For example, while connecting to the Internet, the connection between the Internet-enabled device and the internet is executed through a specific transmission technology through an Internet Protocol route that involves the transfer of information packets. Data is transmitted through different technologies, including cable modem, DSL, dial-up, high speed interconnects. Accordingly, based on the method of data transmission, the Internet access provided by ISPs can be divided into many types, some of which are; Dial-up Internet access, DSL, Wireless Broadband, Wi-Fi Internet, ISDN, and Ethernet.

Dial-up Internet access is the oldest technology by modem to modem connection using telephone lines to provide Internet access. In this method, the user’s computer is connected to a modem with a telephone line. Due to slow connection speed, this method has become outdated and new methods like Wireless Broadband, Wi-Fi Internet, ISDN, and Ethernet have come into existence.
