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.
The systematic and rational allocation method can also be used to amortize intangibles and allocate prepaid costs such as insurance and rent. When both the associating cause and effect and systematic and rational allocation methods cannot be used, expenses are recognized immediately. For example, it can be difficult to identify future benefits of some costs incurred, or for some costs no rational allocation scheme can be devised.
