Depends on the context. As an example, for a physical, real-world piece of art it would be a document drafted by an expert certifying that the artwork is real and genuine, and made by the artist who made/signed the painting. It would also contain contact information for the person who certified the artwork. Now that doesn't mean the certificate is always right, it's actually quite easy to produce fake COAs.

For a computer, most specifically for the Windows operating system, this will be a sticker with a serial number showing that the copy of Windows is genuine and has a valid license. For a computer in which Windows comes pre-installed, this will generally be found somewhere on the side of the computer case.
