Conjugation is nothing but the situation in which one of the saturated bond system has been firmly attached in a direct manner to another unsaturated bond system or basically an atom which are carrying a definite pair of electrons or something in reduced or deficient pair of electrons, where, the final consequence of it will be the localised electrons (formal or common localisation) will be eventually delocalised of that specific part. They can get evenly recognisable from a thermodynamic behavior of matter and Kinetic Behaviour of matter in which the molecules contained in the matter are concerned and given priority, especially in a IUPAC Alkene Compound butadiene in which the two following parts of a conjugated system can be same and will more likely predominate the electronic movements in a single or one direction.

Inductive effects are mostly associated on the basis of an electronic movement via sigma bonds, which widely differs and is actually attributed to change in electronegativity.

If taking resonance effect it's the extension of the Hyperconjugation Effect which involves association with electron movements through \textbf\boxed{"p" Orbitals} and delocalisation of \pi - Electrons of more than two conjugated double bonds or simply \pi - Electrons of a particular double bonding or not exhibiting bonding, this means, suppose n-electrons of a heteroatom, here, the Hyperconjugation will involve delocalisation of presently weak bond called \sigma\textbf{ - Electrons} by this a follow up of \sigma-\pi conjugations making the \sigma\textbf{- orbital} to overlap the \textbf{p - Orbitals} of a single \pi\textbf{-Bond}, hence, it's name has been derived as \textbf{No Bond Resonance}.

In a summarised view, Hyperconjugation effect or also known as \boxed{Baker-Nathan \: Effect} which cannot be described or vindicate the presence of an inductive effect being the only method for explanations for substituents. To make it even more clearer; Hyperconjugation is the inverse of an inductive effect, that is, making the orders reversed and performing a corresponding reaction between Electrons of single \pi\textbf{-Bonds} and an unsaturated system. The term of \textbf{no-bond resonance} was solely being used to describe the type of electronic interactions by bondings, though the contribution of chemical structure is also taken into consideration.

Answer:

In organic chemistry, hyperconjugation (or σ-conjugation) refers to the delocalization of electrons with the participation of bonds of primarily σ-character. ... The Baker–Nathan effect, sometimes used synonymously for hyperconjugation, is a specific application of it to certain chemical reactions or types of structures.
