Explain why spinlocks are not appropriate for single-processor systems yet are often used in multiprocessor systems?
A spinlock is basically a loop that constantly checks a condition until it is true. Think of a bunch of kids in the back of a car saying "Are we there yet...are we there yet...are we there yet...". This is a poor implementation for almost any setup, since the lock is wasting processor time that could be doing something more efficient than constantly checking a condition over and over. Also, while the spinlock is running on the processor, the system will be completely unresponsive.

What if your son wants breast?
It's important to have open and honest conversations with your child about their curiosity and feelings. You can calmly explain to your son that breastfeeding is a natural and important process for infants and it is not something that is appropriate for older children. Offer age-appropriate information and reassurance in a loving manner.
What is an appropriate model that has been developed to describe atomic structure?
The Bohr model is an appropriate model that has been developed to describe atomic structure. In this model, electrons orbit the nucleus in discrete energy levels or shells. It helps explain how atoms absorb and emit light energy.
Can you Identify the five refusal skills?
The five refusal skills to resist pressure are: 1) assertiveness (be firm and direct), 2) give reasons (explain your decision), 3) alternatives (suggest other options), 4) repeat (stick to your answer), and 5) avoid (remove yourself from the situation).

Explain in briefly on the Classification of operating system?
Classification of Advanced OS is done as below:Architecture driven systems, and Application driven system. 1. Architecture driven: * Network OS * Distributed OS * Multiprocessor OS 2. Application driven: * Database OS * Real Time OS * Multimedia OS
Explain why implementing synchronization primitives by disabling interrupts is not appropriate in a single-processor system if the synchronization primitives are to be used in user-level programs?
Interrupts are not sufficient in multiprocessor systems since disabling inter rupts only prevents other processes from executing on the processor in which inter rupts were disabled; there are no limitations on what processes could be executing on other processors and therefore the process disabling interrupts cannot guarantee mutually exclusive access to program state.
Explain why interrupts are not appropriate for implementing synchronization?
Because they are completely unrelated things? Synchronization can be implemented with semaphores or mutexes.
