Final answer:
The type of DSL (Digital Subscriber Line) that usually offers the highest bandwidth is b) VDSL (Very High Bitrate DSL).
The answer is option ⇒b
Step-by-step explanation:
VDSL provides significantly higher bandwidth than ADSL (Asymmetric DSL), SDSL (Symmetric DSL), and HDSL (High Bitrate DSL) due to its use of advanced modulation techniques that can transmit data at much higher rates over short distances.
VDSL is capable of supporting applications that require high bandwidth like high-definition video streaming, high-speed Internet access, and digital television services. VDSL is often used in areas where fiber-optic transmission is not available but high-speed data services are desired. However, the bandwidth capability decreases as the distance from the distribution hub increases, which is a typical characteristic of DSL technologies.
The answer is option ⇒b
