  In $\nu/\bar{\nu}$-N/A interactions SIS is technically defined in terms of
the four-momentum transfer to the hadronic system as non-resonant meson
production with $Q^2 \lessapprox 1~GeV^2$. This non-resonant meson production
intermixes with resonant meson production in a regime of similar effective
hadronic mass W of the interaction. As $Q^2$ grows and surpasses this $\approx
1~GeV^2$ limit, non-resonant interactions begin to take place with quarks
within the nucleon indicating the start of DIS region. SIS and DIS regions have
received varying degrees of attention from the community. While the theoretical
/ phenomenological study of $\nu$-nucleon and $\nu$-nucleus DIS scattering is
advanced, such studies of a large portion of the SIS region, particularly the
SIS to DIS transition region, have hardly begun. Experimentally, the SIS and
the DIS regions for $\nu$-nucleon scattering have minimal results and only in
the experimental study of the $\nu$-nucleus DIS region are there significant
results for some nuclei. Since current and future neutrino oscillation
experiments have contributions from both higher W SIS and DIS kinematic regions
and these regions are in need of both considerable theoretical and experimental
study, this review will concentrate on these SIS to DIS transition and DIS
kinematic regions surveying our knowledge and the current challenges.
