what is dsl internet service

DSL stands for Digital Subscriber Line, which is a type of internet connection that uses existing telephone lines to transmit data. DSL technology uses separate frequencies for phone and internet, so you can use both at the same time. DSL is a cost-effective method to connect to the internet with high-speed bandwidth, as compared to cellular data. DSL speeds vary from 256 Kbps to 100 Mbps, depending on the package offered by the internet service provider. DSL is a good option for rural areas where cable and fiber internet infrastructure is not available. There are two types of DSL transmission: Asymmetrical Digital Subscriber Line (ADSL) and Symmetrical Digital Subscriber Line (SDSL). ADSL is primarily a residential option for families who surf the internet and may receive a lot of data without sending out very much, while SDSL is more of a business service for subscribers who need video conferencing and significant bandwidth for both upstream and downstream data. DSL is slowly losing its popularity due to the global penetration of mobile devices and cellular networks, but it remains relevant in towns and regions with established providers.
