Internet Topology & Internet Domains

Singnet Topology

SingNet Business ADSL (Dynamic IP) Internet access is a popular value-for-money Internet service for business use. Built on the latest ADSL technology, your broadband connection can be delivered from any telephone port on the wall.

SingNet ADSL service allows much greater speeds for downlink than uplink, which makes it ideal for surfing, downloading and sharing among multiple users online.

SingNet belongs to the Tier 1 network as it span national and international boundaries.

DNS

The Domain Name System (DNS) is a global database that translates domain names (such as www.internetsociety.org) to Internet addresses that are used by computers to talk to each other.

HTTP

Short for Hyper Text Transfer Protocol, the underlying protocol used by the World Wide Web. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands.

FTP

FTP is an acronym for File Transfer Protocol. As the name suggests, FTP is used to transfer files between computers on a network. You can use FTP to exchange files between computer accounts, transfer files between an account and a desktop computer, or access online software archives.

Internet Domain

Domain names are used to identify one or more IP addresses. For example, the domain name microsoft.com represents about a dozen IP addresses. Domain names are used in URLs to identify particular Web pages. For example, in the URL http://www.pcwebopedia.com/index.html , the domain name is pcwebopedia.com.

Every domain name has a suffix that indicates which top level domain (TLD) it belongs to. There are only a limited number of such domains. For example:

gov - Government agencies

edu - Educational institutions

org - Organizations (nonprofit)

mil - Military

com - commercial business

net - Network organizations

ca - Canada

th - Thailand

Because the Internet is based on IP addresses, not domain names, every Web server requires a Domain Name System (DNS) server to translate domain names into IP addresses.

Example of a DNS Name Space 

www.google.com.sg

.sg represent the top domain, followed by .com and google.
