Followers are people who receive your Tweets. If someone follows you, they:

i) become your follower and will display in the 'newest follower' section shown above.
ii) receive your Tweets in their home page, phone, or any application (like Tweetie, TweetDeck, etc.) that they use.

You can't stop people absolutely to follow you but you can restrict who follows you, or sees your updates

i) protect your Tweets from settings
Protecting your Tweets means anyone who wants to follow you must submit a request for your approval. Only followers you approve can see your Tweets, which will not appear in search engines.

To approve followers

a) If you have a public profile, you do not need to approve followers.
b) If you have protected your Tweets, you can approve followers from your account home page or profile page.
c) You can also approve followers by clicking the link in the follower request email notification.
