系统

维基百科里是这样定义系统(System)的:

System (from Latin systēma, in turn from Greek σύστημα systēma) is a set of entities, real or abstract, comprising a whole where each component interacts with or is related to at least one other component and they all serve a common objective. Any object which has no relation with any other element of the system is not part of that system but rather of the system environment. A subsystem then is a set of elements, which is a system itself, and a part of the whole system.

翻成中文大体意思就是: 系统,是一系列的真实的或者抽象的对象,以及对象之间的交互影响构成的。
