"Z" is the 26th and final letter of the English alphabet. It is often used to represent the sound /z/, as in words like "zebra" and "buzz." In mathematics, "Z" is commonly used to denote the set of all integers, which includes positive numbers, negative numbers, and zero. In popular culture, "Z" can also refer to various concepts, such as the term "Generation Z," which describes the demographic cohort born roughly between the mid-1990s and early 2010s. Additionally, "Z" is sometimes associated with the Zodiac, which consists of twelve astrological signs.
