Key Characteristics
An Internet Service Provider (ISP) is a company that provides internet access to individuals and organizations, serving as the gateway between users and the global internet infrastructure. ISPs operate networks of servers, routers, and other equipment that connect customers to the broader internet. They provide various types of internet connections including DSL, cable, fiber optic, satellite, and mobile data.
ISPs also offer additional services such as email hosting, domain registration, web hosting, and VPN services. They participate in the global routing system by exchanging traffic with other ISPs through peering agreements and transit arrangements. ISPs play a critical role in internet governance and security.
