1. A method executed on a mobile computing device for identifying a plurality of IT components, comprising: acquiring, by the mobile computing device, an image containing at least a portion of a first IT component and at least a portion of a second IT component, the first IT component containing a first one or more IT components, and the second IT component containing a second one or more IT components; locating in the image, by the mobile computing device, a first identification marker on the first IT component, the first identification marker representing first information about the first IT component and first additional information about the first one or more IT components contained in the first IT component; determining, by the mobile computing device, an identity of the first IT component based on the first information represented by the first identification marker; determining, by the mobile computing device, one or more identities of the first one or more IT components contained in the first IT component based on the first additional information represented by the first identification marker; locating in the image, by the mobile computing device, a second identification marker on the second IT component, the second identification marker representing second information about the second IT component and second additional information about the second one or more IT components contained in the second IT component; determining, by the mobile computing device, an identity of the second IT component based on the second information represented by the second identification marker; determining, by the mobile computing device, one or more identities of the second one or more IT components contained in the second IT component based on the second additional information represented by the second identification marker; displaying, by the mobile computing device, the image; overlaying, by the mobile computing device, indicia of at least the identity of the first IT component on the first IT component in the image; and overlaying, by the mobile computing device, indicia of at least the identity of the second IT component on the second IT component in the image.
