Описание тега black-box
A black box is a device, system or object which can be viewed in terms of its input, output and transfer characteristics without any knowledge of its internal workings.
- In computer programming and software engineering, black box testing is used to check that the output of a program is as expected, given certain inputs.[4] The term "black box" is used because the actual program being executed is not examined.
- In computing in general, a black box program is one where the user cannot see its inner workings (perhaps because it is a closed source program) or one which has no side effects and the function of which need not be examined, a routine suitable for re-use.
- Also in computing, a black box refers to a piece of equipment provided by a vendor, for the purpose of using that vendor's product. It is often the case that the vendor maintains and supports this equipment, and the company receiving the black box typically are hands-off.
