10. Accessing ISPs
Consumers can access their ISPs through different means such as:
Dial-up connection
Broadband technologies
GPRS (General Packet Radio Service) & 3G (Third Generation mobile telecommunication) services for mobile access

11. Dial-up Connection
Dial-up access is a form of Internet access via telephone line.
The client uses a modem connected to a computer and a telephone line to dial into an ISP's node to establish a modem to modem link, which is then routed to the internet.
Dial-up connection is the slowest internet connection, it is times slower than broadband connection.
It is not possible to make or receive phone calls when connected to the Internet.

12. Broadband Technologies
Broadband technology refers to the means by which access can be made faster with greater bandwidth. There are several such technologies, of which the main types are :
Digital Subscriber Line (DSL)
Cable Modems
Other means

13. DSL Limitations of cable infrastructure
High-bandwidth Internet access over existing phone wiring
Most commonly used means of broadband technology
It modulates binary data into sonic frequencies above 20 kHz
This enables user to make or receive calls when connected to Internet without interference
Speeds upto 6 mbps can be delivered

14. Cable Modems High speed Internet access over cable modems
Uses the Hybrid Fiber Coax (HFC) or the all- coaxial infrastructure of the local cable provider
Speeds range from 500kbps to 30mbps
This bandwidth satisfies the current scale requirement though it is expected to face scalability issues in future

15. Other Broadband Technologies
These include:
Passive Optical Networks (PON)
Wireless LAN and LMDS (Local Multipoint Distribution Service)
Asynchronous Transfer Mode (ATM)
10/100/1000 Mbps Ethernet
Other connection means include connection via satellite, electric power lines etc.

16. The Future of ISPs? Depends on competitive forces Increasing demand
ISPs will become increasingly important as more information is communicated by the Internet
Increasing research in ISP sciences
An interesting new development is the introduction of new domain names. Instead of the traditional .com, .org and .net there is now .biz and .info.
