Framing of this paper is to project the recent research work on K–T1/2 spaces where K= α, p,β,s & pr and to overview their fundamental properties at a glance. However, the structure and characteristics possessed by these spaces are not always that easy to comprehend. These spaces are very useful in the study of certain objects in digital topology viz E.D. Khalinmsky et.al  showed that the digital line is a typical example of a T1/2-space in which the closed sets and g-closed sets coincide.
