Domains are areas of interest or areas to be managed They are relatively arbitrary, but suggested domains include the organization, infrastructure, applications, and data
A domain is a specific virtual area within the Internet, defined by the "top level" of the address or URL (Uniform Resource Locator) The top level is the end of the address; example: "whitehouse gov" In this example, the top-level part of the domain is " gov", indicating a US government entity The "whitehouse" part is the second-level domain, indicating where within the " gov" domain the information in question is to be found Other common top-level domains include " com", " net", " uk", etc
Sometimes people who want to create a domain are interested in setting up a web site Interestingly enough, a domain does not point to a web page! A domain is more like a collection of computers A specific domain name (for example, www domain org) only points to an IP address The server that owns that IP address must be configured to serve the proper pages
A logical tree-structure naming convention to provide unique names for computers on the Internet (and other networks)
