#The CPU pane shows how processes are affecting CPU (processor) activity. Click the top of the "% CPU" column to sort by the percentage of CPU capability used by each process. This information and the information in the Energy pane can help identify processes that are affecting Mac performance, battery runtime, temperature, and fan activity.


#The Memory pane shows information about how memory is being used. As long as memory pressure is not in the red state, macOS has memory resources available.


#The Energy pane shows overall energy use and the energy used by each app. As energy use increases, the length of time that a Mac can operate on battery power decreases.


#The Disk pane shows the amount of data that each process has read from your disk and written to your disk. It also shows "reads in" and "writes out" (IO), which is the number of times that your Mac accesses the disk to read and write data.


#The Network pane shows how much data your Mac is sending or receiving over your network. Use this information to identify which processes are sending or receiving the most data.


#The Cache pane shows how much cached content that local networked devices have uploaded, downloaded, or dropped over time (In macOS High Sierra 10.13.4 or later, Activity Monitor shows the Cache pane when Content Caching is enabled in the Sharing pane of System Preferences). Use the Maximum Cache Pressure information to learn whether to adjust Content Caching settings to provide more disk space to the cache. Lower cache pressure is better. 


You can have a general understanding of your Mac through the above information and you can troubleshoot your Mac and take corresponding measures to solve various problems.
