Answer:
When designing a cache, you have to consider this things:
If the cache has a bigger block size may have a lower delay, but when miss the miss rate will be costly. If an application has high spatial locality a bigger block size will do well, but programs with poor spatial locality will not because a miss rate will be high and seek time will be expensive.
Answer:
The expressions in each part of an AND or OR expression use <u>Short Circuit</u> evaluation; that is, they are evaluated only as much as necessary to determine whether the entire expression is true or false.
Explanation:
Logic operations follow different type of evaluation methods that can be short circuit or open circuit evaluation. In short circuit evaluation if first operand of the expression is true or false in OR or AND operation respectively, the result will found as true or false without checking the second operand of the expression. This is called Short Circuit Evaluation.
In OR operation, If first operand is true it means that the result of the expression is true without knowing that the other operand is true or false. In AND operation, If the first operand is False, the result will found as False without knowing that whether the 2nd operand is true or false.
This Mechanism is called Short Circuit Evaluation.
A CPU is the electronic circuitry within a computer that carries out the instructions of a computer program by performing basic arithmetic logical, control and input/output operations specified by the instructions.
Knowing this, the answer is both C - That it coordinates the flow of instructions and data within computers, And A - That a control unit performs arithmetical and logical computations.
If you can only select one answer, I'd personally go with A.
There are some function which can be performed with database but not with a spread sheet, these functions include:
1. Enforcement of data type.
2. Support for self documentation.
3. Defining the relationship among constraints in order to ensure consistency of data.
Wouldn’t be A, C. When editing a word document it would be B and when just opening one from someone it would be D. This question doesn’t give a brief explanation of what’s happening. Can you give more information or is that all of the question?
