Glossary
Our glossary is your guide to exploring presentation terms and
definitions.
Action Buttons
These are the already present buttons in PowerPoint, these buttons are used to navigate between slides and, also, as a trigger to play the multimedia files. The buttons are available in numerous shapes and, could be used easily to solve your purpose.
Agile Designing
It is an approach to project management and design management used for increasing efficiency and output. Multiple iterations are carried out to come up with the best design in record time.
Ambient Light
It is the natural light, which is already present in the room. Abient light is well known to improve photography as natural light is more suitable for this purpose. Many artificial lights also behave as the ambient light as its output is similar to the natural ones.
Animation
It is used to show the visual effect within the presentation to keep the audience engaged and show live communication media. Several images are merged and used in continuance to perform an animation.
Aliasing
It is the visual stair-stepping of edges that happens in an image when the resolution is too low. Then anti-aliasing is deployed for smoothing of jagged edges in digital images by maintaining the colours of the pixels at boundaries.
Aspect Ratio
It is the ratio of length and breadth either of a screen or media. This aspect ratio defines the display on screens as every screen demands a specific aspect ratio. The most common aspect ratio is 16:9 used by computer screens.
Backlit
It is a type of light used to present pictures in Liquid Crystal Display. LCDs do not produce their own photons so it requires backlit to display the image on the screen.
Bandwidth
Bandwidth is the maximum rate of data transfer over the medium. It is largely defined by the frequency, and bandwidth varies according to the same. It may also be called as the capacity of a device to transfer the amount of data.
Bit Mapped Graphics
It is a 2D array of pixels. The total amount of pixels in a picture is known as the resolution, and the amount of colours that can be used is defined by the bit depth.
Black Slide
PowerPoint lets you present a black slide any time, during the course of your presentation. If someone asks a question that’s irrelevant to the slide displayed, then you may answer the question without distracting the audience.
Blank Slide
This slide could be used to portray the new aspect of your presentation. It could be posted anywhere in the slideshow and lets you add media to showcase the information.
Caption
The caption is the information about the photograph, video or any other media used. You may also use the caption for a slide to give some information about its contents.
Citation
When a presenter wants to provide references or give credits to the person or medium from which it has been taken, citations are used. It is important as you can’t use the information as your own.
Clip Art
Clip arts are the already made images, used to represent a medium. Clip art comes in many forms, both electronic and printed. Though most clip art today is designed, and used in digital form.
Collaborative Designing
It involves many different minds and they come up with intuitive ideas. This is achieved after brainstorming by multiple people. Collaborative designing helps organizations in coming up with creative designs.
Colour Temperature
This is the unit to measure absolute temperatures. There are cool colours, lower cool colours, and warm colours represented differently. It is generally represented in degrees or Kelvin.
Colour Resolution
It is also known as the depth of colour. It is the ability of the pixel to represent different colour tones. Colour resolution is measured on the parameters of RGB (Red, Green, Blue) colour representation.
Crop
Images are usually trimmed to show the precise part of the image. There are numerous cropping tools available, which also help in reducing the image size.
Compatibility
Multiple devices and software interact with each other in multiple environments. For smooth functioning, they must be following similar rules of operation and remain compatible.
Contrast Ratio
This is the ratio between two colours, the brightest colour of the image and the darkest colour of the image. High contrast ratio means more range of colour display by any device.
Dimension
These are the coordinates on different axes. The dimensions could be in the form of length, breadth, height, and depth. It largely defines the size of a document.
Design
Design is the aesthetic display of any product. Designs could be in any form and are dynamic for every product available for our use. Designs make a product look attractive to users.
Dot Pitch
It measures the distance between two dots or pixels to define the sharpness of a display. It could also be specified for printer, image scanner and other pixel-based devices.
Display
It is an output device used to showcase information in the visual format. The display technology has come a long way, making them crispier and more detail-oriented.
Distribute
Delivering the presentation is one aspect, and sharing the same with the masses is another. Distribution of presentation lets you give the information to a lot more people.
Divide
Presentation is well divided, or partitions are made to accommodate useful information and also to display the contents in a visually appealing way.
Draw
It is the way of scribbling creativity to offer a raw outlook to the presentation. The audience is attracted to hand-drawn images as they find it a bit different from electronically prepared photographs.
Front Room Projector
The front room projectors are used for domestic purposes. These projectors are kept in the living rooms(mostly) to let the family enjoy the images and videos on the bigger screen.
Flat Screen
It’s an output device used to display multimedia. This output device has a flat-screen if compared with the round screens used in old times.
Focal Length
The focal length is a measure of convergence and divergence of light. A positive focal length depicts that a system converges light, but a negative focal length depicts that the system diverges light.
Ghosting
It is a technique of creating a rough draft of the proposal or any other official document. This helps in coming up with an outline, which could be converted into a final presentation.
Genlock
Genlock or generator locking is a technique used for the purpose of video synchronization; in this technique, the video is synchronized with other pictures so that it looks like a movie

Google Slides
It is a cloud-based platform often referred to as the SaaS platform used for creating presentation decks and sharing them. The storage is always available on the cloud.
High Gain Screen
Gain is a measurement of the reflectivity of any screen or projection surface. A high gain screen suggests higher reflection and more clarity of an image displayed on the screen.
Horizontal Synchronization
HSYNC is a signal given to the monitor telling it to stop drawing the current horizontal line, and start drawing the next line. The amount of time this takes to occur is measured in Hz (Hertz), which is a measure of cycles per second
HDTV
It is a high definition video format used by broadcasters to record and share the videos in high definition. The images are crisp and clear compared to the standard formats.
Horizontal Frequency
Horizontal frequency is the number of single lines of pixels that are changed per second. This frequency lets us know about the quality of the display.
Horizontal Resolution
The number of elements, dots or columns from left to right on a printed page, display screen or fixed area such as one inch. This tells us about the resolution of the page.
Hz
Since frequency is measured in cycles per second, one hertz equals one cycle per second. Hertz is used commonly used to measure wave frequencies, such as sound waves, light waves, and radio waves.Â
Invert Image
An image in which up and down, as well as left and right, are interchanged; that is, an image that results from rotating the object 180° about a line from the object to the observer.
Icons
It is a representation of emotions and ideas in a graphical format. These are like small clip arts which are usually made using vector graphics.
Interlacing
With an interlaced display the picture is created by scanning every other line, and on the next scan, scanning every opposite line. Interlacing allows for a faster refresh rate by having less information.
JPEG
JPEG or Joint Photographic Experts Group is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography.
KEY
It is a file extension of the presentations made with Apple Keynote. The KEY files created by this software are similar to PowerPoint files, but they are for Mac users and are not functional on Windows computers
Keynote
Keynote is a presentation software application developed as a part of the iWork productivity suite by Apple Inc. It is similar to Microsoft’s PowerPoint but only works in the Mac environment.
LCD
LCD or liquid crystal display is a flat-panel display or other electronically modulated optical devices that uses the light-modulating properties of liquid crystals combined with polarizers.
Long Throw Lens
Providing very large images, this type of throw is usually from projectors that are installed in the center of the ceiling in a large room.
Lock Object
This function is used to lock shapes by selecting an object and clicking on the Lock Shapes option. This will let you lock it and move ahead with other objects.
Metal Halide Lamp
A metal-halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides. It is a type of high-intensity discharge gas discharge lamp.
Multimedia Presentations
AÂ multimedia presentation is a presentation that includes information presented with slides, video, or digital representations and includes sound which might be a narrative, music or sound effects.
Multiplexing
Multiplexing is a method by which multiple analog or digital signals are combined into one signal over a shared medium. The aim is to share a resource with many people.Â
NTSC
NTSC or National Television System Committee is the analog television colour system that was introduced in North America in 1954 and stayed in use until digital conversion.
Network
A network is a group of systems that use a set of common communication rules over digital interconnections for the purpose of sharing resources. Networks could be wired or the signals could be transmitted over satellite.
Output
An output device is any piece of computer hardware equipment, which converts information into a human-readable form. Output devices convey the information in multiple formats.
Overlay
It is a technique used to enhance the quality of the image through editing. Images are made to look beautiful and pop up using the overlay features.
Overhead projector
It is like a film or slide projector that uses light to project an enlarged image on a screen. In the overhead projector, the source of the image is a page-sized sheet of transparent plastic film with the image to be projected.
PPTX
PPTX is a zipped, XML-based file format that is part of the Microsoft Office Open XML specification, introduced as part of Microsoft Office 2007 and later. PPTX is the default presentation file format for new PowerPoint presentations.
PAL
The . pal file extension is most commonly associated with colour palette files used by a variety of software applications. The PAL files contain a palette of colours used by the programs.Â
Pixel
In digital imaging, a pixel, or picture element is a physical point in a raster image or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element of a picture represented on the screen.
Presentation Ergonomics
It is a way to work smarter, not harder by designing tools, equipment, work stations and tasks to fit the job to the presenter and not the presenter to the job.
Presentation
A presentation is a means of communication that can be adapted to various speaking situations, such as talking to a group, addressing a meeting or briefing a team.
PowerPoint
PowerPoint is a presentation program. It was released on April 20, 1987, initially for Macintosh computers only. Microsoft acquired PowerPoint for $14 million three months after it appeared.
RGB
The RGB colour model is an additive colour model in which red, green, and blue light are added together in various ways to reproduce a broad array of colours.Â
Resolution
The resolution is the width and height dimension of an electronic visual display device, such as a computer monitor, in pixels. Certain combinations of width and height are standardized and typically given a name and an initialism that is descriptive of its dimensions.
Render
Rendering is the process of generating an image from a model, by means of a software program. It would contain geometry, viewpoint, texture lighting information.
Simulated Colour
Simulated Colour is used to reproduce almost any image on the market. It does so by overlapping and blending colours and producing them on the desired object.
Section Divider
Section dividers change the entire look and feel of any website. These are used to divide the parts of the webpage so that it looks less cluttered and is easy to navigate.
Slideshow
Slideshows are digital photo galleries or the presentation slides, where any number of photos, graphics, slides are strung together in a presentation.Â
Slides
A slide is a single page of a presentation. Collectively, a group of slides may be known as a slide deck. When these are presented in sync it becomes a slideshow.
SVGA
SVGA or Super Video Graphics Array is a set of video standards one step above VGA. SVGA monitors are capable of displaying up to 16 million colours with a resolution of 800 x 600 on 14-inch monitors and up to a 1200 x 1600 resolution on a 20-inch one.
TFT
Thin Film Transistor (TFT) is a type of LCD flat-panel display screen. It’s called so because each pixel is controlled by transistors. TFT is now replaced with LEDs in the market.
Transitions
It is the technique while presenting to move from one object to another. This technique is deployed to portray ideas of multiple dimensions. For toggling between multiple slides transitions are used.
Title Slide
This one is the first slide of a presentation where the title or the agenda of the meeting is displayed. Usually, this slide doesn’t have much information, it just tells you, what to expect next.
Texture
The texture is a characteristic component of graphic design that uplifts the presence of other visual elements like patterns, colours, illustrations, content, and more.
Ungroup
If you have multiple objects grouped together, you always have the option to ungroup those elements and use them separately. This is mainly required while animating the presentation.
Vertical Resolution
The number of rows, dots or lines from top to bottom on a printed page, display screen or fixed area such as one inch. Contrast with “horizontal resolution,” which is the number of elements, dots or columns from left to right.
VGA
VGA or Video Graphics Array is a standard connector used for computer video output. The 15-pin connector is used widely in PCs, as well as many monitors, projectors and high definition television sets.
Video
When numerous pictures are combined together to form a frame and they are associated to show a moving impression, video is obtained. This is a widely used multimedia format used to show information, which becomes easier to perceive.Â
Video Compatibility
Videos are available in numerous formats like MP4, AVI, MPEG4 and many others. These formats follow different rules and the rules must be similar to the medium you are using to play the video. If there is dissimilarity, your video won’t be compatible with your device.
Whiteboard
Generally, it is recommended to use a whiteboard for the purpose of projection from a lens. When an image is projected, if it falls on a whiteboard you tend to receive maximum clarity. The same amount of clarity is not possible with any other colour.
XGA
XGA or Extended Graphics Array is a high-resolution video display mode that provides screen pixel resolution of 1,024 by 768 in 256 colours or 640 by 480 in high (16-bit) colour.Â
Y/C Connector
The S-video cable carries video using two synchronized signals and ground pairs, termed Y and C. Y is the luma signal, which carries the luminance or black-and-white of the picture, including synchronization pulses. C is the chroma signal, which carries the chrominance of the picture.
Y Cable
A Y-cable, Y cable or splitter cable is a cable with three ends; one common end, and two other ends. It could be used for single input and multiple outputs scenarios. The Y-cable can resemble the Latin letter “Y”
Zoom
When referring to an image or graphic, zoom describes the function of focusing on a section of an image and increasing its overall size for greater detail.Â
Zoom Lens
A zoom lens is a mechanical assembly of lens elements for which the focal length can be varied, as opposed to a fixed focal length lens. A true zoom lens also called a parfocal lens, is one that maintains focus when its focal length changes.
