Answer:
True is the correct answer for the above question.
Explanation:
- When any document file is opened then every point has some particular address. so there is a pointer which states that where the read operation and the write operation is going on.
- When any person writes any program to read a file or write a file then there is a need for some variable that is pointed for the reading and the write operation.
- The document which is used for the write data or read data is also designed and maintained by some software.
- Hence we can say that there are needs of some variable that point the operation of the file and it is also stated from the above question. Hence the above question statement is a true statement.
Answer:
4 is the correct answer for the above question.
Explanation:
- If the if-else sequence has 4 blocks then it will be designed like if, else-if, else-if and then else which made 4 blocks which are as follows:-
- The first block is an if block.
- Then the second block is an else-if block.
- The third block is also else-if block and
- The fourth block else blocks.
- So there is a need of 4 value (one value for each case) to test the application which is defined in the above scenario.
- It is because when the first if statement is false then the first else-if statement is executed and when the first else statement is false then the second else-if statement is executed and when it is false then the else statement will executed.
Answer:
It would be correct to say that out-of-order makes a machine's performance more sensitive to branch prediction accuracy.
Explanation:
This can be explained as when a machine is out-of-order, in that state the execution holds importance in prediction accuracy, any increase in these results in rate of prediction near about 25% for the single-issue operating in-order. This is due to the reason that some of the predictions are required for the global pattern history. Most recent outcomes are recorded in the register and for a 4-way machine which is out-of-order, accuracy is very poor as a result of the delay of the branch history for next prediction.
