Which of the following best describes a Digital Subscriber Line?

A Digital Subscriber Line (DSL) is characterized as a form of broadband internet service. This technology uses existing telephone lines to deliver high-speed internet access to users. Unlike older dial-up services, which are significantly slower and can interrupt phone services, DSL allows simultaneous use of the internet and telephone without interference, providing a more efficient and faster connection.

Broadband internet refers to high-speed internet connections that provide significantly faster speeds than traditional dial-up connections. DSL represents one of several methods to achieve broadband connectivity, alongside other technologies like cable and fiber optics. This distinction is crucial as it highlights the nature of DSL as a modern approach catering to the growing demand for higher data transfer speeds in both residential and commercial environments.

The other options do not accurately define DSL. A wireless internet connection indicates a lack of physical cabling, which is not true for DSL, as it relies on wired connections through telephone lines. Dial-up internet service is outdated and operates at much slower speeds, while local area network (LAN) technology pertains to network connections within a limited geographic area, such as homes or offices, which is separate from the definition of DSL.
