Answer:
Assume that a context switch takes T time. Suggest an upper bound (in terms of T) for holding a spinlock. If the spinlock is held for any longer, a mutex lock (where waiting threads are put to sleep) is a better alternative.
Explanation:
The top limit is to be twice the value of (2xT). Holding the spinlock for a longer time, it will be necessary to put the thread to sleep and get a context switch, so one process awakes the sleeping thread without the need of a second context switch.
In process synchronization, cooperating process can affect or be affected by other processes executing in the system, either directly share a logical address space, both code and data, or be allowed to share data only through files or messages, although concurrent access to shared data may result in data inconsistency. But there are several mechanisms to help the orderly execution of cooperating processes that share a logical address space, so that data consistency is kept.
Answer:
Put option
Explanation:
We have current price 40dollars - strike price 38dollars = $2. The question says the stock is trading at $0.25 per share. Since 0.25 is higher than 0 it is a put option. And the intrinsic value is $2.
The put option gives one the right to sell a particular number of shares at a price that has been set which is referred to as the strike price before a certain date.
Answer:

Answer and Explanation:
The computation of the overhead rate for each activity is as follows;
Overhead rate is
= Respective overhead cost ÷ Respective activity
For Machine setups
= ($202,800 ÷ 2,600 setups)
= $78 per setup
For Machining
= ($364,500 ÷ 24,300 machine hours)
= $15 per machine hour
For Inspection
= ($88,000 ÷ 1,600 inspections)
= $55 per inspection
In this way it is calculated
Jeff's pizzeria can handle 30 orders during the day.It wanted to increase this number,so it started making its delivery boys do minor chores in the kitchen when they were not out for delivery and made some of the chefs pick up customers' calls.This doubled the number of order Jeff's Pizzeria could handle.This approach is an example of <u>Synergy</u>
