How does an ISP work?
An ISP provides access to the Internet through a network infrastructure that consists of routers, switches, servers, and other network equipment. When a user connects to the ISP’s network, the ISP assigns an IP address to the user’s device. This IP address identifies the user’s device on the Internet and allows the user to communicate with other devices and access web content. The ISP also provides DNS services, which translate domain names into IP addresses, allowing users to access websites using easy-to-remember names instead of numerical IP addresses.
