Final answer:
The statement is true as a string in programming refers to a sequence of characters used as data. Digital data, including cell phone conversations and video images, are also transmitted as sequences of binary ones and zeros to improve communication efficacy.
Step-by-step explanation:
The statement that a sequence of characters that is used as data is called a string in programming is True. In programming, a string is essentially a sequence of characters that are used to represent text. Each character in the string is typically encoded using a standardized character encoding such as ASCII or Unicode, which then can be stored and transmitted as digital data.
Similarly, digital data like cell phone conversations, television voice and video images are also converted into a sequence of binary ones and zeros for transmission. This binary representation, where each binary digit (bit) can be either a 1 or a 0, is crucial for various forms of electronic communication. It allows not only for the clear transmission of data when signals are weak but also facilitates the compression of data, making it possible to transmit more information within the same frequency range.
