Checking Memory Usage on Your Computer

To check the memory usage on your computer, there are several methods you can use depending on your operating system. Here are some common ways to do it:

Windows

1. Using Task Manager

  • Press Ctrl + Shift + Esc to open the Task Manager directly.
  • Alternatively, right-click on the taskbar and select "Task Manager" from the context menu.
  • In the Task Manager window, click on the "Performance" tab.
  • Under the "Memory" section, you will see the current memory usage statistics.

2. Using Resource Monitor

  • Press Windows Key + R to open the Run dialog box.
  • Type resmon and press Enter to open the Resource Monitor.
  • In the Resource Monitor window, click on the "Memory" tab.
  • You will see detailed information about the memory usage on your computer.

macOS

1. Using Activity Monitor

  • Open the Applications folder and navigate to the Utilities folder.
  • Double-click on the "Activity Monitor" application to launch it.
  • In the Activity Monitor window, click on the "Memory" tab.
  • You will see real-time memory usage statistics for your Mac.

2. Using Top Command

  • Open the Terminal application.
  • Type top -o rsize and press Enter to display a list of running processes sorted by resident memory size.
  • The "RES" column shows the current resident memory usage for each process.

Linux

1. Using Top Command

  • Open the terminal or command prompt.
  • Type top and press Enter to display a dynamic real-time view of running processes.
  • The "%MEM" column shows the percentage of memory used by each process.
  • Press Shift + M to sort the processes by memory usage.

2. Using Htop

  • Install the htop package if it is not already installed (e.g., sudo apt-get install htop for Debian/Ubuntu).
  • Type htop in the terminal and press Enter to launch the htop interface.
  • The htop interface provides a more user-friendly view of memory usage compared to the default top command.
  • Use the arrow keys to navigate through the processes and view their memory usage details.

These are some common ways to check memory usage on different operating systems. Choose the method that works best for you based on your specific needs and preferences.
