1. DLS
2. ADLS
3. ASDL
4. ADSL

Answer 1

Correct Answer - Option 4 : ADSL

The correct answer is ADSL.

• Asymmetric Digital Subscriber Line (ADSL) is a technology that allows high-speed video and voice transmission to homes over standard copper telephone lines.

• ADSL is a type of broadband communications technology that transmits digital data at a high bandwidth over existing phone lines to homes and businesses.
• It differs from the less common symmetric digital subscriber line (SDSL). 
• ADSL uses a spectrum that is above the range used for voice calls.
• The majority of ADSL connectivity is currently full-duplex.
• Unlike traditional dial-up copper telephone lines, ADSL enables always-on, always-available broadband connections. ADSL is asymmetric in that it uses the majority of channels to send data downstream to the user and just a small portion to send data back upstream.
