A presentation program is commonly used to generate the presentation content, some of which also allow presentations to be developed collaboratively, e.g. using the Internet by geographically disparate collaborators. Presentation viewers can be used to combine content from different sources into one presentation.
Data communication, including data transmission and data reception, is the transfer of data, transmitted and received over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires , optical fibers , wireless communication using radio spectrum , storage media and computer buses .
LibreOffice Impress, one of the most popular free and open-source presentation programs. In computing, a presentation program (also called presentation software) is a software package used to display information in the form of a slide show. It has three major functions: [1] an editor that allows text to be inserted and formatted
The presentation layer handles protocol conversion, data encryption, data decryption, data compression, data decompression, incompatibility of data representation between operating systems, and graphic commands. The presentation layer transforms data into the form that the application layer accepts, to be sent across a network.
A datagram is a basic transfer unit associated with a packet-switched network. Datagrams are typically structured in header and payload sections. Datagrams provide a connectionless communication service across a packet-switched network. The delivery, arrival time, and order of arrival of datagrams need not be guaranteed by the network.
In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver. Flow control should be distinguished from congestion control , which is used for controlling the flow of data when congestion has actually occurred. [ 1 ]
An example of a presentation service would be the conversion of an extended binary coded decimal interchange code (EBCDIC-coded) text computer file to an ASCII-coded file. If necessary, the presentation layer might be able to translate between multiple data formats using a common format.
The primary electronic media sources familiar to the general public are video recordings, audio recordings, multimedia presentations, slide presentations, CD-ROM and online content. Most new media are in the form of digital media. However, electronic media may be in either analogue electronics data or digital electronic data format.
