Dial Up Connection:
This is oldest method of internet connection used in earlier days. Some of them are still sticked to Dial Up connection for no reason. Dail Up connection offers very negligible speed which may sometime make us to get frustrated of its slow speed. Main and most important disadvantage which leads to the decline of dial up connection is that no router allows you to share the dial up internet. This is because speed you receive from dial up connection is very negligible and it will not be nothing if it is still shared.
Broadband Connection:
Broadband connections gives more bandwidth and it is comperatively cheaper than other connections. Broadband connection will allow the user to use both the telephone line and the internet connection at the same time. Broadband offers two ways of authentication.
Authentication Type:
1) Session authentication
2) Username and password authentication.
Session authentication:
Normally, computer or a laptop connected to the broadband connection get an ip address automatically. But however it will allow the user to get online without authenticating their authentication server. To authenticate their server they would give an username and password. It is necessary for us to provide an username and password where it is prompted to authenticate your server. Then you will be granted access to use the internet connection.
Username and Password authentication:
Provider allows you to connect to the internet only when you are authenticated. This type of connection will not give you any ip address unless you are completely authenticated. Once you are authenticated, you are ready to get online.
Cable Connection:
Cable connection is type of internet connection which is widely used among all people throughout the globe except India. In India Cable Service providers are very very less in number. Cable internet connection works on mac-address authentication. The type of ip address which you get from Cable connection will be public address. Public address is very important for one to use their X-box, Ftp, Media-Server, Web Server hosted on your computer.
Mac-Address Authentication:
Mac-Address authentication allows an user to get online based on their mac-address which is registered on the service provider database. This mac-address will be uploaded into the service-provider database by the engineer who install the service for you or the software that comes with the modem.
DSL Connection:
DSL connection is the competitive Service to Cable Connection. DSL connection both Public Ip address and Private Ip address. There are two modes available in DSL connection.
1) Bridge Mode.
2) Nat Mode.
Bridge Mode:
Bridge Mode allows you to get an public ip address but it requires authentication.
Nat Mode:
It will give you a private ip address but doesn't require any type of authentication which mean the username and password will be already entered into the modem.
SATELLITE CONNECTION:
This is the type of connection which is becoming popular all over the world. Reason behind why the people prefer this connection is for its outstanding speed. But comparatively it is very expensive than any other connection. This connection also allows you to get a public ip address. But the main drawback with this connection is that most of the router doesn't support this type of connection.
Wireless Internet Service:
This is special type of internet connection which allows the user to get internet although they are geographical isolated from the heart of the country. This will allows you to get either a public ip address or private ip address depending upon the provider. There are only few routers that support this type of Internet service.
