Which statement best defines an Internet Service Provider (ISP)?

• A. A device that forwards packets between routers
• B. A system that translates domain names to IP addresses
• C. A service that hosts websites
• D. A company that provides an internet connection

Answer: (D)

An ISP is the company that provides your access to the Internet. It owns and operates the networks that connect your home or device to the broader online world, handling the transmission of data between you and other networks. The other descriptions point to specific parts of the Internet infrastructure or related services—like a router that forwards packets between routers, DNS that translates domain names to IP addresses, or web hosting that stores and serves websites. Those are important pieces, but they aren’t the provider of your overall Internet connection. So the best definition is the company that supplies the connection to the Internet.
