What is the difference between proprietary and open source software? What considerations should be made when a business selects either software.

Proprietary application software is software that addresses specific or unique business need for a company whereas open source software is software made available in source code form at no extra cost. A business should choose proprietary software if it is a firm that in need of unique and specific software, if not, it should just obtain the general software, open source software as it is the cheaper alternative. open source software leaves the purchaser with the alternative of editing the source code and hence customising the software to suit certain needs, and the lack of necessity of a license leaves the individual free to distriute the product.

What are some of the legal issues involved in acquiring and using software in most businesses/organizations?

Copying software is illegal. The Software Publishers Association (SPA) has stated that software piracy costs software vendors around the world approximately $15 billion. in order to use propriety software the business must ensure that it is not using it illegally, this is done by obtaining a license. however the software must not be distributed. nonetheless, open source software is free to all and can be distributed to all people.
