Questions about Adsl and Lan?

Hello and happy for you :

You said that the speed of your telecom 1m ADSL broadband ** is 80-100k, this speed is normal, because according to the data ** program: 1m=1024k so 1024k 8bit (the smallest unit of data is bit) so it is equal to 128k s, plus line loss so it is normal to reach 100k!

2 reasons 1LAN broadband uses optical fiber lines to the community, and direct network cables are used in the switch to the home, so the up and down speed is the same, and the transmission has an advantage over ADSL, because ADSL uses the first line, no matter what, its transmission quality is not as good as that of optical fiber lines.

2.This is caused by the bureau (telecom or Netcom and other ISPs) did not limit the port, if it strictly restricts the LAN broadband of the community, this situation will not occur, one of the biggest features of LAN is that it is shared, if the user Internet traffic is too large on the LAN broadband switch of your friend's house at night, the network speed of your friend's house will slow down.

This is a different access mode of broadband, adsl is **line access, this broadband is just a broadband concept compared to the original**line cat,56k。 It's the slowest in broadband right now.

Your friend's LAN is optical fiber + LAN access mode, the backbone is optical fiber, and the data line access to the user is not a fiber optic network in the full sense, it is the main broadband mode now, and the network speed is compared with ADSL, you should be very impressed.

Wait, in less than 2 years, fiber to the home in the real sense, hehe, friends, that's the real sense of broadband. The so-called information superhighway is like this, the network speed will be several times that of optical fiber + LAN, patriotism depends on their own actions,

Generally speaking, the speed of 1m is about 200. In the official ** of the wire can be saved with the right click, or, at the same address with the same software and settings**, the comparison will come out, and, the *** bad of the **line is also related to the speed.

LAN (Local Area Network) mainly uses Ethernet technology, and uses high-speed switches at the central node to provide broadband access from network cable to home. Generally, the access mode of sharing the Internet speed is virtual dial-up, and a dial-up client software is installed on the computer, and the password of broadband Internet access can be accessed.

LAN mode is the use of Ethernet technology, it is the use of optical cable + twisted pair to the cell for integrated wiring, usually users will get more than 10M shared bandwidth, the ideal speed will be nearly 180 times faster than the current dial-up Internet speed.

**The time of a blockbuster movie is about 5 to 7 minutes, and the speed advantage is obvious. Considering that the scalability of the LAN access mode is relatively good, with the increase of users, it can be upgraded to more than 100M according to demand, so it is still very advanced in speed.

The series filter (not the splitter) in the landline ** line, maybe you are wrong. In addition to the different names, the shape of the separator or the filter is also different. One in and one out is the filter, the 3 heads are the separator, the separator is an incoming line divided into 2 ports, one to connect the cat and one to all the ** machines.

The connection method of the mother and child machine is correct, as long as the mother machine is connected to the filter. The phenomenon of breaking as soon as a dozen ** is really the same as the fault phenomenon of not installing a filter.

It can be shared, two network cards, and two networks can be connected to each other. Note that 2 networks cannot be the same network address.

For example, if your cat's address is the gateway of the community broadband, you will not be able to access any network. You can change an address, but if the cell gateway is not easy to change, change your cat address. Let's say change to.

You can also turn off a network card when you use it, and turn off another network card if you want to use any network. Disabling the NIC by turning it off. When the online neighbor finds the card, it can be operated--- disabled or enabled.

Thank you for your question.

The first question, you should still check the problem of the splitter, the second question, unless you install two network cards, otherwise it is impossible to share.
