A Group is what it is. A group of people.
Groups provide many to many, two way communication. Anyone can create posts and reply with comments in a Group.
Channels provide one to many, one-way communication. Only mods can create posts. No comments are allowed by followers. While in a Group, anyone from the group can post, in a channel only channel admins can post. Followers of a channel can only view the content of the channel.
Page provides one to many communication with the difference that pages are always public. A Page is an address of any initiative. All Pages are Publicly visible. Anyone can follow them and receive updates on their wall or in email.

- Secret Groups are like private groups, with the difference that they are not publicly listed. Secret Group Owners can invite their friends by sharing the group link.
