To listen or view a podcast you will need what is called a podcast client. The article below tells you about what podcast clients are and how they work.
A podcast client is the software used to access and download podcasts. Podcast clients are also known as media aggregators, programs designed to automatically access an online file, or feed, and download the audio or video file associated with it. Hundreds of these programs exist, with names like IpodderX, Juice, Nimiq, and PodSpider. These podcast clients are easy to find, and because there are so many available for free, it is easy to find one that suits an individuals needs and style. These programs run on the users computer, periodically downloading a small RSS file from sites that it has been told to monitor. The file tells the program about an audio or video file stored on the server, and the podcast client then downloads that file for the user to view or listen to.
The podcast client thus allows the user to view information on a wide range of topics from their computer, without even using a web browser. Just like blogs let people find writers they enjoyed for any niche topic they were interested in, podcasts let people do them same for audio and video. Its as if a thousands of radio and television channels were created to serve every possible interest, and more were made every day. Using the podcast client to access and download the files makes it as easy to keep up with the sites one likes as it is to publish the feed.
