Understanding Interface Technology

The heart of any computer is its processor. For this processor to be capable of doing anything, it has to have data on which to operate. There are many ways in which data is moved into, out of, and within your Mac. Just to use a Mac, you do not need to understand the various technologies involved in data transfers. However, if you add enhancements to your machine—whether they are external peripherals or internal system upgrades—you do need to understand these technologies.

In this chapter, you will gain a fundamental understanding of the various input and output technologies your Mac uses to move data. This understanding will help you when the time comes to add devices or other improvements to your system.
