Answer:
Increasing
Explanation:
Generally in economics, opportunity cost is the benefit that a person, a business, or an investor forgo or missed when he chooses one alternative instead of the other.
Under production, opportunity cost occurs when a producer sacrifice the production of one for the production of another good. Using good X and Y as examples, opportunity cost is measured by the number of units of good Y that the producer gives up in order to produce one or more units of good X.
In the question, the two products used are computers and DVD. The -15, -18 and -20 implies that producing an extra unit of computer by moving from point A to point B, point B to C, and point C to D, 15, 18 and 20 units of DVD respectively have to be given up.
Since 20 is greater than 18 and 18 is also greater than 15, it therefore implies as we produce more computers, the opportunity cost, which are the number of DVDs given up at each point, are increasing.
I wish you the best.
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.
