Lesson 2: Configuring Expansion Cards
In the previous lesson, we discussed the different kinds of expansion buses. The purpose of these buses is to accept expansion cards. Internal and external computer hardware, such as disk drives and monitors, can be connected to the computer's motherboard by means of these expansion cards. As we learned in earlier lessons, the expansion buses connect to an external data bus. All devices are connected to the same communication bus. In this lesson, we look at how the computer keeps track of each device and controls the flow of data.
