What is DNS? How do users benefit from it? Provide a brief description of the DNS process to resolve a URL to its IP address.
Domain name systems (DNS) allows for an IP address to be assigned to a computer name or domain name. This system stores given names paired with IP addresses, which make identifying a computer on a network that much simpler. DNS follows an top-down heiratage, starting at the root on to top level, secondary level, subdomain level (optional), and host level. Each of these levels are separated by periods in the IP address. For example, .edu (top level), phoenix (secondary), classroom (subdomain), and https:// (host).
You are absolutely correct in describing the functions of DNS. I could not imagine life without having a system like this that allows us to simply type in the name of where we are wanting to go, such as facebook.com, and letting the computer and the servers look up proper IP address to get us there. Without the benefits of DNS, we would be left trying to memorize all of the IP addresses to where we wanted our browsers to take us to which would not be very much fun and actually quite challenging
I would have to agree with you on this subject. I rarely type in the web addresses for my favorite sites as it is because they are saved in my favorites bar. The only issue I can see with this would be attempting to remember which number led to which site, but if we were able to attach a name to it, like we do with telephone numbers, it would be easier. Although, I can see how people today would have a hard time with this. Most people, I have even been guilty of this, do not remember telephone numbers, because they are stored in their cell phones. Have you ever seen someone who needs to make a call and their cell phone is dead? The only numbers they can seem to remember are their parents or grandparents because they learned them years ago. Any number they have acquired in the last ten years is rarely memorized.
