Question

Which of the following is true? I. The 80/20 rule states that 80% of the instruction is executed and 20% of the instruction is generated In von Neumann architecture, external bus is for data memory only II a) Only I b) Only II c) Both I and I are true d) Neither I nor II

Answer 1

Answer:

D) Neither I nor II

Hope it will helpful

Answer 2

Neither I nor II is correct in the given statement.

Explanation:

The 80/20 concept, also known as the Pareto Principle, is an aphorism that states that for any given event, 80 percent of outcomes arise from 20 percent of all causes.

• The given statement 80/20 rule states that 80% of the instruction is executed and 20% of the instruction is generated is not correct as per 80/20 rule.  

The von Neumann architecture was designed to store in the same memory the program and instructions data. The external buses are used to transmit data from one storage unit to another.

• The given statement as the external bus is for data memory only is not correct as per von Neumann architecture.
