it is frequently impracticable to deploy it without paying implementation or modification costs in order to make it work for your business. Open source licenses come in different forms, but many enable an infinite number of users. Freeware often refers to closed-source software applications that are offered to consumers for no cost, such as Adobe Acrobat or Skype.
