An unsigned 1-byte data type can represent which range of integers?

Explanation:
An unsigned 1-byte data type uses 8 bits to store non‑negative integers. With 8 bits you can represent 2^8 = 256 distinct values, starting at 0, so the range is 0 to 255. It can’t represent negative numbers because there’s no sign bit. This differs from a signed 8-bit type (which would be -128 to 127) or a 16‑bit unsigned type (0 to 65535). The range 1 to 100 doesn’t reflect the full 0 to 255 span.
