Currently, many organizations have built internal lan. Most enterprise networks use twisted pair wires to connect to NICs for communication. Among them, twisted pair wires generally use 5 types of lines with a transmission rate of 100 MB. There are some differences between NICs. Many NICs adopt 10 Mbps/mbmps adaptive NICs, that is, the transmission rate automatic
Now many units have been built intranet, the general enterprise network is mostly using twisted-pair to connect the network card mode to communicate. The twisted-pair wires are usually 5 lines, and the transmission rate is 100MB. and the network card is a certain difference, many network cards are taken 10mbps/100mbmps Adaptive network card, that is, the transmission
+ is high (UP) and D-is low (down ), the bus sends an idle signal at full speed, indicating that the device is suspended.
5. Conclusion
This article analyzes the features of the high-speed transmission environment of the USB2.0 interface and the working principle of the 8-bit phy in this mode. To ensure that USB2.0 wo
wired network, and the conversion is followed by the data.
We have already discovered that the two speed standards of 802.11n both exceed Mbps of wired network, so which is faster?
With questions, let's break down them one by one.
The following data is taken from the Internet and tested in a single Pair and encrypted environment.
First, let's take a look at the performance of 802.11b.
The theoretical maximum spe
Many units and companies set up their own local area network, but a newly built small LAN, a server, more than 10 workstations, using a switch as an access device, connecting lines to 6 types of lines. The main fault performance for the network in the computer transmission speed is slow, any one station on the server to copy a 100MB file, it should be 30 minutes. Even the adjacent two workstations are so sl
Is it usb3.0 to see the speed of the gods of others? Have you complained about the speed of your USB2.0? In fact usb2.0 the theoretical speed is 60mb/s, but most cases usb2.0 the highest actual transmission speed only 30mb/s, That is because USB2.0 uses the serial
Electronics and Computer Engineering and TOEC, Daniel Brumenthaler, says faster Ethernet can solve the problem of Internet data congestion and support large-scale applications such as cloud computing.
Stutt Alby, the Verizon Vice-President for network architecture, says TOEC's ongoing research and development efforts will make the future of the internet possible.

Comparable to optical fiber! Wi-Fi transmission speed up to 100 Gbps
What is the maximum transmission rate of current WiFi? Is the 11ac technical standard three-frequency 5300 Mbps? Or 11ad 7 Gbps? Or 11ax's 10 Gbps? The answer is 100 Gbps! Yes, this is comparable to the optical fiber transmission

The small new Air12 standard USB2.0 interface and a standard USB3.0 interface, so what is his measured data? Let's take a test.
Equipment: Small New Air12 one, SanDisk USB3.0 u disk One, the King USB3.0 mobile hard drive A
Transfer file: A Win10 mirrored file for a single file of 4G degrees
Solution:
1, USB3.0 mobile hard disk using Air12 USB2.0 interface to transfer large files, measured speed stability in 37mb/se
A while ago, Baidu online storage provided a free GB space application. At that time, I was curious, and I often reported an error due to the use of Bt on my mobile disk, I would like to take this opportunity to upload files to Baidu for temporary storage, free up space to sort out the mobile hard disk, and I also created an account. 100 GB, plus the original 5 GB, a total of GB to hand, just today there is time, we are ready to copy the mobile hard d
More and more people are using wireless networks to watch movies and video chats. The limitations of wireless networks are shown. The transmission speed in wireless networks is greatly affected, especially video files, this article focuses more on speed and introduces how to improve the speed of wireless video
This article describes in detail the transmission speed problems in LAN faults, provides possible analysis of some faults, and provides troubleshooting methods, the following article gives you a detailed answer.
A just-built small LAN, a server, and more than a dozen workstations, using a switch as the access device, the connection line is 6 types of lines. The main failure is that the
location, do not be alarmed. You can use a targeted antenna (as we will mention in the next serialization article ), or extend your DSL and cable lines.
If you select the latter, you will find that it is a laborious and costly project to build a line through the wall so that your router can be placed in the correct place, and it will cause damage. As another option, you can consider using a thin coaxial or ethernet cable, which is wrapped in tape and can easily be inserted into walls. After you
Many people are concerned about Wi-Fi wireless transmission speed, in addition to the hardware itself adjustment, placement is also a very important factor. With some very basic techniques (how to place routers and how to configure them) and some of the more sophisticated techniques (with dedicated equipment, etc.), you can carve out a new world for your wireless router. After spending several hours optimiz
Failure analysis is tied to the following possibilities:
1. Hacker attack or Medium worm virus
2. Line fault
3. Switch overload
4. Network adapter failure
5. Connectivity issues
Troubleshooting methods:
1. Select a few workstations, check its network configuration, correct. Can ping the server, response time
2. In the elimination of line failures, we know that all computers appear in the network computer
