Process Management

5 minutes 5 Questions

Process management is the allocation, scheduling, and management of system resources among running applications or processes. It ensures that the OS operates efficiently by managing these processes. Major components of process management include process creation and termination, process hierarchy, process state transitions, process control, context switching, inter-process communication, and process scheduling. Various algorithms, like First-Come_First-Serve, Round Robin, and the Shortest Job First, help OS in deciding which processes to run and when. Proper process management is important to prevent issues, such as system crashes and deadlocks, while maximizing resource utilization and minimizing response time for user interactions.

What is Process Management?
Process Management is a core operating system function that effectively coordinates the activities of the CPU. It involves process creation, interruption, deletion, scheduling, and synchronization.

Importance of Process Management
Process Management ensures efficient use of system resources, aids multi-tasking, minimizes system crashes, and ensures system stability. It's crucial to understand for successfully maintaining modern computer systems.

How Process Management Works
Tasks are split into smaller processes that are managed independently. The 'Scheduler' controls which process has conditions favorable for execution and grants it access to the CPU. A 'Dispatcher' loads the process for execution.

Answering Questions on Process Management in Exams:
Understanding key terms associated with Process Management is vital: this includes Scheduler, Dispatcher, and Concurrency. Always relate your answers to efficient resource allocation, stable system performance, and better process coordination.

Exam Tips:
1. Make sure you understand and can explain how the Scheduler and Dispatcher work within the context of an operating system.
2. Practice writing out how Process Management helps a system maintain stability and optimize resource use.
3. Be familiar with the ways that Process Management can fall short, leading to system inefficiencies or crashes.
4. Multiple Choice Questions often focus on testing specific knowledge about Process Management, so concentrate your revision here.

Question 1

A user's computer is experiencing slow performance. Upon investigation, you find out that the CPU usage is constantly at 100%. What can be the best solution?

Increase the screen resolution Change RAM frequency Upgrade the computer's operating system Close unnecessary processes and applications

Correct Answer: Close unnecessary processes and applications

Closing unnecessary processes and applications is the best solution when a computer's CPU usage is constantly at 100%. High CPU usage indicates that the processor is being overloaded with tasks, causing slow performance. By closing applications and processes that are not needed, the CPU can focus its resources on essential tasks, thereby improving overall system performance. Increasing screen resolution, changing RAM frequency, or upgrading the operating system will not directly address the issue of high CPU usage and may not provide an immediate performance improvement in this scenario.

Question 2

After upgrading to a new application, a user is experiencing frequent freezing and crashes. What could be the best step to solve this issue?

Reboot the computer Increase the system's virtual memory Add an extra hard drive Check if the new app is compatible with the existing hardware

Correct Answer: Check if the new app is compatible with the existing hardware

The best step to solve the issue of frequent freezing and crashes after upgrading to a new application is to check if the new app is compatible with the existing hardware. Compatibility issues between software and hardware can often lead to instability and performance problems. Rebooting the computer, increasing virtual memory, or adding an extra hard drive may not address the underlying compatibility problem and are less likely to resolve the issue. Ensuring that the new application is designed to work with the user's current hardware specifications is crucial for smooth operation.

Question 3

A computer is running out of storage, but analysis shows that the system has an unusual amount of temporary files. What should a technician do?

Upgrade the graphics card Run disk cleanup to remove unneeded temporary files Defragment the hard drive Disable the Windows search service

Correct Answer: Run disk cleanup to remove unneeded temporary files

The best solution is to run disk cleanup to remove unneeded temporary files. This directly addresses the issue of the system having an unusual amount of temporary files that are taking up storage space. Upgrading the graphics card would not help with a storage issue. Disabling the Windows search service may free up some system resources, but it does not specifically target the problem of excess temporary files. Defragmenting the hard drive can improve performance by reorganizing files, but it does not necessarily free up storage space taken up by temporary files.
