Instruction set architecture is a great example of the use of abstraction in computer design and organization. It can process a large amount of data while hiding the irrelevant details. In a few words, describe abstraction and name two of its distinguishing characteristics.

The execution of instruction set architecture is an excellent illustration of the use of abstraction in computer architecture. Utilising this instrument could reduce the time and effort required to complete a task. Define "two dimensions of abstraction" and "three dimensions of abstraction."

The distinction between a scalar processor and a superscalar processor might perhaps be better understood with the assistance of diagrams. Processing data at a superscalar level is a far more challenging endeavor than processing data at a scalar level. The superscalar processor is now being plagued by two different issues.

The widespread adoption of instruction set architecture is a resounding endorsement of the value of abstraction in computer architecture. It's capable of processing intricacies and masking irrelevant information. Please explain what abstraction is and provide two characteristics that characterise it.
