27 a. S – Open source software/ perisiansumberterbuka T- Proprietary software/ perisianhakmilik
b. Differences
S- OPEN SOURCE SOFTWARE T-PROPRIETARY SOFTWARE
Open source usually comes without warranty and after sales
support should the software fail or malfunction
software offers a stable system with support if the software fails
or malfunctions.
The source code are available to users and they have the rights to modify them.
Customising the software is nearly impossible because when users buy proprietary software
will receive binary version of the program, not the code as the
code is the maufacturer’s trade secret
