The Pareto Principle, commonly referred to as the 80/20 rule, states that 80% of the effect comes from 20% of causes. Or, in terms of work and time management, 20% of your efforts will account for 80% of your results.
Answer:
Variable Where Declared
In Sub1 :
A Sub1
Y Sub1
Z Sub1
X Main
In Sub2:
A Sub2
B Sub2
Z Sub2
Y Sub1
X Main
In Sub3 :
A Sub3
X Sub3
W Sub3
Y Main
Z Main
Explanation:
In static-scoped languages with nested subprograms, the declaration of a variable is checked with the subprogram, if it is not found, it check within the parent method that called it, it continue until it find a declaration, if no declaration is found, it display an error.
In Sub1, a, y, z is declared there while the declaration of x is found in main.
In Sub2, a, b, z is declared, declaration of y is found in sub1 and declaration of x is found in main.
In Sub3, a, x, w is declared while the declaration of y, z is from the main.
The success on the ability
Answer:
2 x 10⁵ bytes per second
Explanation:
Given:
MIPS rate = maximum speed of CPU to execute instructions = 10 million instructions per seconds
number of instructions required to transfer 1 byte using interrupt driven I/O = 50
Maximum number of bytes that can be transferred in 1 second = MIPS rate / number of instructions for 1 byte
=> max number of bytes = 10 million / 50 = 10 x 10⁶ / 50 = 2 x 10⁵
which is less than the maximum transfer rate of memory = 100 million bytes per second
So, maximum data transfer rate during I/O operations by using interrupt-driven I/O is 2 x 10⁵ bytes per second
