Zerobase

Zerobase is a term used in multiple contexts and as a proper noun for several unrelated entities. Because it is not tied to a single organization or concept, its meaning depends on the context in which it appears. In general, zerobase can refer to a concept in computing, a budgeting method in finance, or a brand name used by various companies.

In computing, zerobase commonly appears in discussions of zero-based indexing. This convention numbers elements starting at 0, so the first element of an array is at index 0 rather than 1. Zero-based indexing is prevalent in many programming languages, including C, Python, and JavaScript, and it aligns with low-level memory addressing in some contexts. It contrasts with one-based indexing, where counting begins at 1.

In finance and public administration, zerobase is associated with zero-base budgeting. This approach requires each expense to be justified for every new period from a zero base, rather than adjusting previous budgets. The method, popularized in the public sector by Peter Pyhrr in the 1970s, aims to eliminate unnecessary costs and prioritize resource allocation based on current needs and activities.

As a brand name, Zerobase is used by various technology, education, and software firms in different regions. Because it is a relatively generic term, there is no single corporate identity universally linked to the name; trademarks and market presence vary by country and sector.
