[amp_mcq option1=”is a method of memory allocation by which the program is subdivided into equal portions, or pages and core is subdivided into equal portions or blocks.” option2=”consists of those addresses that may be generated by a processor during execution of a computation.” option3=”is a method of allocating processor time.” option4=”allows multiple programs to reside in separate areas of core at the time. E. None of the above” correct=”option4″]
The correct answer is: D. allows multiple programs to reside in separate areas of core at the time.
Multiprogramming is a method of running multiple programs on a computer at the same time. This is done by dividing the computer’s resources, such as memory and processing time, among the programs. This allows users to run multiple programs at once, without having to wait for one program to finish before starting another.
Option A is incorrect because it describes paging, which is a method of memory management. Paging is a way of dividing a program’s memory into smaller pieces, called pages, so that they can be stored in different parts of memory. This allows the computer to use memory more efficiently.
Option B is incorrect because it describes the address space, which is the set of all addresses that a program can access. The address space is determined by the size of the program’s memory and the amount of memory that is available on the computer.
Option C is incorrect because it describes timesharing, which is a method of allocating processor time. Timesharing is a way of dividing the computer’s processing time among multiple users, so that each user has a turn using the computer.
Option E is incorrect because it is not a valid option.
In conclusion, the correct answer is: D. allows multiple programs to reside in separate areas of core at the time.
