  3. Filter and Analyze:
    • Use commands like grep to filter specific processes or kill to terminate a process if needed.

V. Common Mistakes

A. Terminating Critical System Processes

Avoid terminating processes unless you’re certain they are unnecessary. Terminating critical system processes can lead to system instability.

B. Ignoring Resource Usage

Regularly monitor resource usage to identify processes consuming excessive CPU or memory, as this may impact system performance.

C. Neglecting Security Considerations

Be cautious about unfamiliar or suspicious processes, as they may indicate malware or security threats. Regularly update antivirus software.

VI. Troubleshooting Running Processes

A. Research Unknown Processes

If you encounter unfamiliar processes, conduct online research to identify their purpose and legitimacy.

B. Optimize Startup Programs

Review and manage programs set to launch at startup. Disable unnecessary startup programs to improve system boot times.

C. Update Software

Outdated software may have vulnerabilities. Regularly update applications and your operating system for improved security.

VII. Conclusion

Checking what’s running on your computer is a fundamental practice for maintaining performance, troubleshooting issues, and ensuring security. Whether you’re on Windows or macOS, using graphical interfaces or command-line tools, understanding your running processes empowers you to optimize your computer’s functionality.
