Overview |
| Originally, Robert Gaskins and Dennis Austin of Forethought, Inc. created this file format to make presentations using PowerPoint. Later on, Microsoft acquired this and now it is one of the components of Microsoft Office suite. These PPT presentations include a number of slides, where the content has images, texts with varied font style and size, hyperlinks, audio, video, charts, tables and graphs; etc. We can also apply different themes and animation effects to the text as well as to the images. This in result, can make the presentation interesting instead of dull and boring. One can bring variations to the text, that is how it enters, appears and leaves the screen. Earlier it was meant only for businesses, but now, it is widely used at every platform to showcase the knowledge or ideas effectively. |
Technical description |
| PPT consists of a number of slides which are just like different pages of a notebook. There are in-built templates which can be used to add text with titles or subtitles and images at various places. For example – there is one template for comparing the things. Therefore, two things can be compared by just adding the text. There is no need to add extra centre line to make comparison. Besides this, there comes one master slide. This slide is used to provide overall design to the presentation and it indicates how other slides should appear and work. One can also take the print to review the document. When Microsoft Office 2007 came into existence, PPTX replaced it as this new extension was based on open XML format. |

Overview |
| Files stored in this format are small in size that is why they can be uploaded and downloaded with ease. It takes less time over the internet to upload and download due to smaller size which results in saving of bandwidth. This extension is compressed using a lossy algorithm that is why there can be a reduction in the quality of the photograph. It has the ability to compress the file to one-tenth of its original size. It is widely used in emails and also when images are to be posted on websites. Digital Cameras and other photographic image capture devices widely use this JPG format. The paintings and photos of realistic scenes that have smooth variations of colour can be best illustrated by this format. |
Technical description |
| A technique used in JPEG format to compress files is lossy compression which is based on DCT (Discrete Cosine Transform) as it is the most practical Mathematical operation. The DCT actually converts each frame of the video from the spatial domain to a frequency/transform domain. It discards the information of high frequency that has sharp transitions in intensity as well as in colour hue. Furthermore, this standard defines a codec which tells how an image can be encoded into a stream of bytes and decoded back into an image. The files can be compressed in the ratio of 100:1 but that would result in the poor quality of an image. Therefore, to retain the quality of a photo, a file should be compressed till 20:1 ratio not more than that. |
