To connect to the internet, users must cross the "last mile" using an internet service provider (ISP). When choosing an ISP, it's best to research options using a search engine and review sites. Important factors to consider include connection speed, price, data limits, trial periods, and customer support. Once signed up, use speed test sites to verify the actual connection speed. Download times for a given file size can be calculated based on connection speed in bits per second. Faster speeds are more expensive but allow for quicker downloads and smoother online experiences. Common connection types include DSL, cable, satellite, and fiber optic networks.
