Can someone help me with this? There is a program named Namebench that told me that there is a faster DNS but I thought that you just connect right to the ISP like Verizon for example. Can someone explain this? Thanks.

Quite simply because I don't have much time.
DNS converts friendly domain names such as mywebsite.com into the real IP name of the server 127.0.0.1. This means then when you want to connect to mywebsite.com you don't have to type the IP in. It would be hard to remember all the IP names of your favourite websites.
DNS servers such as openDNS have servers that cache all of these names so you simply connect to a DNS server that is close to you to find out the IP of the website is before going to the site. The faster this lookup then the faster your internet will be (within reason)
The ISP often provide their own DNS servers but these may not be the best and that is why people switch to ones like openDNS or google public DNS.
The ISP simply provides the internet connection allowing you on to the world wide web and sets a speed to which you can browse said web.
Hope this was not too basic!
