ADSL is called "asymmetric" because it offers higher download speeds than upload speeds, which aligns well with typical internet usage patterns where users often download more data than they upload.

• Asymmetric Speeds: ADSL provides higher download speeds compared to upload speeds, catering to typical internet usage where downloading data (like web browsing and streaming videos) is more frequent than uploading.

• Uses Existing Telephone Lines: It utilizes existing copper telephone lines for internet connectivity, allowing for broadband internet access without the need for new infrastructure.

• Simultaneous Voice and Data Transmission: ADSL technology separates voice and data transmission, enabling users to access the internet and use the telephone simultaneously over the same line.

ADSL played a significant role in the widespread adoption of broadband internet in the late 1990s and early 2000s, offering a major speed improvement over dial-up internet connections.
