Pairwise (a.k.a. all-pairs) testing is an effective test
case generation technique that is based on the observation
that most faults are caused by interactions of at most two
factors. Pairwise-generated test suites cover all
combinations of two therefore are much smaller than
exhaustive ones yet still very effective in finding defects.
There are also some automated tools to generate pairwise
combinations like TestersDesk.com.
Pairwise testing is the simplest form of combinatorial testing. Another way to state what Arif and Bhagawati have correctly stated is that a primary goal of pair-wise testing is to achieve 100% coverage of potential dual-mode-faults.
More sophisticated combinatorial testing methods can also guarantee 100% coverage of all potential triple-mode-faults, 100% coverage of all potential quadruple-mode-faults, etc.

paurwise testing is a adhoc / monkey testing techniques used
in case of lack of time, lack of documentation, lack of
skills, lack of resources etc.
the lest lead will use this tech due to lack of time . they
will make a tester as a pair with developer. they both cont
testing nd coding parallel.
In pairwise testing, two testers combinly working on the
same system for the same project.
The main aim of pairwise testing is, to exchange of ideas
between the testers.
The sucess of pairwise testing depends on coordination
between the testers.
