About broadband, thank you, so much more!

ADSL stands for Broadband. 1M is your bandwidth, which is the speed of Internet access.

LAN stands for Local Area Network··· LAN doesn't matter what it is... It's useless at home... It's a sign. 1 trillion is 1024kb is 1m=1024kb··· 1 trillion = 1 mbu disk 128 trillion refers to capacity... 1g=1024mb··· That's 1g is equal to 1024 trillion.

Do you understand? ~~

It doesn't seem to be a concept ADSL1M LAN 1M This represents the maximum downlink speed of ADSL 1M

This refers to bandwidth.

The U disk refers to the capacity, and the 1G of the U disk is 1024M

m is the meaning of trillion.

Indicates the transfer speed.

The M and U sticks here are not the same concept, but here they are units of transmission speed.

The USB stick is the storage unit.

1。ADSL1M lan 1m refers to the speed of the Internet.

It's how much data is transferred in a certain amount of time. I don't really understand the specifics. That's what it means. 1m=1024k, then it's adsl1m lan 1m, this is more expensive than adsl 768k lan 1m.

2。It shouldn't be a matter of time. 1g=1024m

The m here is what you said, but the M unit here represents the network speed and bandwidth, which is a unit to measure the speed and slowness of network traffic!

Netcom tells you that m refers to the speed of circulation, which is the bandwidth that is usually referred to as speed, but it is said to be 2m or 4m, and the speed is generally limited.

The m of the USB flash drive refers to the capacity, that is, the volume of 1g=1024M

Broadband, English name: broadband, refers to a relatively wider frequency band. In digital communication, it usually refers to the bandwidth that can transmit more than 2Mbit s; Or refers to the upper limit of the dial-up Internet speed of 56kbps as the boundary, the access of 56kbps and below is called "narrowband" (using dial-up Internet access), and the access mode above is classified as "broadband".

There is no strict definition of broadband. From a general point of view, it is a dynamic and developing concept that can meet the bandwidth required for transmission on the network that people can feel. At present, broadband for home users means that the transmission rate exceeds 1m, which can meet the needs of a large amount of information transmission such as voice and image.

Broadband access to the Internet, which at the earliest required ** cable, morle, and computer. With the development of science and technology, there is no need for a first-class line, and users are directly connected through a dedicated line or optical fiber, and the terminal has also canceled the general morle, and the connection is to an optical modem. Some completely cancel the cat, and only enter the paid account and password in the signal received by the terminal to log in to the network.

It refers to the use of ** cable and morle to connect the computer to the network.

1) If it is a problem with the broadband itself, first directly connect the broadband network cable to test, if it is a broadband problem, contact the broadband customer service to solve it.

2) If it's a problem with the router, such as teasing the fruit that can be used originally, it can't be used for the time being, my own practice is to disconnect the power of the router and plug it in, and I'll take a look. In there is a factory reset settings, from the new strict according to the manual settings can be used, I don't understand, it is not recommended to set up at will (this is under the premise of the correct physical connection, sometimes the router is slow or failed to find the IP address, not that the router is broken).

If it can't be solved all the time, it is recommended to call the customer service of the router, they have **** guidance, I encounter a problem that I can't solve by myself, it is very useful to consult the advice they gave, and they will give the correct advice for your settings or operations.

3) If you turn off the wireless switch, turn it on, if the mountain Luzi is connected to the wireless with software, it is normal for the software to be difficult to use and often have problems, there is no better way, use a router. In addition, it is caused by the network card driver is not or is not suitable, and whether there is a problem with the network cable interface or network cable.

4) If it is caused by a system problem, it is recommended to restore the system or reinstall it.

If a message "request timed out" message is displayed, the other party cannot accept the data sent. Of course, in this case, it is likely that the network is faulty, but this does not mean that the network must be unavailable. Because it could be caused by other reasons.

If the other party shuts down, disables the network card, or unplugs the network cable, no matter what you do, no connection message will be returned. Know that the simplest is often the most overlooked.

Firewall blocking.

When a firewall is installed, it will generally automatically intercept pings from the network when the firewall is working, making it unresponsive. When a firewall is installed at the same time, it can also cause the shared file to be inaccessible. Therefore, you should ask the other party to turn off the firewall before using the ping command to check it.

IP security policy restrictions.

For many experienced NMS, they add IP security policies to the server to filter ICMP packets so that the ping command cannot be responded to, and the error message "request timed out" is returned.

The gateway is set up incorrectly.

This situation mainly occurs when pinging an external network address. This is because when the gateway is set up incorrectly, the packets sent by the ping cannot go through the gateway. Therefore, it is necessary to check that the gateway settings of the local machine and the configuration of the remote gateway are correct.

Generally speaking, only by excluding the above reasons can you preliminarily determine that there may be a problem with the network connection based on the "request timed out".

Based on these circumstances, you can check it out.

Professional Answer:

1: Is the type of broadband you use at home the same as your classmates? If one railway passes and one telecommunications, there is still a difference.

2:2m's upper limit is 256k, support 300k, the recent telecom free upgrade 4m activity, nominally 2m, the speed can reach 4m, this has a preferential application.

3: It is also possible that your router has been rubbed by the network, you can change the wireless password to a longer time and try again.

4: The best way is to move your computer host to your classmates to try it, if you move to the same school quickly, then there is a problem with your network, and it is very likely to be rubbed online. If not, then ask the operator to test the line.

1. Telecommunication is fast, but movement is slow, this is the truth.

2. I think the first one is very important.

3. Recently, it has slowed down to see if no one is rubbing the Internet, which has slowed down, if so, change the password.

Have you ever been on wireless, will it be stolen by others, if it really doesn't work, let the telecom people take a look.

The ultimate speed of 2m is 256k s. Your speed has been exceeded, and your fellow student 500k s means at least 4m of broadband.

It's your classmates who are abnormal.

It's really hard to say, the installer has some money to install a broadband, but it also depends on how much money it is! Let's change a position to illustrate, if you are the installer, you will get a salary of 18 yuan for installing a broadband, but you can install an average of 8 per day, that is, 1 hour a, now you go to a user and find that there is no wiring and need to pull a long and long leather wire to reach the user's home, and there are many obstacles in the middle, etc., in short, it is very complicated, you preliminarily calculate that it takes 4 hours to install this broadband for this user, and it will be very tired. And the user's line is too far away from the computer room is likely to cause the line to be substandard after installation, if it really does not meet the standard, Telecom will deduct 100 yuan from your job. Okay, in this case, you say you can't pretend to be this user.

Finally, you can say to Telecom that the line here is not good, the broadband line is not up to standard, and there is no wiring, even if you want to install it for him, you first need to build a broadband computer room near the user's home, and increase the number of wiring near the user's home, and you need your company's engineering personnel to construct. If the construction is completed, it can be installed, so your company will not punish you if you don't install this user in your current situation. Now, you say you don't have to install this user.

In fact, there is no problem if you want to install, that is, you can get the person, you either get the installer, how to get it depends on what I said above to find a way, if you want to get the leader of telecommunications, anyway, if you get the person in charge of this thing, you will be able to install it for you, isn't it just to pull the line, the cable is not good, just put a special one with Wu Zhi optical fiber, it is a matter of cost and human feelings, you can't get the person, you don't want to install it, change a network service provider.

What kind of broadband are you installing?,Telecom or Unicom,If it's mobile broadband, you don't need a port.,You only need a TV interface to install it.。
