This is not a very clear question, so it is necessary to break down the question to make it more manageable and firstly define what a computer based information system is.
A computer-based information system (CBIS for short) is an information system in which the computer plays a major role.
Next we need to determine what the components of a CBIS are. Firstly there is the hardware, which is the computer itself, often referred to as the CPU. Next there is the software, which is what supports the hardware. Then there is the data that are the facts that the computer uses to make "decisions”. Lastly there are the procedures and people who make the procedures.
I would advise that you use the many forums online that help people with their queries about computers and IT. Such forums include www.computerforums.org, www.computerforum.com and www.computerhope.com. These will have people on line that will be able to assist you or at the very least point you in the right direction of someone else that will be able to help.
If this were an exam or coursework question I would advise that you seek help by using the resources available to you. The library may have books on the subject or ask for help from your tutors who are paid to help you and assist you in your studies.
Wikipedia is also a great source for people who are looking for a detailed definition of what PMS is. Use the search section on www.wikipedia.org to benefit from this extensive database of free knowledge.
