In a binary quantity, what is assigned a specific weight based on its position?

In a binary quantity, a bit is fundamental because it represents the smallest unit of data in computing and digital communications. Each bit can be in one of two states: 0 or 1. However, the critical aspect of a bit is how its significance changes based on its position in a binary number. The position of each bit determines its weight in the overall value of the number.

For example, in the binary number 1011, the weights from right to left correspond to 2^0, 2^1, 2^2, and 2^3, or 1, 2, 4, and 8, respectively. Therefore, each bit contributes to the final value based on its position – the leftmost bit holds the greatest value while the rightmost holds the least.

The other choices do not accurately reflect the concept of weight based on position in the same way a bit does. A byte consists of 8 bits, representing a larger unit of data but doesn’t address weight on its own. Decimal refers to a number system based on ten digits and doesn’t pertain directly to binary positional significance. A signal generally implies a form of electronic transmission rather than the positional value of binary digits.

Thus,
