A DSL (Digital Subscriber Line) is a technology used to transmit digital data over existing copper telephone lines, providing high-speed internet access without disrupting regular phone service

. It works by using higher frequency bands on the telephone line for data transmission, allowing simultaneous voice and internet use on the same line

. There are several types of DSL, including:

  • ADSL (Asymmetric DSL): Offers faster download speeds than upload speeds, suitable for typical internet activities like browsing and streaming
  • SDSL (Symmetric DSL): Provides equal upload and download speeds, ideal for applications requiring balanced data flow such as video conferencing
  • VDSL (Very-high-bit-rate DSL): Delivers higher speeds for both upload and download, supporting bandwidth-intensive tasks like HD streaming and gaming

DSL internet speeds typically range from a few hundred kbps up to 100 Mbps or more depending on the technology and line conditions

. DSL modems connect to the telephone line and convert digital data for internet use, making DSL a widely available and cost-effective broadband option, especially where fiber or cable infrastructure is limited
