56 Kbit/s Modem
A 56k modem is a voiceband modem nominally capable of download speeds up to 56 kbit/s (56,000 bits per second). In the late 1990s, they were the most popular access method for personal Internet usage, but their use has declined in the developed world as broadband internet technologies such as DSL and cable internet, along with mobile data services such as 4G, have been more widely adopted and made available. In other parts of the world, ad hoc wireless networks are being more widely deployed.
