An Internet Service Provider (ISP) is a company that provides you with access to the Internet, usually for a fee. The most common ways to connect to an ISP are by using a phone line (dial-up) or broadband connection (cable or DSL). Many ISPs provide additional services such as e‑mail accounts, web browsers, and space for you to create a website.
