strong acid dissociates fully
weak acid dissociates partially

A strong acid dissociates the H+ ion completely. Ie HCl has one H+ ion to give away

HCl --> H+ + Cl-

Compared to sulfuric acid which is weaker. H2SO4 has two H+ ions to dissociate but isn't completely done in one reaction:

H2SO4 - - > H+ + HSO4-
HSO4- <--> 2H+ + SO4-

thank you! sorry my question wasn't phrased very well, i mean how is the neutralisation reaction between a weak acid and a weak base different to a reaction between a strong acid and a strong base

Look at the titration curves in your work book. The equivalence points are different depending if it's a strong acid vs. strong base or strong acid vs weak base
