Chapter 28. Understanding Input and Outp... > Understanding Interface Technology

Understanding Interface Technology

The processor is the heart of any computer. 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. To use a Mac, you do not need to understand the various technologies involved in this transfer of data among the various components of the system, such as the processor. However, if you add enhancements to your machine—whether they are external peripherals or internal system upgrades—you do need to understand these interface technologies.

NOTE

The term interface refers to the location at which two devices are physically connected. The term also refers to the technology that particular interface uses. For example, when someone refers to devices that use a USB interface, this implies that a specific physical connector is used (a USB connector) over which data following the USB specification is communicated.
