Different between Internet Connections

There are many ways a personal electronic device can connect to the internet. They all use different hardware and each has a range of connection speeds. As technology changes, faster internet connections are needed to handle those changes. I thought it would be interesting to list some of the different types of internet connections that are available for home and personal use, paired with their average speeds.


There are two different types of connection which is :

1. Dial-up connection
2. Broadband internet connection / direct connection


Dial-up Internet access is a form of Internet access that uses the facilities of the public switched telephone network (PSTN) to establish a connection to an Internet service provider (ISP) by dialing a telephone number on a conventional telephone line. The user's computer or router uses an attached modem to encode and decode information into and from audio frequency signals, respectively.


CONVENTIONAL DIAL UP

(to connect to the Internet, your computer dials its modem and connects to a modem attached to a computer belonging to your ISP.)

PC has to dial via a phone line to connect
Characteristics of Conventional dial-up:
 Slower, but cheaper
 Ties up phone lines
 Relatively secure from hackers
 Example :- TMNet


ISDN ( INTERGRATED SERVICE DIGITAL NETWORK)

also transfer data over ordinary telephone lines
Typically uses two phone lines to transfer data
ISDN requires a special ISDN modem
Characteristics of ISDN:
 Faster, but pricey
 Doesn’t tie up phone line
 Used by businesses and individuals




Broadband Internet service truly is the most used form of Internet access because of its high access speeds; it is offered in four different forms, DSL (or Digital Subscriber Line), also fiber-optic, cable, and satellite. The old dial-up connection is the only non-broadband internet service available, and even though it is cheaper, most Internet users are moving towards the faster broadband Internet connection.
