What does the 'top' command specifically provide?

• A. Real-time information about inactive processes
• B. Real-time information about the most active processes
• C. Updates APT database
• D. Installs a new software package

Answer: (B)

The 'top' command is a powerful utility in Linux that displays real-time information about the most active processes currently running on the system. It provides a dynamic listing of processes sorted by CPU usage, memory usage, and other important factors. This allows users to monitor system performance, identify resource-heavy applications, and manage processes effectively. The output includes key information such as process IDs (PIDs), user ownership, CPU usage percentage, memory consumption, and the commands that initiated those processes. By presenting this data in real time, 'top' helps users and system administrators make informed decisions about resource allocation and troubleshooting system performance issues. The other options, while related to system and process management, do not accurately reflect the functionality of the 'top' command.
