What does the 'top' command display in Linux?

The 'top' command in Linux provides a dynamic view of running processes and system usage. It continuously updates in real-time, allowing users to monitor system performance, including CPU usage, memory usage, and the processes currently executing on the system. This dynamic aspect is crucial for system administrators and users who need to track system performance and resource allocation on the fly. The display is interactive, allowing users to sort processes by various criteria and even send signals to processes directly from the interface. This makes 'top' an essential tool for diagnosing performance issues and managing running applications effectively.
