What does an Internet Service Provider do?

An Internet Service Provider (ISP) primarily functions to connect users to the Internet. This connection can be provided through various technologies, such as DSL, cable, fiber-optic, or satellite. The ISP serves as the intermediary between users and the broader Internet, managing data transfer, maintaining network infrastructure, and ensuring that users have access to online resources.

While some ISPs may also offer additional services such as cloud computing, web hosting, or development of web applications, their fundamental role is to provide connectivity. These additional services can vary widely and are not the core function of an ISP. Thus, connecting users to the Internet remains the defining characteristic of what ISPs do.
