101000xyz

101000xyz is a string that commonly appears as a placeholder or sample identifier in computing, data science, and technical documentation. It does not refer to a single, widely recognized object; instead, the sequence is used across contexts to illustrate labels, keys, or values.

The prefix 101000 resembles a binary-looking segment, while the trailing letters xyz serve as a conventional suffix. The combination is convenient because it mixes numeric and alphabetic characters in a compact, easy-to-remember form.

In educational materials, 101000xyz is used to demonstrate string handling, parsing, and pattern matching in regular expressions. In example databases or seed data, it can function as a temporary primary key or a unique identifier that is unlikely to collide with real records.

Variations such as 101000abc or 101001xyz are also encountered in similar contexts. The exact meaning of the string depends on the domain, and in professional settings it is typically defined in accompanying documentation rather than treated as a universal standard.
