Slides

Slides are a collection of pages or images presented in sequence to communicate information. In modern contexts, the term most often refers to slide decks used in lectures, meetings, and conferences. A slide typically contains text, images, charts, or other media arranged to convey a clear point or idea.

Digital slide decks are created with software such as PowerPoint, Google Slides, or Keynote. They may include speaker notes, templates, and embedded media. Slides are shared online or offline, edited collaboratively, and projected onto screens for live presentation. The sequence is usually linear, though presenters can navigate nonlinearly using hyperlinks or sections.

Photographic slides, also known as transparencies, are small transparent images mounted in a frame for projection with a slide projector. They were widely used in education and cinema before digital projection became dominant.

A microscope slide is a thin piece of glass or plastic on which a specimen is placed for examination under a microscope. Prepared slides may be stained to highlight structures. The term slide is also used in various laboratory procedures and terminology, referring to the surface or the action of placing a specimen for viewing.
