1. Three threads are created by a process with pid 10. How many threads of execution are there after the creation assuming nothing has time to terminate?
2. Where are the PCBs for processes stored?
(i) In an individual process’s memory in user-space.
(ii) In a kernel data structure.
(iii) Managed by some user-space OS service.
Homework Answers
Answer 1. Threads are basically parts of a process. These parts work efficiently by dividing virtually by distributed computing concepts. Here three threads are created from a process, there it may be constant or can be customized for more and less.
Answer 2. The process control block contains some specific terms with values related to a process. The PCB stores some values in it. And, this Process Control Block must be stored in a memory location with limited privileges to a user in user-space. This should be accessible by a user easily.
In some cases, the Process Control Block is kept at the starting point of the kernel stack for security reasons.

Write separate programs, as described below, that create 7 processes according to the parent/child hierarchy shown on the right, where P0 is a parent to P1 and P2, etc.Before each parent terminates, it must wait until all of its children have terminated.When created, every process should print its index (0 – 6), its PID, and its parent’s PID. Each process does no work and prints a message indicating when it is done. In your report, include your program output and...

There is a problem anticipating and testing for all potential types of non-standard inputs that might be exploited by an attacker to subvert a program. 2. Without suitable synchronization of accesses it is possible that values may be corrupted, or changes lost, due to over-lapping access, use, and replacement of shared values. 3.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
