What is the main difference between dial up Internet access and ADSL Internet access???

I'll use Windows XP as an example to explain. Take 2 steps.

The first is hardware installation, you need to have a 56k modem, whether it is a built-in or external 56kmodemd, you must install drivers. You must install the modem driver. In the device manager, you can see that there is a message in the network device that says "...

56kb/s modem...It turns out that it's already installed and ready to start the next step of connectivity.

Then there is the software installation, which is the connection settings, because Windows XP already has built-in narrowband dialing software, you just need to set it up and you're good to go. Specifically, Control Panel --- Network Connection--- Create a New Connection--- Connection Wizard (Next) -- Connect to the Internet (Next) -- Set My Connection Manually (Select It, Next) -- Connect with Dial-up Modem (Next) -- ISP Name (Dial-up Internet) (Next) --** Number (16300) (next) - Account password (both are 16300) (next step) - Done (add a shortcut on the desktop to tick).

And that's it. Many times the narrowband can't be dialed, so you have to be patient to try, as long as the modem makes a "chirping" sound to prove that it is dialing, and the "rustling" sound proves that the dialing has been successful, but it is so expensive, almost 6 yuan more than an hour.

Ask the telecommunications department! Or the Netcom department!

It's not broadband how do you dial.

Using the built-in connection of the system, after the connection is established, you can enter the account password to dial the number.

1. Different ways to access the Internet.

1. Dial-up Internet access: Internet access through external or built-in modem and a ** line.

2. ADSL Internet access: a way to access the Internet through asymmetric digital user lines.

Second, the principle is different.

1. Dial-up Internet access: Apply for your own from the local ISP** provider, or buy a network card, have your own username and password, and then connect to the Internet by dialing the ISP's access number.

2. ADSL Internet access: use digital coding technology to obtain the maximum data transmission capacity from the existing copper ** line, and at the same time do not interfere with the conventional voice service on the same line.

Third, the characteristics are different.

1. Dial-up Internet access: Through PPPOE technology and broadband modem, you can realize personal authentication access to high-speed broadband network, and create a virtual dial-up connection for each user, so that you can connect to the Internet at high speed.

2. ADSL Internet access: data signals and audio signals are modulated in their respective frequency bands without interfering with each other by the principle of frequency division multiplexing, and you can dial or receive ** while surfing the Internet, which avoids the trouble of not being able to use ** when dialing up the Internet.

ADSL dial-up refers to connecting to the Internet by dialing the access number of the ISP.

At present, users of dial-up Internet access in China basically use the full name of Point to Point Protocol over Ethernet based on PPPoE protocol, which is a protocol that combines Ethernet and PPP protocol.

PPPoE technology and broadband modems (e.g., ADSL modem) enable personal authentication access to high-speed broadband networks, creating a virtual dial-up connection for each user, so that they can connect to the Internet at high speeds.

Dial-up Internet access has been largely eliminated for a long time. Nowadays, home Internet access is basically broadband. Common ones are ADSL technology that uses ** lines, the latest fiber-to-the-home, cell fibers and so on.

Analysis: ADSL technology is a technology for asymmetric digital subscriber lines to achieve broadband access to the Internet, ADSL as a transport layer technology, make full use of the existing copper line resources, and provide a bandwidth of 640kbps uplink and 8Mbps downlink on a pair of twisted pair cables, thus overcoming the traditional user in"The last mile"of"Bottlenecks", to achieve broadband access in the true sense.

The principle of ADSL:

Traditionally, ** systems use the low-frequency portion of the copper wire (band below 4kHz). ADSL uses DMT (Discrete Multi-Audio) technology to divide the original ** line from 0Hz to the frequency band into 256 sub-frequency bands with a frequency width. Among them, the frequency band below 4kHz is still used to transmit POTS (traditional ** service), the frequency band from 20kHz to 138kHz is used to transmit uplink signals, and the frequency band up to 138kHz is used to transmit downlink signals.

DMT technology adjusts the number of bits modulated on each channel according to the conditions of the line in order to make better use of the line. In general, the greater the signal-to-noise ratio of a sub-channel, the more bits are modulated on that channel. If a sub-channel has a poor signal-to-noise ratio, it is discarded.

Currently, ADSL can achieve data rates of 640kbps uplink and 8Mbps downlink.

As can be seen from the above, for the original ** signal, the original frequency band is still used, while the ADSL-based service uses a frequency band other than voice. Therefore, the original ** business will not be affected in any way.

Transfer speed: ADSL dial-up Internet access is usually faster at up to 24Mbps, while ISDN can only reach up to 128Kbps.

Cost: The cost of ADSL dial-up Internet access is comparatively lower, whereas the cost of ISDN dial-up Internet access is higher.

Network connection mode: ADSL dial-up Internet access is connected to the network through ** wire, while ISDN is connected to the network through digital ** line.

Number of users: ADSL dial-up Internet access can support multiple users to connect at the same time, while ISDN usually only supports one user connection.

Stability: ADSL dial-up Internet access has relatively poor stability and is easily affected by network congestion and other factors, while ISDN dial-up Internet access is more stable and reliable.

What is the difference between ADSL dial-up and ISDN? IS DN dial-up is a technology that preceded ADSL dial-up. The main difference between IS DN dial-up Internet access is that the bandwidth rate is slow, and it is not the same level as ADSL dial-up Internet access.

Can fiber optic dial ADSL?

Can optical fiber adsl dial-up home optical fiber connection is a simple optical modem, the cat out of the network cable directly connected to the computer, the computer needs to establish a dial-up connection, in the computer input broadband Internet access and password dial-up Internet.

There are three types of Internet access used by optical fiber connection routers: PPPoE dial-up (ADSL dial-up, broadband dial-up); Dynamic IP (automatic IP address and DHCP); Fixed IP (static IP) When choosing the Internet access method, you can remember the following selection principle: 1. If you have a broadband account and broadband password; Select PPPoE dial-up (broadband dial-up, ADSL dial-up).

2. If the broadband operator provides the IP address, subnet mask, gateway and DNS server address; You should choose a static IP (fixed IP). 3. If you do not have a broadband account or password; There are also no IP addresses, subnet masks, gateways, and DNS. In this case, you should select dynamic IP address (DHCP, automatic IP acquisition).

Hello. Leased line broadband generally does not require dial-up. Many years ago, the broadband that became LAN was actually a large local area network, and it did not require dial-up.

Dial-up is now generally required for broadband use by individuals.
