Which statement is True or False about the Windows 11 Operating System (OS)? (i) The OS loads program code directly onto the hard disk for execution, as the CPU can only execute code from permanent storage. (ii) For multitasking, the OS allocates small CPU time slices to processes, rapidly switching between them, a technique known as Time-Sharing.
(i) False, (ii) True
Statement (i) is FALSE. To run a program, the OS loads its code from permanent storage (the hard disk or SSD) into main memory (RAM), not onto the hard disk. The CPU executes instructions directly from RAM, not from permanent storage. RAM is fast, volatile working memory; the hard disk is slow, non-volatile storage. So the claim that the CPU can only execute code from permanent storage is incorrect.
Statement (ii) is TRUE. In a multitasking OS, the CPU is shared among many processes by giving each a small slice of CPU time (a time quantum) and rapidly switching between them via context switching. This gives the illusion that programs run simultaneously, and the technique is known as time-sharing.
Since (i) is False and (ii) is True, the correct choice is (i) False, (ii) True.
