Asymmetric Digital Subscriber Line (ADSL) is a technology that allows high-speed internet access over traditional copper telephone lines. It enables users to download data faster than they can upload it, making it ideal for activities like streaming videos and browsing the web. ADSL works by splitting the phone line into separate channels for voice and data, allowing simultaneous use of the internet and telephone. ADSL is commonly used in residential areas where fiber-optic connections may not be available. Its asymmetric nature means that download speeds can be significantly higher than upload speeds, typically ranging from 1 to 24 Mbps for downloads and 64 Kbps to 1 Mbps for uploads, depending on the distance from the service provider's central office.
