The dial up connection is made from a computer through modem and telephone line to the ISP's computer. The computer uses data in digital form. It means that it the computer can transmit data in 1's and 0's on and off also called digital or binary form.
On other hand, telephone lines transmit data in analog form. It means that they transmit data by sound. the telephone line from your house is joined to a special terminal that sends the data received from their computers in form of audio signals from to enter the
Public Switched Telephone Network PSTN. From PSTN, it is routed to the person or
ISP that the modem is calling through the internet. Dial-up connection face connectivity problem which the user has to deal with. Dial up connection is unstable, dialup demand phone line connection which block incoming calls access, the chief disadvantage of dialup
Internet, as compared with broadband Internet, is its slowness.
Access to modern broadband networks is essential in the information age, said FCC
Chairman Tom Wheeler. Yet 15 million Americans live in areas where they can’t get wireline broadband no matter how much they want it. These funds will jump-start broadband access in areas that would otherwise be bypassed by the digital economy.
At least 100 million U.S. homes should have affordable access to actual download speeds of at least 100 megabits per second and actual upload speeds of at least 50 megabits per second by the year 2020. The United States should lead the world in mobile innovation, with the fastest and most extensive wireless networks of any nation.
Every American should have affordable access to robust broadband service, and the means and skills to subscribe if they so choose. Every American community should have affordable access to at least 1 gigabit per second broadband service to anchor institutions such as schools, hospitals, and government buildings. To ensure the safety of the American people, every first responder should have access to a nationwide, wireless, interoperable broadband public safety network. To ensure that America leads in the clean energy economy, every American should be able to use broadband to track and manage their real-time energy consumption. Thanks to broadband, multiple users can work at the same time simultaneously. In contrast to this, if multiple computers are used on the same bandwidth in a dial-up connection, the speed will be very low.
Broadband connections have digital connections and are highly reliable. There are fewer breaks as the data transmission is fast. In dial-up modems, at times there is a data overload.
As the connection is fast, the download rate is also fast. Thus, downloading, music, files, emails, etc. is much faster in a broadband connection. In a broadband Internet connection, there are no automatic cut-offs or time-outs of the connection. The broadband connection is an “always on” connection. The broadband connection is always on 24/7 once the computer is started. Internet Protocol Version 6 is the next generation protocol for the Internet. It's designed to provide several advantages over current Internet Protocol Version 4. Pv6 addresses the main problem of IPv4, that is, the exhaustion of addresses to connect computers or host in a packet-switched network.
IPv6 has a very large address space and consists of 128 bits as compared to 32 bits in
IPv4. In addition IPV6 addressing scheme will also eliminate the need of NAT (network address translation) that causes several networking problems such as hiding multiple hosts behind pool of IP addresses in end-to-end nature of the Internet. Some of the great advantage of IPV6 is 128 bits source and destination addresses. IPV6 also have packets priority, traffic class of 8 bits, flow label and QOS management of 20 bits. IPv6 data packet is allowed a maximum of 255 hops before it is eventually discarded. An
IPv6 data packet can pass through a maximum of 254 routers before being discarded.
