[amp_mcq option1=”main storage” option2=”primary storage” option3=”floppy disk” option4=”disk drive E. None of the above” correct=”option1″]
The correct answer is A. main storage.
Main storage, also known as primary storage or RAM (random access memory), is the computer’s short-term memory. It is where the operating system and all currently running programs are stored. Main storage is much faster than secondary storage, such as a hard drive, but it is also much more volatile. This means that when the computer is turned off, everything in main storage is lost.
Floppy disks, disk drives, and other forms of secondary storage are used to store data permanently. This data can be accessed even when the computer is turned off. However, secondary storage is much slower than main storage, so it is not used to store the operating system or other programs that need to be accessed quickly.
In conclusion, the operating system software has to stay in main storage because it is the computer’s short-term memory and it is much faster than secondary storage.
