How does the updatelayer function work in ArcGIS?
The UpdateLayer function allows you to replace all layer properties available in the ArcMap Layer Properties dialog box using a layer ( .lyr) file that contains the customizations. Group layers and other sublayers (for example, annotation classes) are treated just like ordinary layers.
How do you change the Order of layers in ArcGIS?
Within a data frame, the layers listed at the top of the Display tab will draw over those listed below them, and so on, down the list. You can easily move layers around to adjust their drawing order or organize them in separate data frames.
Why do you need a layer object in ArcGIS?
The Layer object is essential for managing layers that reside within a map document ( .mxd) or within a layer ( .lyr) file. The layer object provides access to many of the common layer properties found in the ArcMap Layer Properties dialog box and it also provides methods for saving layer files.
Where do I find layer properties in ArcGIS?

Why do you need a basemap layer in ArcGIS?
Basemap layers are a kind of map layer that provides a framework onto which you display your dynamic operational information. Basemap display performance is very fast. Since basemap layers are relatively static and do not change frequently, their display can be computed once and reused many times.
How do I add a basemap layer to a table of contents?
Add a new basemap layer to your map. Right-click the data frame name in the table of contents and click New Basemap Layer. This adds a new basemap layer in your table of contents. The basemap layer behaves much like a group layer in that you can drag content into it.
