Answer:
a. cryptographic hash function
Explanation:
A cryptographic hash function is a hash function that is suitable for use in cryptography. It is a mathematical algorithm that maps data of arbitrary size to a bit string of a fixed size and is a one-way function, that is, a function which is practically infeasible to invert.
It usually takes two years to complete and tends to focus on technical training would be the best answer
Proactive designing i think
Answer:
See Explaination
Explanation:
Separating this critical section into two sections:
void transaction(Account from, Account to, double amount)
{
Semaphore lock1, lock2;
lock1 = getLock(from);
lock2 = getLock(to);
wait(lock1);
withdraw(from, amount);
signal(lock1);
wait(lock2);
deposit(to, amount);
signal(lock2);
}
will be the best solution in the real world, because separating this critical section doesn't lead to any unwanted state between them (that is, there will never be a situation, where there is more money withdrawn, than it is possible).
The simple solution to leave the critical section in one piece, is to ensure that lock order is the same in all transactions. In this case you can sort the locks and choose the smaller one for locking first.
When permanent magnets of a motor are replaced with more powerful ones, the motor rotation will increase. This is because there is more electricity being generated.
