Access control: Access control is a security technique that controls the admission of workers into trustworthy areas of the organization. It is maintained through a collection of policies, programs to carry out those policies, and technologies that implement the policies. It is an important concept in security that reduces risk to the business or organization. It is divided into two types are, physical access control, and logical access control.

Consider a system that uses a fixed-partition scheme, with equal partitions of size 2" bytes, and the main memory has 2¹8 bytes. A process table is maintained with a pointer to the resident partition for each resident process. How many bits are required for the pointer in the process table? Show all your steps.

Use the same semaphore notation shown above to describe how we can ensure the execution order of the following process execution graph: P6 P2 P7 P1 P3 P4 P5 Use all of the following semaphores in your answer: s1=0; s2=0; s3=0; s4=0; s5=0; s6=0;
