Every computer expert managing a network needs to know what's going on in it. Having a detailed inventory of the machines and devices on the network is important. Why is it so important? Because if a network audit is on schedule or a software upgrade is coming, you need to know whether all of the computers are up-to-date to support new systems or if there is additional work to be done before the upgrade.
Keeping a clear and current inventory is not a simple task. Special software network scanning tools will efficiently collect all the information you need and will neatly organize it for your usage.
