ADSL can provide users with more than 6Mbps of data transmission bandwidth, this condition is enough to achieve Internet access, video on demand and access to the local area network. ADSL can achieve bidirectional transmission rate of 640 Kbps in interactive mode. ADSL technology has increased the bandwidth of the existing public telephone network data transmission 50 times times. The transmission of voice, text, and low-resolution images is no longer limited by bandwidth.
ADSL technology can b
Article title: Linux allows you to access the Internet easily-configure a dial-up network in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

, it is particularly suitable for personal home users and small-sized enterprise/group users to access the Internet.2. Do I have to charge a telephone fee when I use ADSL to browse the Internet? No. Because the INTERNET access through ADSL is not connected to the INTERNET through the telephone exchange network, but occupies resources of the PSTN line and broadband network, you need to pay the ADSL monthly rental fee.3. What are the advantages of ADSL access compared with ordinary dial
There are multiple access methods for accessing the Internet at ordinary times, and the access speed provided by the ISP service provider is different from the download speed, which is hard to understand. The following lists the Internet access speeds for accessing the Internet:1. PSTN (published Switched Telephone Network, public telephone exchange network) technology uses PSTN to implement user access through MODEM dialing. A
In the rapid popularization of broadband network today, our hands of the modem seems to have "Lianpo old", using it on the internet is too slow, after the brutal elimination, accompany us countless days and nights of kittens will have no value? Of course not, we can also send and receive faxes through the modem in your hand, The effect is very ideal, so that we can make our
1. ADSL FAQ Classic Fault ADSL is running on the original telephone line of a high-speed broadband Internet access, it has the advantages of saving investment, fast Internet, simple installation and so on. At present, many local area networks, especially Internet cafes, use this method. Of course, the Internet in this way the fault is also more, the following for everyone to talk about ADSL troubleshooting methods and examples. the factors that cause ADSL fault The common hardware faults of
computer connected is not a problem, but it does not achieve normal connection, and the other computers on the LAN can connect to the Internet normally.
Workaround: Handle this wireless router configuration problem by connecting the computer that is bound to the MAC address to the router LAN port (but the wireless router does not connect to the modem or ISP's wiring), and then, using the MAC address cloning function of the wireless router, Copy the
1. Shared Internet access

If you want to add an additional computer to share the Internet with ADSL, You need to purchase two more NICs, one installed on the Internet access computer, the other is installed on the computer to be shared (hereinafter referred to as the client. We recommend that you purchase a 10/100 Mbps white adaptive Nic. It is worth mentioning that if the ADSL modem is an external Ethernet interface, there will
Now there are more and more users using the ADSL Broadband Network, and the maintenance of the ADSL equipment has become a problem that cannot be ignored. Only by maintaining it well can you not only save your "Broadband Journey", but also prolong your life.
Routine Maintenance
The necessary routine maintenance for ADSL equipment can not only reduce unexpected faults, but also ensure smooth network and improve the service life of the equipment. The main routine maintenance includes the following
Asyuncrical Digital Subscriber Loop Asymmetric Digital user line Loop (ADSL) is a member of the xDSL family and is hailed as "express on modern information highway" by Western countries ". Because of its high downlink speed, high frequency bandwidth, and excellent performance, it is favored by many users and has become another new and faster and more efficient access method after MODEM and ISDN, it is also the most widely used access method in China.
, especially the latter. They have different transmission features, market positioning, physical location, and problems to be solved, in the future, many technologies may coexist in actual access networks. This article will introduce some major Wired Broadband Access Technologies.
At present, the main wired broadband access technologies include: ordinary Modem, N-ISDN narrowband integrated business Digital Network), Cable
used to debug the kernel running on the target computer. For better performance, you can use a well configured computer as your development computer.
0 Modem cable (Null modem cable)
A 0 modem (Null modem) is a means of communication using a RS-232 serial cable to connect two computers. The original RS-232 standard
hard disk devices in this computer is not a conflict of the problem, then where is the problem? So the author again installed the flash drive driver, The problem is still unresolved.The author once used in some old machine on this flash drive, can be used normally, in this machine should also have no problem. So I think there may be a problem with the flash drive, in order to verify the flash drive, the author will be inserted into the latest computer flash drive, the results of the flash drive
Recently too busy, there is no time to write about the ucos-ii transplant, first of all the work is easy to make a mistake in the knowledge points recorded, about the CTS and RTS.
In RS232 the CTS and RTS have a clear meaning, but since Hayes (HAYES) introduced smart Cat (SmartModem) is a bit confusing, but now this meaning for the mainstream, the main chip manufacturers of the UART controller flow control basic use HAYES Modem flow control interpreta
What about internationalization and localization? It is to create files of different national languages in the resource folder res. The naming rules of these national languages are stipulated. For details, see Table 6-1. When the user sets the language of the mobile phone, the program can load the corresponding language file based on the language selected by the user. The user feels that the program is localized, and for developers, the program is internationalized.In this example, a registratio
