projector is an output device: a device that projects an image or display onto a surface. It has some similarities to a monitor in that it also displays content but differs by being remotely connected to other input devices, such as mouse and keyboard or stylus pen and touchscreen.

The one that most projectors use is a DC power adapter. The other two being battery and plug-in power. A DC power adapter, like the one in this picture, is commonly used on projection screens because it can be simply plugged into a wall socket and the projector works off that power supply.

 Many projectors come with this type of power supply as standard and it is considered very safe to use as they are designed specifically for low voltage electronics like speakers, amplifiers or lighting control systems. Another way to use a projector is by using battery power. This is also referred to as portable or rechargeable battery supply (RCA). Introduction

The word “projector” has roots in Latin, meaning to throw or cast. In the early 1700s, a French physicist named René Antoine Ferchault de Réaumur was experimenting with images that could be projected by candlelight onto a wall or surface.

The different lengths of light waves would create patterns on the wall depending on the distance between light and the surface where it was projected.

De Réaumur called this process “shadowgraphy”—a phrase that later became shortened to “shadowgraphs” and eventually just “shadowgraphs.

Projector can be defined as an output device which projects images created by the computer onto an external viewing surface, such as a wall or screen.

Tablets:

If you are looking to make a budget friendly presentation, a tablet would be your best option. Tablets have great apps that allow the user to create and edit their presentations on the go and store them on their device. This is convenient in cases where you aren't able to bring your computer or don't have a means of accessing the internet.
