what are the minimum requirements of a good computer??

This is what I would advice my clients - if you have the money, buy the best at that moment so the technology can last you up till 5 years at least. If you're on a budget, just buy whatever that's needed, the basic functions which you require. If you have some extra, buy something that's upgradable. One can never place a universal minimum requirement as everyone's needs are different

These days the standard configuration of a computer must be: 2 Gb Ram 240 GB Hard Disk Intel Core 2 Duo processor Cd/DVD combo writer Wifi enabled webcam
