ExpressionEngine channels are where your information gets stored. Within a channel you will typically find field. A field is a container that holds a specific type of information. For example, if you have a blog channel, you might have fields for the date, the title, the blog entry itself, an image, etc. Different field types let you manage your data intelligently.
