Which of the following is not among the properties of child processes created by most of the Operating Systems? A. Computation speed­up B. Priority for critical functions C. Protecting parent processes from errors Correct Answer A, B and C

The correct answer is option 4.

Concept:

A child process is one that is formed in the operating system by a parent process using the fork() system function.

• A child process is often referred to as a subprocessor a subtask.
• A child proces is formed as a clone of its parent process and inherits the majority of its properties. If a child process has no parent process, it was generated by the kernel directly.

Statement A: Computation speed­up.

False, The Parent and Child processes should run concurrently or in parallel; no assumptions should be made about which process should run first.

Statement B: Priority for critical functions.

False, A child process receives the same time quantum as its parent, whereas threads share the parent's time slot. This results in more parallelism than simple threads. For vital functions, the Parent and Child process has the same priority.

Statement C: Protecting parent processes from errors.

False, The new security architecture also allows anti-malware protected services to start protected child processes. These child processes will have the same degree of security as the parent service, and their binaries must be signed with the same certificate that was registered via the ELAM resource section.

Hence the correct answer is A, B, and C.
