Explanation:
The term black box testing is generally associated with application testing. However, in this
question the term is used for network testing. Black box testing means testing something when
you have no knowledge of the inner workings.
Black-box testing is a method of software testing that examines the functionality of an application
without peering into its internal structures or workings. This method of test can be applied to
virtually every level of software testing: unit, integration, system and acceptance. It typically
comprises most if not all higher level testing, but can also dominate unit testing as well.
Specific knowledge of the application’s code/internal structure and programming knowledge in
general is not required. The tester is aware of what the software is supposed to do but is not
aware of how it does it. For instance, the tester is aware that a particular input returns a certain,
invariable output but is not aware of how the software produces the output in the first place.
