What is the primary function of an Internet Service Provider (ISP)?

The primary function of an Internet Service Provider (ISP) is to enable internet connectivity for customers, which includes both individual users and businesses. ISPs facilitate access to the internet by providing the necessary infrastructure, such as high-speed broadband connections through various technologies including fiber-optic, DSL, cable, and satellite. They also maintain the routing and switching necessary to connect users to the broader internet, allowing for the transmission of data packets between devices and servers across the globe.

In addition to providing connectivity, ISPs may also offer additional services like web hosting and email, but their core purpose revolves around ensuring that users can connect to the internet. This foundational role is critical for not only personal use but also for the functioning of businesses, educational institutions, and other organizations that rely on consistent and reliable internet access to operate effectively.
