Which abbreviation stands for Controller Area Network?

• A. Central Area Network
• B. Control Area Network
• C. CAN
• D. Computer Area Network

Answer: (C)

Abbreviations are formed by taking the initial letters of each word in a name. For Controller Area Network, that yields CAN. This is the standard, widely recognized acronym for the fieldbus used in vehicles and embedded systems to let multiple controllers and devices communicate reliably without a central host. The other phrases don’t reflect the established terminology, so they aren’t the correct abbreviation. In practice, CAN (CAN bus) is the term you’ll see in automotive and industrial networking contexts.
