Computers consist of numerous elements, both hardware (which is comprised by the components that are tangible objects) and software (such as programs, services, processes, protocols).
System information viewers provide users the possibility to analyze these components to allow users to check their performance or to repair their issues.
Alternatively, one may also rely on these applications to verify compatibility with other components.
These software solutions collect data related mainly to hardware devices, but they might also include software summaries.
