B. CONTENT I. IDENTIFY THE PURPOSE AND TYPES OF DNS, INCLUDING EXPLANATIONS ON HOW DOMAIN NAMES ARE ORGANISED AND MANAGED (P1)
- Website. Website, also known as website, is a collection of sub-sites, including text, images, videos, flash, etc. WEBSITE is only located in a domain name or subdomain hosted on servers running online on the World Wide transmission of the Internet. - How the website works? To easily visualize how a website works, you can refer to the diagram below (as if the website is installed on a separate server). First, the user enters the browser an address of the form: https://hocban.vn, actually you just need to type "lapo.vn" and the browser will understand and change it to the link above. The browser sends a request to the DNS server. The DNS system returns the results of the domain name analysis in the sent link, which is lapo.vn, it has a server address of 210.212.143.153 (this is already assigned at registration, the DNS server just needs to remember). After receiving the IP address - where to get the data, the browser will find the received IP address - the server containing the website content. The web server receives the request to retrieve the website content and it sends a set of files including HTML, CSS , other multimedia files such as audio, images (if any) to the browser; i
The browser "translates" the files that the server has sent into the web page we see on the screen.
- Domain Name System What is domain name? A domain name is the name of a website operating on the internet, acting as a static, fixed address. Just like your home address or zip code helps satellite routers navigate your goods, a browser needs a domain name to navigate to your website (web server). o How the domain names are organised and managed? The operator of the domain name organization is responsible for maintaining administrative data for top-level domains or lower-level domains. This unit is licensed to operate through ICANN. The domain management organization will have the authority to manage the top-level domains, and each organization manages the administrative data for its own domain names. The management includes container files that contain nameserver addresses and information about domain name registrants. Domain name organizations need to define requirements for the registration of private domain names so that they can use their domain extensions. Example to help you understand what a domain name registrar is: Some TLDs require the domain name registrant to be located in a certain country, etc. Sometimes the domain name registrar will enforce certain conditions. service terms for domain names that do not comply with the above provisions. o What is Domain Name System? o Purpose and type of DNS i
