Which of the following is known for providing fast internet via copper wires?

• A. ISDN
• B. FTTP
• C. DSL
• D. Dedicated line

Answer: (C)

The option that provides fast internet via copper wires is DSL, which stands for Digital Subscriber Line. DSL technology uses existing copper telephone lines to transmit digital data, allowing users to access the internet at higher speeds than traditional dial-up connections. It enables simultaneous use of the internet and phone services without interference, making it a popular choice for residential and small business internet connections. DSL achieves its speed by utilizing a wider frequency band than is used for voice calls, allowing for greater data transmission. This method of leveraging existing infrastructure is both cost-effective and widely available in many regions where other high-speed internet options may be limited. In contrast, ISDN (Integrated Services Digital Network) primarily provides a digital connection for voice and data, but typically at lower speeds than DSL. FTTP (Fiber to the Premises) uses fiber-optic cables, which offer much faster internet speeds but don't utilize copper wiring. A dedicated line refers to a permanent connection, but it can be established through various technologies and does not specifically denote the use of copper wires like DSL does.
