Just like Microsoft Windows has it’s default task manager that can display list of runninng services, utilization of CPU and memory as well as other system resources, Ubuntu / Linux Mint too comes with it’s own task manager. It is termed “System Monitor” and can be easily used to view how much RAM, CPU and what kind of processes are running in an easy to view graphical format.

To view it, go to Menu > System Tools > System Monitor.
