Question

Which of the following bus can easily upgrade the system hardware?

(a) control bus

(b) data bus

(c) VMEbus

(d) bus interface unit

The question was posed to me during an internship interview.

This intriguing question originated from Operating Systems in chapter Real Time Operating systems of Embedded Systems

Answer 1

The correct option is (c) VMEbus

To explain I would say: The software can be easily moved from one system to another which is more important for designing embedded systems, especially for those which use an industry standard bus such as VMEbus, in which the system hardware can be expanded or upgraded.
