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.

What is programming language?A computer language used by programmers (developers) to communicate with computers is called a programming language. It is a set of instructions written in any language, including C, C++, Java, and Python, to carry out a particular action.
Assembly language (ASM) is another type of low-level programming language that is made for specific processors. High-level programming language (HLL) is made for making software programs and websites that are easy to use. Low-level programming language is machine-dependent (0s and 1s) programming language. To convert the program into machine language (execute the program), this programming language requires a compiler or interpreter.
Execution in C/C++
The final stage of building a C++ program is execution. The object file is transformed into an executable file with the extension.exe at this point. The program has its own existence once it becomes an executable file. This implies, you can run your application without the assistance of any compiler or IDE.
Therefore, constant x = 5 is the constant variable can potentially be modified during the execution.
