Any substance consisting of two or more different types of atoms (chemical elements) in a fixed proportion of its atoms (i.e., stoichiometry) can be termed a chemical compound; the concept is most readily understood when considering pure chemical substances.
Definition - What does Over-Allocation mean? Over-allocation generally refers to situations where resources are allocated at excessive levels. In the context of IT, the resources often refer to hardware or software capabilities such as processing power, memory, data management, bandwidth or other specifications.
Cost Allocation Methods The very term allocation implies that there is no overly precise method available for charging a cost to a cost object, so the allocating entity is using an approximate method for doing so. Thus, you may continue to refine the basis upon which you allocate costs, using such allocation bases as square footage, headcount, cost of assets employed, or (as in the example) electricity usage.
