DSL vs. ADSL: Know the Difference
By Shumaila Saeed || Published on January 3, 2024
DSL (Digital Subscriber Line) is a broad category of broadband internet access, while ADSL (Asymmetric Digital Subscriber Line) is a specific type of DSL with different upload and download speeds.
Key Differences
DSL is a general term for technologies that provide digital data transmission over telephone lines. ADSL, a subtype of DSL, specifically offers higher download speeds than upload speeds, making it asymmetric.
