Customer Support portal Query

[Snow preck]

Please help me understand : Customer Support Portal default configuration provides the following channels to interact with customers? 

 A. Web

 B. Social

 C. Chat

 D. Email 
As per my knowledge i feel - (Web, Chat, Phone, emails) and not social, Can some one help me understand how answer is : (Chat and email and not web ), Just help me understand if web portals are differing from web, if so please explain
For reference:

Yes, for social channels you need to activate the plugin, but out-of-the-box (OOTB) there are 3 channels: chat, phone, and email.
