How to Check CPU Usage: A Comprehensive Guide for Windows, Linux, and Mac Users

That being said, monitoring the CPU usage on your device is crucial in ensuring the optimal performance of your system. In this article, we will provide you with a comprehensive guide on the ways to check CPU usage in Windows, Linux, and Mac.

For Windows Users:

1. Task Manager: Task Manager is the most straightforward way to check CPU usage on Windows. You can access it by right-clicking on the taskbar and selecting "Task Manager" or by pressing the "Ctrl + Shift + Esc" keys on your keyboard.

Once you open the Task Manager, you will be able to view the current CPU usage in real-time, as well as the usage history over a period of time. In the Processes tab, you can see which processes are currently running and their respective CPU usage. By clicking on the "CPU" column, you can sort the processes according to their CPU usage, helping you identify which processes are using up the most resources.

2. Resource Monitor: The Resource Monitor is a more advanced tool that provides a deeper look into your system's performance. You can access it by opening the Task Manager and clicking on the "Performance" tab. From there, you can click on the "Open Resource Monitor" button at the bottom of the screen.

In the Resource Monitor, you can view detailed information about your CPU usage, including the usage of individual cores, processes, and services. The Resource Monitor also provides a real-time view of disk I/O, network I/O, and memory usage, helping you to diagnose any performance issues.

3. Performance Monitor: The Performance Monitor is a more advanced tool that provides a detailed view of your system's performance, including CPU usage. You can access it by opening the Run dialog box (press the "Win + R" keys on your keyboard), typing "perfmon.msc" into the box, and hitting Enter.

For Linux Users:

1. Top Command: The top command is one of the most popular tools used by Linux users to monitor their system's performance, including CPU usage. To use the top command, simply open a terminal window and type "top" into the command line.

The top command provides a real-time view of your system's performance, including the current CPU usage, as well as the usage of other system resources like memory and disk. You can use the top command to identify which processes are using up the most resources and kill them if necessary.

2. Htop Command: The htop command is a more advanced version of the top command, providing a more user-friendly interface for monitoring your system's performance. To use the htop command, simply open a terminal window and type "htop" into the command line.

In the htop interface, you can view the current CPU usage, as well as the usage of other system resources like memory and disk. Additionally, you can also use the Windows Task Manager to monitor CPU usage. To open the Task Manager, simply right-click the taskbar and select "Task Manager". You can also press the Ctrl + Shift + Esc keys to open the Task Manager directly.

Once the Task Manager is open, you will see a list of running processes and their resource utilization, including CPU usage. The overall CPU usage is displayed at the top of the window, and you can also view the usage of each individual core in the CPU.

For Mac Users

     1. Activity Monitor: Once the Activity Monitor is open, you will be able to see the overall performance of your Mac. The top of the window will show you the CPU, Memory, Energy, Disk, and Network tabs. To check the CPU usage, you need to select the “CPU” tab. Follow the steps to access this tool:

• Launch the Finder and select “Applications”.
• Navigate to the “Utilities” folder.
• Double-click on “Activity Monitor” to launch it.
• 2. Terminal App: The Terminal will show you a list of processes and their corresponding CPU usage. You can also see the overall CPU usage at the top of the Terminal window. To do this, follow these steps:
• Launch the Terminal app.
• Type the command “top” and press enter.
• The Terminal will display the CPU usage information in real time.

Finally, there are also a number of third-party tools available on how to check CPU usage. Some of these tools are designed specifically for system administrators and provide advanced features such as process monitoring, performance analysis, and real-time alerting.

In conclusion, learning how to check CPU usage is an important part of managing the performance of your system. Whether you're using built-in tools like Task Manager or third-party applications, there are a variety of ways to monitor CPU usage and ensure that your system is running smoothly. By keeping an eye on your system's resource utilization, you can take proactive steps to resolve performance issues and ensure that your system is operating at peak efficiency.
