TCP guarantees that no packets are ever dropped is not true about TCP/IP packets.
TCP/IP is a set of communications protocols used to connect hosts on the Internet or a network. Packets are sent from one computer to another over the network. Packets can be lost during transmission, so TCP can’t guarantee that no packets are ever dropped.
Instead, it provides mechanisms to detect and recover from packet loss. It does this by using acknowledgments and retransmission to ensure that all packets are received in order.
The sender also adds a sequence number to each packet so that they can be reassembled in the correct order if they arrive out of order. In addition, packets can be routed on different paths from sender to receiver, which improves reliability and performance.

Which broadband access method implements dmt, odfm, qam, over utp?
Dmt, odfm, qam, and over utp are implemented by the ADSL (Asymmetric Digital Subscriber Line) broadband access technology.
Asymmetric Digital Subscriber Line (ADSL) is a technology that enables high-bandwidth, quick data transfer to homes and businesses over already-existing copper wire telephone lines. In contrast to standard dial-up copper telephone line service, ADSL offers always-on, constantly accessible broadband connections.
There are three primary categories of broadband:
The normal copper cables that transport your phone line are used to bring ADSL straight to your house.
Coaxial and fibre optic cables are used to provide cable.
Fiber, which is supported by bundles of fibre optic cables.
In certain places, especially distant ones, where fibre and cable are still not widely accessible, ADSL may be the sole choice. The ADSL1 and ADSL+ (sometimes known as ADSL2 or ADSL2+) variants of ADSL technology exist. The second iteration, ADSL+, is a little quicker.
