A lot of information is in a postal address. You can tell if the sender is a person, a business, or the government. You can tell if the address is a post office box, apartment, or house. You even learn the sender's city, state, and country. This is important information. It helps clue you in to what you are about to open. You may decide not to open it at all! Like postal addresses, web addresses tell you important bits of information. Reading a web address helps you learn about what you are about to open. In the United States, there are five main web address endings. These endings tell you where the information you want to read comes from. For example, ".edu" endings are on web addresses for schools and universities. The government uses the ending ".gov". Businesses use ".com". Non-profit organizations use ".org". Network providers use the ending ".net".
