The inspector will inspect many different

The inspector will inspect many different systems and items in the property and will prepare a report for you to help you determine the general over-all well-being of the property. Inspections have different rates based on the size of the property and the depth of their inspection. If they provide the report to you on the spot, their fee tends to be higher.
Just remember when selecting your inspector that, like most things in life, you get what you pay for. I remember a client once who was investing in a tri-plex for close to one million dollars.
