It may have a name associated with it ... such as Macintosh (or Mac), Dell, IBM, Gateway, or any of a myriad of names depending where you live and what you decided to buy. No matter what name is associated, all desktop Personal Computers (or PCs) have a few basic components that are common. Laptop systems have the same array of components but they are usually not accessible like in a ... (view more)
