The second topic that we tackled is Domain Name System or simply called as DNS.
Domain Name System is a hierarchical distributed naming system for computers, services, or any resources connected to an Internet or a private network.
Domain - contains a group of computers that can be accessed and administered with a common set of rules.
Subdomain - a domain within a domain.
Domain Name Space is organized into a naming hierarchy which is used to identify domains that are at different levels in the DNS domain hierarchical tree. Their purpose is to provide name server operations, which entails mapping a user-friendly name to a routable address.
This is the DNS Domain Hierarchical Tree.
Top level domains available:
- .com - commercial organization
- .edu - educational institutions
- .org - non-commercial organizations and institutions
- .gov - reserved by the United Stated for government entities
- .net - companies involved in the Internet infrastructure
- Country names - to be used by countries
- .biz - added to accommodate businesses
- .info - informational websites
- .aero - aerospace companies
- .pro - used by professional groups
Well, there you have it. But if you have any questions just comment them and I'll ask my teacher. XD HAHA.
