A Guide to the ways people can connect to the internet as the technology grows, so we have the largest Internet, better and faster. Over the years, so the content is presented through the Web has changed drastically. Ten years ago, is able to focus the bold, colored text was something to admire, and now flash animation, online gaming, video streaming, websites database driven, e-commerce and virtual offices - with name but a few - is setting standards. Need for speed has changed the options available to consumers and businesses both in terms of how and how quickly can connect to the internet. As technology changes at a rapid pace, so even the Internet. Speed link below provides an overview of the average maximum speed at the time of publication. This undoubtedly will change over time and Internet connection speed also varies between Internet Service Providers (ISP
1>> Analog (up to 56k)
Also called dial-up, it is both economical and slow. Using a modem connected to your PC, users access the Internet when the computer dials a phone number (which is provided by your ISP) and connects to the network. Dial-up is an analog connection, because the data is sent to an analog public telephone network. Analog modem connection takes digital data and vice versa. Because dial-up access uses normal telephone lines to the quality of connectivity is not always good and data rates are limited. Typical dial-up connection speeds ranging from 2400 bps to 56 Kbps
2>> ISDN
Integrated services digital network (ISDN) is an international communications standard for sending voice, video and data over digital telephone lines or normal telephone wires. Typical ISDN speeds ranging from 64 Kbps to 128 Kbps.
3>> B-ISDN Broadband
ISDN is similar in function to ISDN, but the data transfer over fiber optic lines do not, normal telephone wires. SONET is the physical backbone of B-ISDN transport. Broadband ISDN is not widely applied.
4>> DSL
DSL is also called an always on connection because it uses existing 2-wire copper telephone line connected to the starting point and will not take your phone as a dial-up is not. No need to dial into your ISP as DSL is always on. Two main categories of DSL for home subscribers are called ADSL and SDSL.
5>> ADSL
ADSL is the most established types of DSL in North America. Short for Asymmetric Digital Subscriber Line ADSL supports data rates of 1.5 to 9 Mbps when receiving data (known as the rate of downstream) and 16-640 Kbps when sending data (known as rate upstream). ADSL is a special ADSL modem.
6>> ADSL 2
ADSL 2 A is an extension of ADSL broadband technology that provides subscribers with a speed significantly faster download compared to traditional ADSL connections. ADSL 2 works the same way as a filter to separate ADSL is installed on the customer hotline telephone existing copper lines (POTS) between normal phone (voice) and ADSL 2 disruption. ADSL2 + service is the most commonly offered in more populated metropolitan areas and subscribers must be in close geographical locations of the providers Central Office ADSL2 + service to you.
7>> SDSL
SDSL is still very common in Europe. Short for symmetric digital subscriber line, a technology that allows information to be sent over existing copper telephone lines (POTS). SDSL supports data rates up to 3 Mbps. SDSL works by sending digital pulses in the field of high-frequency telephone wires and can not simultaneously with voice connections that operate over the same wires.
