**TLDR:** A quantity with direction and magnitude, and one of the most fundamental representations in linear algebra.

<p>A vector is one of the foundational building blocks of linear algebra and is used to represent a data point, a direction, or a set of features. In machine learning, an observation row, a word embedding, or model parameters are often treated as vectors. Vectors are not merely lists of numbers; they also carry geometric and algebraic meaning. Similarity measurement, distance computation, direction analysis, and transformation operations are all built on vectors. For that reason, the concept of a vector is essential for understanding the mathematical language of modern AI.</p>
