Expansion Slots
Expansion cards are used to increase and expand a computer’s capability. We can add cards that perform a variety of functions, such as adding more USB, serial, or parallel ports. Communication-based cards can also expand the feature set of the computer through adding a modem or network card. Users who want to play more games may find it useful to add a new video card with better graphics capabilities. Users trying to conserve space could add a TV tuner expansion card to allow the computer to act like a TV to watch cable and record shows like a DVR. Most commonly, though, expansion slots are used to add new ports and features that were not originally available when the computer was made, such as eSATA, FireWire, or USB 3.0 ports.
