1- Gateway Internet Connection

Gateway internet connection is also known as level-one connection. It allows two different types of networks to interact with each other, but the user have limited access to the internet, meaning that user might not be able to use all the tools available on the internet.

When an user initiates a Dial-up connection, the modem dials a phone number of an ISP that is designated to receive dial-up calls. Then the ISP establishes the connection within 10 seconds and it will active until the user disconnects the connection from ISP. It allows only one computer at a time and provides 56 Kbps with graphics, so this type of connection is called as ''Remote Modem Access".

3-DSL Internet Connection

DSL(Digital Subscriber Line) is a communication technology which is used to connect a computer or a router through a telephone line. It is used to transfer digital signal or use cable internet connection and can use both simultaneously. It uses dedicated pairs of copper wire to transmits data. The 30% of wire is used for voice signal and 70% of wire is used for internet access.

   DSL are of two types that are ADSL(Asymmetric Digital Subscriber Line) & SDSL(Symmetric Digital Subscriber Line). In ADSL among the 70% of internet connection there is 50% used for download and 20% used for upload & in SDSL that is 35% used for download and rest 35% is used for upload.
