URL shortener
A URL shortener is self-explanatory; it's a website that hosts a shortened alternative to a web URL.
URLs are the addresses of websites, oftem starting with "http://www." Some websites, including vast databases like Amazon, must employ extremely long URLs that are cumbersome, especially for sharing via microblogging services.
URL shorteners like bit.ly and tinyurl provide short URLs like "http://bit.ly/aBcD5" that redirect to the URL you want to share.
