i'm getting starting bootstrap , followed website says there 2 ways start using bootstrap on own web site. can download bootstrap getbootstrap.com or include bootstrap cdn also later you want download , host bootstrap yourself then if don't want download , host bootstrap yourself, can include cdn (content delivery network). what mean process hosting css/js file means put on own website/server. means people download website every time open up. (unless it's cached locally browser, @ least first time) cdn used people have files in cache other website visited using same cdn. (for example, google font) drastically reduces loadtimes first time visitors, risk delays out of control loading external website (if it's out, yours won't work properly!) so it's speed vs risk thing, basically.
