What is a podcast?
A podcast is a multimedia file made available over the Internet for download and playback on your computer, iPod, or any mp3 player. They are free, and once downloaded can be played anytime without an Internet connection. When you subscribe to a podcast, you can have episodes downloaded for you automatically by iTunes, Juice (formerly iPodder), or other "podcatching" software.
What is iTunes?
iTunes is a program that manages, organizes and plays audio and video files. iTunes will "sync" your iPod, so that you can take your files with you to be played anytime, or it can play the files right on your computer without an iPod at all. iTunes is free to download from Apple by clicking here.
Do I have to use iTunes to subscribe to podcasts?
No, you can use any "podcatching" program. Another popular program called Juice (formerly iPodder) can be used in the same way with an iPod, Zune, or other portable digital media player. Juice is free to download by clicking here.
What is a mirror?
A mirrored site is an exact copy of a website's content. If you have two mirrors of a site, for example, you have 3 exact copies of the same site. This allows the website administrator to spread the burden (or "load" or "bandwidth") of the site across multiple servers, allowing for a smaller, scaled solution. You can read more on
