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
