Which statement is true regarding the binary system?

The binary system is a foundational concept in computing and digital electronics that utilizes only two symbols, which are 0 and 1. These two symbols correspond to the off and on states of a digital circuit, respectively. In binary, each digit is referred to as a bit, and its use is essential for representing data in computers and other digital systems.

The nature of the binary system, as indicated by the use of just 0 and 1, makes it particularly suitable for electronic devices, as they can easily distinguish between two states. This simplicity allows computers to perform complex calculations and store data effectively.

In contrast, the other choices describe concepts that are unrelated to the binary system. For example, a base of 8 refers to the octal system, while having ten digits from 0 to 9 pertains to the decimal system, which is base 10. The last option incorrectly suggests that the binary system is mainly used for decimal calculations, whereas it is primarily focused on operations and representations using its two-symbol structure.

Overall, the emphasis on the use of two symbols – 0 and 1 – clearly defines the binary system, making that statement the accurate description of its characteristics.
