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.

Explanation:
Formulas!D11: =C11*0.0675
4 / 7 (57.1%)
Feedback:
[-2] The formula in cell D11 does not reference the sales tax rate
[-1] The tax rate reference is not absolute
Copy the formula you used in cell D11 down to calculate the sales tax amount for the remaining transactions.
1 / 1 (100.0%)
Feedback:
Construct a formula in cell E11 to calculate the total amount for transaction 578. Be sure to appropriately reference the transaction amount in cell C11 and the sales tax amount in cell D11 so that you can reuse your formula to calculate the total for the remaining transactions.
Formulas!E11: =SUM(C11:D11)
6 / 6 (100.0%)
Feedback:
Copy the formula you used in cell E11 down to calculate the total for the remaining transactions.
2 / 2 (100.0%)
Feedback:
Use the SUM function to calculate the “Grand Total” in for all transactions in cell E24.
Formulas!E24: =SUM(E11:E23)
4 / 4 (100.0%)
