They’re not the same. A web host will usually have one or more servers devoted to hosting sites, and at least one DNS server. The hosting servers are where your website is stored when you pay them to host your site.
A DNS server or Domain Name Server is part of a huge database spread out across the Internet. Any time you visit a site by typing in a name, like www.google.com or www.yahoo.com, the DNS server converts that name into an IP address.
The reason is simple. Computers communicate over the Internet using IP address, nothing more, but IP addresses are difficult to remember (209.85.135.99 for www.google.com and 87.248.113.14 for www.yahoo.com). DNS allows you to use human-readable names instead. The DNS server resolves the name to a computer-friendly IP address and saves you the trouble of remembering.
Copy the IP addresses for Google and Yahoo and paste them in your browser’s address bar. They work just like a URL. They’re just not as easy to make sense of.
A DNS server resolves human readable host names (actually fully qualified domain names) to IP addresses. For example if you type http://www.yahoo.com into your browser window, DNS tells your machine that that is reachable at 208.69.36.132. (That’s only one of the many IP addresses that you can reach http://www.yahoo.com at; there are many others as well.
A web hosting server is a server that hosts web pages. When you go to http://www.yahoo.com you are hitting a web hosting server.
