Answer: d. the time quantum should be as small as possible.
Explanation: Round robin is a CPU scheduling algorithm. If the time quantum is extremely small, number of context switches is very high, round robin scheduling will be same as processor sharing algorithm. Then the algorithm is good. Very large time quantum will make response time of processes too much which may not be tolerated in interactive environment.
Answer is D. 1024
8 bits is enough to represent 256 different numbers. 9 bits is enough to represent 512 numbers. 10 bits can represent 1024 numbers.
Answer:
CREATE FUNCTION exam_eligible_students
RETURN NUMBER AS
num_students NUMBER(15);
BEGIN
SELECT COUNT(STUDENT_ID)
INTO num_students
FROM STUDENT_ATTENDANCE
WHERE ELIGIBILITY_FOR_EXAMS = 'Y';
RETURN (num_students);
END;
Explanation:
exam_eligible_students is a made of name for the FUNCTION to be called.
num_students is a made up name for the RETURN to be called. The RETURN name is referenced in the INTO statement and as the name of the the return in the RETURN line in ().
Answer:
Constructor in the class is the member function that gets into action when any new object gets created in the class ,it gets invoked. It does not have any return type and no void return.
The constructor is used in the class because there is the requirement for the initializing of the new object and then only object can do the functioning in the program.
Answer:
The answer is "new version of application provides more easy to use".
Explanation:
- In computer science, an application is a program, that is installed on the computer. There are many types of application software, that are "gaming software, working software, programming software, etc." At the end of time users want some new things in software to know users need programmer developed new versions of the software.
- The update usually improves the device or service in its current version, whilst an improvement is an entirely new version. Installation is usually free and easy. You also have to wait for updates that are difficult to install.
