Computer Inventory: The Softwares

Hi,

This is related to the softwares used for physical inventory of computer devices in a company (Note: The computer devices can be all desktops, all laptops, all servers, all network devices, all printers, etc). Most company do the physical inventory of their computer devices at least Once a year (It is very helpful for the accounting department)

I forgot the name of the SOFTWARE used to get all the INFORMATION of the above devices (Sucah as Its Operating System, application softwares installed, serial numbers, etc)

My questions:
1)      First: What is the name of the above software? (It was used between 10 – 15 years ago)
2)      Second: What other softwares have been using for the Inventory of computer devices now?

Thank you
