Microsoft Security Essentials could be downloaded to replace Windows Defender since it could catch spyware and scan for viruses. Once installed, it would disable Windows Defender altogether.
Operational definition. From Wikipedia, the free encyclopedia. An operational definition is a result of the process of operationalization and is used to define something (e.g. a variable, term, or object) in terms of a process (or set of validation tests) needed to determine its existence, duration, and quantity.he most operational definition is a process for identification of an object by distinguishing it from its background of empirical experience. The binary version produces either the result that the object exists, or that it doesn't, in the experiential field to which it is applied.
The operational definition of an empirical term (i.e., a descriptor of some element of physical experience) is the description of a specific process, or set of validation tests, accessible to more persons than the definer (i.e., said to be publicly accessible), whereby it is (or can be) repeatedly measured or tested.his is especially so in the sciences, where most (if not all) formal definitions (as distinct from arbitrary naming) must be operational definitions or traceable to operational definitions. Operational definitions are particularly important in the physical sciences.
