It refers to a running program.

What is the main function of the Process Control Block (PCB) in process management?

• To contain the list of all running processes

• To terminate and start processes

• To contain information about a single process

• To control processes

Processes can create other processes by running​ (a)   . The process that creates other processes is called​ (b)   , and the newly created process is called​ (c)   .

• fork()
• parent process
• child process
• merge()
• descendant process
• spawn()
• ancestor process
• exec()

A(n) ​ (a)   is like a smaller unit of a process.

• thread
• instruction
• subprocess

It is a problem that refers to two or more parallel processes simultaneously accessing and changing the same data. In other words, the order of manipulation of the data affects the result of execution.

• Race Condition

• Lack of Permission

• Lockout

• Parallelism

In order to combat race conditions, we use process synchronization. Reorder the following sections of a process code starting from the first to the last section.

• critical section

• exit section

• entry section

• remainder section

Which of the following isn't a required condition to solve the critical section problem?

• Speed

• Mutual Exclusion

• Progress

• Bounded waiting

It is a synchronization tool that is essentially just a variable that can hold one of two values: "wait" or "signal". This variable is used to let other waiting processes know whether it's safe to enter the critical section.

• Program Counter

• Conductor

• Pointer
• Semaphore
