Linux Task Manager is one of the essential tools that help you to find out the details of resource usages (CPU/RAM) by any particular software or even the system itself.

Just like in other operating systems task managers are so useful to Linux users since as an operating system it has mistakes too. Some are GUI based, and some are CLI based.
