5. A concurrent work of two computers is represented by the diagram: write(a,2), read(b,1), computer 1: + external time write(b,1), read(a.0), computer 2: Is this execution sequentially consistent? If yes then arrange the operations into a sequence, so that their execution in the order of their occurrence in this sequence, yields the same result as the concurrent execution and the conditions of sequential consistency are fulfilled. The sequence (if it exists):

The implementation of instruction set architecture has amply shown the principle of abstraction in computer structure and design. It has the ability to handle complexity while hiding extraneous components. Give a definition of abstraction and describe its two components.
In a single-machine setting, how does a computer perform multitasking? A real-world scenario and a real-time machine to explain the issue?
Abstraction is a concept in computer organization and architecture that is clearly demonstrated by the implementation of instruction set architecture. It copes with complexity and hide unneeded details. Briefly discuss two aspects of abstraction.
In what scenarios might "priority-based" concurrency control be implemented?
