An Internet Provider, also known as an Internet Service Provider (ISP), is a company that offers access to the Internet for individuals and businesses. ISPs connect users to the web through various technologies, such as fiber optics, cable, or DSL. They may also provide additional services like email accounts and web hosting. ISPs can be categorized into different types, including dial-up, broadband, and satellite providers. The choice of an ISP often depends on factors like speed, reliability, and cost. Users typically subscribe to a plan that suits their needs, allowing them to browse websites, stream videos, and communicate online.
