Which DSL technology offers speeds of up to 50 Mbps for downloads?

• A. Asymmetric DSL (ADSL)
• B. Very High Bit-Rate DSL (VDSL)
• C. Digital Subscriber Line (DSL)
• D. Symmetric DSL (SDSL)

Answer: (B)

Very High Bit-Rate DSL (VDSL) is a DSL technology that provides significantly higher speeds compared to traditional DSL methods. It can achieve download speeds of up to 50 Mbps or even higher, depending on the distance from the service provider's central office and the quality of the copper lines used. VDSL achieves its high speeds by utilizing a higher frequency range than its predecessors, allowing for more data to be transmitted simultaneously. This makes it a suitable choice for applications that require greater bandwidth, such as streaming high-definition videos or online gaming. In contrast, Asymmetric DSL (ADSL) typically offers lower download speeds, usually up to about 24 Mbps, and is more optimized for download-heavy scenarios where users download much more data than they upload. Symmetric DSL (SDSL) provides equal upload and download speeds but generally offers lower maximum speeds compared to VDSL. The term DSL refers to the general technology used for all these types but does not specify speed or performance characteristics like VDSL does. Thus, VDSL stands out specifically for its high download speeds of up to 50 Mbps, making it the correct choice.
