As an electronic part matching usb, USB base has a wide range of applications, and its speed is also relatively fast, which is a series of requirements for us to understand in the process of each usb. Because in many cases, the performance of USB mothers can attract our attention more.
There are many kinds of USB mothers, but their different types have different characteristics. Today we will briefly describe the characteristics of the next type of USB mothers in the use process, and whether their characteristics are the same or different with those of other USB mothers. The following aspects are the embodiment of the usage characteristics of A-type USB base. I hope that the short content can be helpful to everyone.
1. Faster speed
Speed function is one of the most important features of type a USB technology. The maximum transmission rate of USB interface can reach 12 Mb per second, which is 100 times faster than serial port and 10 times faster than parallel port.
2. Supporting Multimedia
Type a USB provides two-way data support for the telephone. USB can support asynchronous and isochronous data transmission, enabling the telephone to integrate with PC, share voice mail and other features. USB also has high fidelity audio. because the USB audio information is generated outside the computer, it reduces the time when electronic noise interferes with the sound quality, so that the audio system has a higher fidelity.
3. Flexibility of connectivity
Because the USB interface supports multiple serial connections of different devices, a USB interface can normally connect 127 USB devices.
4. Easy to use
We can connect many different devices when using USB interface. However, in the past, parallel and serial ports could only connect one device, so we had to shut down when switching from one device to another. USB saved users these unnecessary troubles. besides connecting multiple devices in series, USB also supports hot swap function.
In the application of software, the application software and driver program designed by USB can start automatically without users doing more operations.
5. Independent power supply
Generally, devices using parallel and serial ports need to have their own power supply system, but USB devices do not need, because type a USB interface provides built-in power supply. Therefore, type a USB power supply can supply 5 volts of power to low voltage equipment, so the new equipment does not need special AC power supply, which reduces the cost of these equipment and improves the cost performance ratio.
The above five aspects of the characteristics of A-type USB mothers, I hope that you can read A-type USB plug-in to have a better understanding, although the USB mothers have some similarities in many aspects, but careful observation and analysis is different, so that careful analysis of these characteristics can be of great help to our work and learning, I hope you can read and use them carefully.
The USB motherhood will have these advantages when it is used, which reflects that understanding is helpful for later use, and we hope that you will pay attention to our website for a long time.
