Data transmission involves transporting information using various methods, including audio, video, and text. These methods have become more efficient with advances in technology, such as VoIP and video conferencing. The use of these methods continues to expand as new technology emerges.
Data transmission is any process that allows information of any kind to be transported using a variety of methods. The different methods employed in this process make it possible to share voice, video and text with equal ease, using the strategies relevant to the particular type of data involved. Digital data transmission occurs in a number of settings, including common vehicles such as email clients, web and audio conferencing solutions, and even file sharing. While there are several approaches to this type of information processing, they can generally be grouped into three basic categories.
Audio data transmission involves converting audio into data streams that can be easily processed and successfully delivered to a termination point. Signals of this type were once carried in analog signaling until advances in technology and fiber optics made it possible to convert audio into digital formats. Transmission of this type occurs whenever a telephone call is enabled using some type of internet stream to carry the signal. Since the latter part of the 20th century, the application of VoIP (Voice over Internet Protocol) has made it possible to use it to communicate with locations around the world without incurring high costs.
Another example of data transmission has to do with video data processing. With this application, a stream of video bits is established and used to direct data from one source point to multiple destination points. This approach allows you to enjoy online video chats with far-flung locations, as well as allowing you to use video conferencing to conduct meetings that span multiple locations. Just as advances in technology have greatly reduced the cost of long distance audio solutions, the price associated with video conferencing is a fraction of what it cost in the last few years of the 20th century.
A third classification of data transmission is the processing of text documents as part of a data stream. This application allows you to create text using some type of word processing software, save the information, then broadcast it to one or more recipients. One of the most common examples of this type of data transmission is email. Users can type text and then send it to any number of recipients. Thanks to protocols that help protect text from corruption, recipients receive the document with the same basic formatting used by the originator.
The refinement and creation of various options for data transmission continues to expand as new forms of technology emerge and enter common use. Data transfer applications that were unknown a few years ago are now used daily by business and private users. As public use of the Internet and personal computing devices continue to expand, so will the type, speed, and efficiency of various data transmission strategies.
