Iceberg

An iceberg is a natural phenomenon where a large chunk of ice breaks off from a glacier or ice shelf and floats in the ocean, with a significant portion remaining submerged beneath the surface. In tech discussions, the term "iceberg" is often used metaphorically to describe complex issues or problems where the visible symptoms are only a small part of a much larger, underlying problem, making it a relevant concept for developers and problem-solvers to understand and address.
