What is the difference between an ISP and a router?

• A. An ISP is a device that routes data.
• B. A router provides Internet connectivity.
• C. ISP stands for Internet Service Protocol.
• D. An ISP provides Internet connectivity to your network; a router distributes that connection to devices.

Answer: (D)

The main idea is understanding who provides the Internet versus who shares it inside your home. An Internet Service Provider is the company that gives you access to the Internet itself—through your cable, fiber, or DSL connection. A router is a local device inside your network that takes that Internet connection and distributes it to your devices, usually by routing traffic and often by creating Wi‑Fi. It also handles sharing one public connection among multiple devices, typically using NAT and private IP addresses. So, the ISP provides the connectivity to the Internet, while the router distributes that connectivity to the devices in your home. Some setups combine these roles in a single gateway, but the essential difference is provider versus local network distribution. The other statements misstate roles: the ISP isn’t just a device that routes data, the router doesn’t itself provide Internet access, and ISP stands for Internet Service Provider, not Protocol.
