This document discusses the history and development of internet connection speeds. It describes how people initially connected to the internet via slow dial-up connections of 56kbps. Over time, faster connections such as ISDN and ADSL were introduced, offering speeds up to 512kbps. Once connections reached 1Mbps (megabits per second), they were widely referred to as broadband. Modern internet connections now typically offer speeds of 8Mbps or higher.
