Presentation slide

A slide is a single page of a presentation. Collectively, a group of slides may be known as a slide deck. A slide show is an exposition of a series of slides or images in an electronic device or in a projection screen.
Before the advent of the personal computer, a presentation slide could be a 35 mm slide viewed with a slide projector or a transparency viewed with an overhead projector.
In the digital age, a slide most commonly refers to a single page developed using a presentation program such as MS PowerPoint, Apple Keynote, Google Slides, Apache OpenOffice or LibreOffice. It is also possible to create them with a document markup language, for instance with the LaTeX class Beamer.
Lecture notes in slide format are referred to as lecture slides, frequently downloadable by students in .ppt or .pdf format.
Slide producing software.
Presentation slides can be created in many pieces of software such as Microsoft PowerPoint, Apple Keynote, LibreOffice Impress, Prezi, ClearSlide, Powtoon, GoAnimate, Snagit, Camtasia, CamStudio, SlideShare, and Reallusion.
Some software, like competitors PowToon and GoAnimate, produces slides with more animation. Others like CamStudio can be used to record the screen activity.
The most popular pieces of slide producing software are Microsoft PowerPoint, Prezi, Apple Keynote, Google Slides and ClearSlide.
Templates.
Typically in a set of slides (a "deck"), all the slides will have a similar layout template, controlling such factors as margins and headings.

Selection of slide sharing websites.
