Consider an environment in which there is a one-to-one mapping between user-level threads and kernel-level threads that allows o

ne or more threads within a process to issue blocking system calls while other threads continue to run. Explain why this model can make multithreaded programs run faster than their single-threaded counterparts on a uniprocessor computer.

Explanation:

According to the situation mentioned in the question about the model that can make the multi threaded execution faster as compared with the single threaded counterparts programs because multi-threaded programs have the capability to execute simultaneously in multiple processes.

In this type of system ,the blocking system cannot block the complete execution because kernel thread is present for every user thread .So, if one kernel thread gets blocked , others will still keep running .

Whereas, for uni-processor system , the program has to wait for the input -output operation completion for most of the time.Thus, multi-threaded program can execute faster than uni-processor.

My code get an input of 1900 and it should output not a leap year but it fails first line of code. It should output not a Leap a
marshall27 [118]

Answer:

Explanation:

The code does not fail on the first step since 1900 divided by 4 is actually 475 and has no remainder, meaning that it should return True. The code won't work because the if statements need to be nested in a different format. The correct algorithm would be the following, which can also be seen in the picture attached below that if we input 1900 it would output is not a leap year as it fails on the division by 400 which gives a remainder of 0.75

input_year = int(input())

if input_year % 4 == 0:

   if input_year % 100 == 0:

       if input_year % 400 == 0:

           print(input_year, "is a leap year")

       else:

           print(input_year, "- not a leap year")

   else:

       print(input_year, "is a leap year")

else:

   print(input_year, "- not a leap year")

Step2247 [10]

Answer:

B. Implement a key escrow.

Explanation:

A key escrow can be defined as a data security method of storing very essential cryptographic keys.

Simply stated, key escrow involves a user entrusting his or her cryptographic key to a third party for storage.

As a standard, each cryptographic key stored or kept in an escrow system are directly linked to the respective users and are encrypted in order to prevent breach, theft or unauthorized access.

Hence, the cryptographic keys kept in an escrow system are protected and would not be released to anyone other than the original user (owner).

In this scenario, the Chief Information Officer (CIO) has determined the company's new public key infrastructure (PKI) will not use online certificate status protocol (OCSP). However, the purpose of online certificate status protocol (OCSP) still needs to be addressed. Thus, what should be implemented is a key escrow because the online certificate status protocol (OCSP) is an internet protocol used for maintaining the security of a server and obtaining a digital certificate that has been revoked.
