What is the difference between 1M and 2M bandwidth?

To use an analogy: 1m is a two-lane road; 2m is a four-lane road. When you have a small task, there is no difference between the two, but when there are many tasks, the productivity of 2M is much faster.

If you use it alone, 1m is enough to meet the requirements. The difference is very simple, for example, in the next movie, 1M will reach a maximum of 1000+KB per second, and in the case of doing nothing, it must be rich in resources, in the same way, 2M can reach 2000+KB per second.

Of course, the more bandwidth, the faster it is!

Personally, I suggest it, is it telecom, telecom's broadband 1m is 900, is 999, 2m is 1499 yuan, 1m and 2m can only reflect the advantages when the file is large, if you don't like to play games, you need more than 2m, the speed starts from 1m120kb s, is 180kb s, 2m is 240kb s, so the comprehensive cost performance is the highest.

One trillion and two trillion refer to the traffic transmitted per second when the network speed is the fastest, of course, the larger the traffic transmitted per second, the more cool the Internet, if you use it at home, I personally feel that one trillion is about the same.

20ms is 160m megabit broadband. Here is a list of the relationships between the various units of velocity: 1 byte = 8 bits 1 kb = 1024 bits 1 kb = 1024 bytes 1 mb = 1024 kb It should be noted here that in the way the transmission units are written, b and b represent bytes and bits respectively, and the definitions of the two are different.

Tangerine base. <>Principle:

The traditional ** wire system uses the low-frequency portion of the copper wire (below 4kHz). ADSL uses DMT (Discrete Multi-Audio) technology to divide the original ** line OKHZ to the frequency band into 256 bandwidths.

for the subband. Among them, the frequency band below 4kHz is used for transmission of POTS (traditional ** service).

The frequency band from 20kHz to 138kHz is used to transmit the uplink signal to Wulu, and the band to 138kHz is used to transmit the downlink signal in the band. DMT technology can adjust the number of bits modulated on each channel according to the situation of the line, so as to make full use of the line. In general, the signal-to-noise ratio of a sub-channel. The larger.
