<span>Computers don't need system software. System software is used to automate many tasks so the user can achieve more. Actually, one of the ideas of computer programming is to avoid needless repetition. The system software will prepare the computer for the user.</span>
Answer:
Interrupt (INT) helps operating system to stop work on one process and start work on other process using interrupt signals.
Explanation:
Purpose of interrupts:
• Interrupts are useful when an I/O device needs to be serviced only occasionally at low data transfer rate.
• For example, when a peripheral requires the attention of the processor to perform an I/ O operation.
A trap:
• also known as an exception or a fault, is typically a type of synchronous interrupt caused by an exceptional condition
• is a software-generated interrupt.
• For example it's caused by division by zero or invalid memory access.
Can traps be generated intentionally by a user program? Yes.
If so, for what purpose?
• the usual way to invoke a kernel routine (a system call) because those run with a higher priority than user code.
• Handling is synchronous, so the user code is suspended and continues afterwards.
• In a sense they are active - most of the time, the code expects the trap.
Answer:
10 or 22 or 15 or 40
Explanation:
In the second for loop[for (int k = 1; k < arr[0].length; k++)], k starts from 1 instead of zero. That means that it doesn't read the first value of every row when finding num.
So if num was any of the above values, the program wouldn't work. I had the same question, and the answer for mine was 15.
