Definition: The word "em" refers to a web address, specifically it appears in the header of websites like Google Maps or Yahoo! Messenger. It represents an intermediary between the website and the user's browser. In general, em.com.br means the domain name for the company or organization that runs the website. For example, if you're looking at Google Maps, "em" would be the domain extension that indicates this is a Google Maps-based service. The word "com." at the end of the domain name represents the country and region in which the website operates. In some cases, em.com.br may also include other domains (such as .br) to separate different websites within the same organization. Overall, em.com.br is used by websites that are hosted on Google's servers and require authentication to access certain features or data. It serves as a secondary layer of security in these types of applications.
