What is a single entry within a list called?

A single entry within a list is referred to as an element. In the context of data structures, a list is a way of organizing and storing multiple values. Each value within that list is an individual element. Elements can hold various types of data, such as numbers, strings, or even other data structures, depending on the programming language used.

The term "node" typically refers to elements in more complex data structures, like linked lists or trees, where each node can contain additional information beyond just the value (such as pointers to other nodes). A "value" is a broader term that refers to any piece of data, but does not specifically denote its position or context as an entry in a structured list. A "record" often refers to a more complex structure that can contain multiple fields (like a database entry), and is not limited to being a single entry in a list.

Thus, the term element is precise and accurately describes an individual entry in a list.
