I prepared a short essay [in early 2009] consisting of three paragraphs (and composed of less than 500 words) in compliance with a requirement in an application for admission to the Distance Education (DE) program of Diploma in Computer Science (DCS) in the University of the Philippines (UP) - Open University [UPOU].
I still have a hard copy of the said essay, so I thought it might be helpful for prospective UPOU - DCS applicants to check it out. There is an online copy in Scribd.
Please do check out Google for more information about the "UPOU - DCS" DE program.
