A+ Exam Cram Naming Conventions

The A+ Exam Cram 6th Edition uses very particular naming conventions. I spent a lot of time deciding on these and ultimately went with what is used by the organizations and corporations that develop the devices that use these naming conventions including PCIsig, SATA International Organization, Intel, Western Digital, USB.org, and D-Link to name a few. The following list shows the naming conventions used in the A+ Exam Cram 6th edition and A+ Exam Cram Practice Questions 5th edition.

- When dealing with data as it corresponds to internal devices such as hard drives, motherboards, PCIe, CPUs and the like:
