Laptop Components: Expansion Cards

We begin our 3.1 discussion with Laptop hardware and their components. For the most part, everything we can do on a full size computer is possible to do on a laptop because they are generally fully loaded. There are some components however that are unique only to laptop/notebook computers.  For example, expansion cards, which are small, credit card-sized cards used to extend a notebooks capabilities.  There are also several types called PC cards or PCMCIA which are older. We’ll discuss the differences between PCMC and PCMCIA that slide into the notebook/laptop in a specific orientation that provide the ability to add on additional features and functions; they use a parallel bus for transmitting information.  We’ll also contrast the Type I, II, and III PC cards in terms of function, size, what their purpose is and which would require an adapter.
