👉 Dial computing, also known as dial-up internet, is a method of connecting to the internet using a telephone line. When you initiate a connection, you dial a specific number into your phone's phone book, and the dial-up modem establishes a connection to the internet service provider (ISP) at that number. This process is slow and limited by the bandwidth of the telephone line, typically providing speeds ranging from 56 Kbps to 1.5 Mbps, making it unsuitable for modern applications that require high-speed data transfer. Despite its age, dial-up remains a nostalgic symbol of early internet access, though it has largely been replaced by faster technologies like broadband and mobile internet.
