What is the difference between an interrupt and a trap quizlet?
An interrupt is a hardware-generated change-of-flow within the system. A trap is a software-generated interrupt.
What is the purpose of interrupts what are the differences between a trap and an interrupt can traps be generated intentionally by a user program if so for what purpose?
A trap is a software-generated interrupt. An interrupt can be used to signal the completion of an I/O to obviate the need for device polling. A trap can be generated intentionally by a user program. It can be used to call operating system routines or to catch arithmetic errors.
What is the difference between exception and interrupt?

Synchronous traps are caused by the actions of an instruction. The trap stimulus in this case either occurs internally to the processor or is from an external signal that was provoked by the instruction.
Is system call a trap?
System calls are accomplished by moving parameters to registers and then calling int 2e to trap into the kernel. Exceptions and interrupts, whether arising from external events, internal faults, or software generated using the int instruction, are vectored throught Interrupt Descriptor Table, the IDT.
Is blocking a trap?
The trap block is a run blocking assignment that pulls a blocker to the play side of the formation to block an uncovered defender. Most of the linemen block down in one direction, while the trap blocker flows in the opposite direction toward the defender.

Does a running trap need a vent?
You need a vent for EACH device or you will siphon the other traps when you run the WM. You may also find that code would require you to make the drain line larger if you add other things to it. There’s a limit, based on the drain line diameter, how far the trap can be from the vent.
Does condensate drain need a trap?
Does a condensate drain need a vent? As long as the condensate drain is connected to the home’s plumbing, a trap is needed to prevent the sewer gas from entering the space.
How deep should the condensate drain trap be?
If a unit were to be operating at minus 6 inches WC maximum negative plenum pressure then the trap height, per the guidelines shown in Figure 1a, requires 7 + 3½ + 1½ + 1 inches of height from under the floor or about 13 inches below the floor level.
Where can I drain my condensate line?
You’ll find a white PVC or copper pipe located near your outdoor unit—this is where the drain line ends. Near your indoor unit, you’ll find a vertical PVC pipe with a cap on it, which acts as the access point for the condensate drain.
How do I clear my AC drain pan?
Here’s a step-by-step guide on how to clean your drain line with vinegar and keep everything operating at peak performance.
- Turn off your air conditioner.

- Let the solution sit for 30 minutes.
- Repeat each month.
Is it safe to pour bleach down AC drain?
It’s going to corrode! Using bleach or vinegar can be especially risky if you think your AC drain line is clogged. If the drain line is clogged, the corrosive mixture will simply back up in your drain line and flow into your drain pan, which in turn can damage your evaporator coil.
