ADSL, or Asymmetric Digital Subscriber Line, is a type of Internet connection that uses telephone lines to deliver high-speed Internet. It is called "asymmetric" because it provides faster download speeds than upload speeds, which is ideal for activities like streaming or browsing. ADSL allows users to use the Internet and make phone calls at the same time, without the need for separate lines. It is widely used in areas where fiber-optic or cable connections are not available, offering a good balance of speed and accessibility over existing telephone infrastructure.
