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.
Answer:
Following are the solution to this question:
Explanation:
Some of the data is missing in the question, which is defined in the attached file. Please find it.
Follows are the formula which is used in the question:
- EmployeeAnalysis Worksheet IF(C5>49,"Certified","Not Certified")
- Transactions Worksheet IF(F10="No","",0.07)
In the first condition, it checks "C5" is greater than 49 if the condition is true, it will give "Certified" otherwise, it will give "Not Certified".
In the second condition, it checks "F10" is equal to "No" if the condition is true, it will give a blank or space otherwise, it will give "0.07".
Answer:
Disadvantages of Batch Operating System:
- The computer operators should be well known with batch systems.
- Batch systems are hard to debug.
- It is sometime costly.
- The other jobs will have to wait for an unknown time if any job fails.
Well if your talking about physically you could get some compressed air and blow it out. Or if your talking about performance you could try to re-install the os you have on it or replace the hdd with a ssd or higher performance hard disk for it to run like new. :)
