   * **CShM.** Continuous Shape Measures. A quantitative approach used in coordination chemistry to evaluate the degree of distortion of a molecule's coordination sphere relative to an ideal reference polyhedron (such as a perfect tetrahedron or octahedron). A CShM value of zero indicates a perfect match to the ideal shape. shapeXT provides an integrated tool to calculate and analyze these measures interactively.
   * **COD.** Crystallography Open Database. An open-access collection of crystal structures of organic, inorganic, metal-organic compounds, and minerals. shapeXT allows users to fetch and visualize structures directly from this database using a 7-digit ID.
+  * **CPU.** Central Processing Unit. The primary hardware component responsible for executing general-purpose instructions and logic.
