System Monitor

A system monitor is a software tool that provides real-time information about a computer system's performance, resource usage, and processes. It typically displays metrics such as CPU utilization, memory consumption, disk activity, network traffic, and running applications, helping users and administrators track system health and diagnose issues.

Also known as: Task Manager, Performance Monitor, Resource Monitor, Activity Monitor, SysMon

Why learn System Monitor?

Developers should use system monitors to identify performance bottlenecks, debug resource-intensive applications, and ensure efficient system operation during development and deployment. Common use cases include optimizing code for memory leaks, monitoring server loads in production environments, and troubleshooting slow response times in applications.
