OVER HEAD PROJECTER
It consists of a base area with a transparent glass covering onto which light is focused from below. A projector lies above this base i.e. "over the head", which magnifies the light coming from below and projects it onto the desired point. This device is quite indispensible whenever one thinks of a presentation to be given in a class. They are a modified version of the slide projector used in 50's and 60's period which could present a limited number of photographic images. These OHP's as we call them are much better than their ancestors as a number of transparencies can be made and displayed. It is both time-saving and easy to cover up a lot of topics in a quick manner.
DIGITAL PROJECTERS

These are the latest in the line which come with a HDMI port that can be used to connect the laptop or computer with them and display on a screen the slides that are available. They have a wider audience reach as compared to others. Also audio and video files can be played with their help. Generally they are hoisted on the ceiling of a room and are thus confused with an Over Head Projector due to the name which it implies.
LAPTOPS / COMPUTERS
They have revolutionized the way things are done in any field including the field of education. They are vital for making presentations, for learning computer programming languages and combined with the internet knowledge is right in front
POWERPOINT SLIDES
It has definitely become a trend these days to come with a power point presentation for various tasks. Starting from games to educational content there seems to be no dearth to the things which this app can do. It is a very easy to make and use and students are definitely pulled towards thse flashy slides.
