A "Carrier" is a person or company that transports goods or people from one place to another. In the shipping industry, carriers can be trucks, ships, or airplanes that move products across cities, countries, or even continents. They play a crucial role in global trade by ensuring that items reach their destinations safely and on time. In the context of telecommunications, a carrier refers to a company that provides services for transmitting data, voice, or video over networks. Examples of such carriers include Verizon, AT&T, and T-Mobile. These companies enable communication by connecting people through their mobile phones and internet services.
