Final answer:
Typically, binary message sending devices use two states due to their simplicity, reduced error susceptibility, and alignment with computer operations. More states could increase complexity and potential for errors. Binary systems offer a balance between efficiency and reliability in digital communication.
Step-by-step explanation:
In a binary message sending device, messages are sent as sequences of two states – typically represented as State A (0) and State B (1). This design choice is rooted in the principles of digital communication and binary encoding. Binary systems are simpler to build and less susceptible to errors compared to systems with multiple states. In a binary system, each binary digit (bit) can only have one of two values, which translates into a straightforward physical representation, such as on or off, high or low voltage, or presence or absence of a signal.
Using just two states also benefits error detection and correction. With fewer states, it is easier for electronic circuits to distinguish between them, reducing the chance of misinterpreting the signal due to noise or interference. Moreover, the use of binary encoding aligns well with the fundamental operation of computers, as they are inherently designed to process binary information.
While having more states (like State C, D, E, etc.) could theoretically increase the amount of information sent per signal, it would also increase the complexity of the device and the potential for errors. More states mean the signal variations are closer together, making them more difficult to distinguish from one another, especially in the presence of noise. Therefore, the elegance, reliability, and ease of implementation make binary systems the preferred choice in digital communication.
