Top command output can be read in the following way:
1. The first line of the output gives you an overview of the system resources. It shows the current system time, how long the system has been running, how many users are currently logged in, the system load averages, and the total number of tasks running on the system.
2. The second line of the output is the list of tasks currently running on the system. Each process is listed with its process ID, the user who owns the process, the CPU and memory usage of the process, and the command that launched it.
3. The third line of the output shows the total CPU usage for the system, broken down into user, system, and idle time.
4. The fourth line of the output shows the total memory usage for the system, broken down into total memory, used memory, and free memory.
5. The fifth line of the output shows the swap space usage for the system, broken down into total swap space, used swap space, and free swap space.
