.com – US Commercial Website
.net – Internet Network or Networking Site.
.biz – US Buisiness Site
.org – Organization Site – (sometimes non-profit – clubs – gov)
.info – US Information Site (no restrictions)
There are hundreds of designations. It used to be that you were wise if you took the .com for your website and also reserved (purchased) the others so no one could buy say, the .net and build a site that spins off your reputation.
It is always best to use .com whenever possible. If someone already has the .com it is not a good idea to purchase the .net (same domain name) or any of the others as then you could lose business to the .com.
.com is the most common and it is hard to remember the .net, .biz, and .info for any given website.
.org is different as people recognize it as usually NOT a business.
