Slide transition means to change the effect of appearance of slide on screen as well as disappearance of slide from the screen. In slide transition, special effects are added to the slides that make the presentation more attractive and beautiful. The slides appear and disappear in a very beautiful way from right or left or in or down or slides dissolve gradually etc. It develops an interest in the viewers to see your presentation. If transitions are not applied to the slides then new slide simply appears in place of the previous one. This way of presentation without transition may loose the interest of people and you can not convey your ideas to others with good impression. Most of the design templates have added transition effects; it is because these are more attractive. 

In PowerPoint, there are two types of transitions.
