Java Multithreading and Parallel Programming Masterclass - What Is a Process?

The video tutorial explains the concept of processes in an operating system, detailing the process lifecycle, including states like new, ready, running, waiting, and terminated. It covers the role of the scheduler and preemption, using examples of single CPU core management and preemptive multitasking. The tutorial also discusses the process control block, which stores essential information about processes.

What is the primary role of the operating system in relation to processes?

• To store all data in the CPU

• To execute all programs simultaneously

• To manage and schedule tasks

• To compile programs into binary files

Which state does a process enter when it is first created?

• Running

• Ready

• New

• Terminated

What is the role of the scheduler in an operating system?

• To compile programs into executables

• To manage memory allocation

• To terminate processes

• To select processes for execution on the CPU

What is the term for the operating system's ability to interrupt a running process to allow another process to run?

• Scheduling

• Multithreading

• Preemption

• Context switching

What is the purpose of a time slice in preemptive multitasking?

• To allocate memory to a process

• To compile a process into an executable

• To determine the priority of a process

• To limit the time a process runs on the CPU

How does preemptive multitasking benefit user-oriented operating systems?

• By ensuring responsiveness through frequent context switches

• By reducing the number of processes in memory

• By eliminating the need for a scheduler

• By increasing the speed of long-running processes

Which of the following is NOT stored in a Process Control Block?

• File descriptors

• CPU architecture

• Unique ID

• Process state
