Explanation:

First Question: What is a wiki?

• The first option describes a tool for downloading media files (like podcasts), not a wiki.
• The second option matches the definition of a wiki: a web page/collection editable by those with browser and internet access.
• The third option refers to web application programming (like AJAX), not a wiki.
• The fourth option is about tagging content (folksonomy), not a wiki.

• LinkedIn is designed for professional networking, job searching, and business connections, making it the primary business - focused social network among the options.
• Twitter is more for real - time updates and general social interaction, though it can be used for business, it's not as business - centric as LinkedIn.
• Facebook is mainly for personal social connections, with business use being secondary.
• Flickr is for photo sharing, not a primary business tool.
• MySpace is more for music and personal socializing, not a key business tool.
