What is the difference between network speed and traffic, and what is the difference between traffic

Speed. It is the speed of your Internet access, and the traffic refers to your bandwidth, which is the size of your Internet channel. Just like the highway is a truth, the network speed is the speed on the road, and the traffic is the number of lanes you drive on the road. You're walking on the highway level.

The higher the relative to your speed, the faster you may be, of course, your car --- is your computer, not a tractor, if you are a construction truck pulling earth.

Walking on the high-grade highway with unlimited speed, you can know what it feels like to pull the wind just by thinking about it. I don't know if I understand my explanation.

1M bandwidth refers to the highest uplink 512k and the highest downlink 1024k, the connection speed only refers to the real-time speed of your connection to a certain server, **related to the **server you choose**, if the connection speed is fast** speed is of course the best. So the internet speed you test is just the speed you connect to the test server, and it has nothing to do with **.

It has been said above, and 1m is the theoretical upper limit, which can never be reached in practice. For example, BT is theoretically only limited by your network speed, but even if the resource speed is fast enough, you can't reach the upper limit of 1M.

The calculation units of Internet traffic are mainly MB and KB, and the conversion rules between units are: 1MB=1024KB, 1KB=1024B, 1B (bytes) = 8bits (bits).

The unit of calculation of Internet speed is "megabits per second (Mbps)", which means that 1Mbps means that the network speed is "1 megabit per second", not "1 megabyte per second".

For example, if a 42MB is small, the 3G network speed is 42MBPS and 21MBPS, it will theoretically take 8 seconds or 16 seconds, not 1 second or 2 seconds, and the actual speed may be slightly lower due to network and other factors.

Traffic is wireless (except wifi), broadband is wired or wireless broadband (network card), to be precise, traffic is a business statement, broadband is a technical standard. The two cannot be compared.

For operators, the broadband revenue belongs to the marketing department, and the marketing department is in charge of traffic (landline mobile phones) and broadband and inter-network settlement, which is counted as basic service income; Traffic revenue belongs to the value-added business department, that is, the revenue other than mobile phone traffic.

I used to be the business director of the value-added center, which was divided into fixed network value-added and mobile value-added. Both have hundreds of income segments.

First, the technology is different.

1. Traffic: Internet access through GPRS, EDGE, TD-SCDMA, HSDPA, LTE and other mobile communication technologies.

Second, the speed is different.

1. Traffic: 4G communication technology allows users to access the Internet more quickly, and the speed can be as high as 100M per second.

2. WiFi: The speed of wifi depends on the local broadband level. The speed can be higher than 100m per second.

Third, the content is different.

1. Traffic: Stuffy eggplant is a mapping technology, first of all, the sending device will send the information to the wireless carrier antenna, and the antenna will quickly compile it after receiving the information, and compile the compiled data into digital signals, which will be sent to different mapping areas.

2. WiFi: It is a kind of commercial Ant Interception Certification, and it is also a wireless networking technology, which used to be connected to the computer through network cables, and Wi-Fi is connected to the network through radio waves; A common one is a wireless router.

Mass flow rate (kg h) can be converted to flow velocity (m s), flow rate = flow rate pipe inner diameter pipe inner diameter 4. But it is necessary to know the cross-sectional area of the flow channel, the density of the liquid.

The flow rate is proportional to the pipe section and flow velocity, and the relationship between the three is Q=SV

where q — flow rate (m3 h);

s — cross-sectional area (m2); Rough whoops.

v — average velocity of the fluid (m s).

Or after splitting the s, it becomes: q = (d2) 4 * v * 3600 (m3 h).

where q — flow rate (m3 h);

d — inner diameter of pipe (m);

v — average velocity of the fluid (m s).

The relationship between mass flow and volume flow is: qm= q

where — density of the liquid (kg m3, t m3); Yan Dan line.

Clear water at room temperature — 1000kg m3.

The relationship between mass flow rate and flow velocity can be obtained: qm= (d2) 4 * v *3600 (m3 h).

Note: The volume flow rate is expressed in Q and the units are: m3 s, m3 h, l s, etc. The mass flow rate is expressed in qm and the units are: t h, kg s, etc.

<>Pipe Diameter:It means that when the pipe wall is relatively thin, the outer diameter of the pipe is almost the same as the inner diameter of the pipe, so the average value of the outer diameter of the pipe and the inner diameter of the pipe is taken.

It is called as a pipe diameter. It usually refers to the general synthetic material or metal pipe, and the average of the inner diameter and outer diameter is taken as the pipe diameter when the inner diameter is large.

Flow rate:（flow velocity；current velocity) displacement of the liquid per unit of time. The flow rate of the particle is a vector that describes the direction of movement and the speed of movement of the fluid touch circular body point in a certain smile.

Its direction is tangent to the trajectory of the particle.

The direction is consistent. Its size is: u=lim< t 0> s t=ds dt. The unit is m s, and s is the distance that the liquid particle flows in t time.

Traffic:It refers to the amount of fluid flowing through the effective section of a closed pipeline or open channel per unit time, also known as instantaneous cavity flow. When the amount of fluid is expressed in volume, it is called volumetric flow; When the amount of fluid is expressed in mass, it is called mass flow.

The volume of fluid flowing through a certain section of pipe per unit of time is called the volumetric flow rate of that cross-section. It is referred to as flow and is represented by q.
