What is the usual interface used to connect a mobile hard drive or USB flash drive to a computer?
The interface used to connect the mobile hard disk or USB flash drive to the computer is usually "USB". USB is a serial bus standard and a technical specification for input and output interfaces that regulates the connection and communication between computers and external devices. The USB interface has a hot-swappable function and can be connected to a variety of peripherals, such as mice and keyboards.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
The interface used to connect the mobile hard disk or USB flash drive to the computer is usually "USB".
Universal Serial Bus (English: Universal Serial Bus, abbreviation: USB) is a serial bus standard and a technical specification for input and output interfaces. It is widely used in personal computers and mobile phones. equipment and other information and communication products, and expanded to photographic equipment, digital TV (set-top boxes), game consoles and other related fields.
USB is an external bus standard that regulates the connection and communication between computers and external devices. The USB interface has hot-swappable function. The USB interface can connect a variety of peripherals, such as mice and keyboards. USB was jointly launched in 1996 by Intel and other companies at the end of 1994. It has successfully replaced the serial port and parallel port and has become a must-have interface for today's computers and a large number of smart devices.
USB devices mainly have the following advantages:
1. It can be hot-swapped. That is, when using an external device, the user does not need to turn off and on again, but can directly plug in the USB when the computer is working.
2. Easy to carry. Most USB devices are known for being "small, light and thin", which is very convenient for users to carry large amounts of data with them. Of course, USB hard drive is the first choice.
3. Unified standards. Common ones are hard drives with IDE interfaces, serial mouse and keyboards, and parallel port printers and scanners. But with USB, these application peripherals can all be connected to personal computers using the same standards. Then there are USB hard drives, USB Mouse, USB printer, etc.
4. Can connect multiple devices. USB often has multiple interfaces on personal computers, which can connect several devices at the same time. If you connect a USB HUB with four ports, you can connect it again; four USB devices, and so on, you can connect as many times as you want. , connect all your home devices to a personal computer at the same time without any problems (note: can connect to up to 127 devices).

Remote Desktop cannot authenticate the remote computer's identity
Feb 29, 2024 pm 12:30 PM
Windows Remote Desktop Service allows users to access computers remotely, which is very convenient for people who need to work remotely. However, problems can be encountered when users cannot connect to the remote computer or when Remote Desktop cannot authenticate the computer's identity. This may be caused by network connection issues or certificate verification failure. In this case, the user may need to check the network connection, ensure that the remote computer is online, and try to reconnect. Also, ensuring that the remote computer's authentication options are configured correctly is key to resolving the issue. Such problems with Windows Remote Desktop Services can usually be resolved by carefully checking and adjusting settings. Remote Desktop cannot verify the identity of the remote computer due to a time or date difference. Please make sure your calculations

When we assemble the computer, although the installation process is simple, we often encounter problems in the wiring. Often, users mistakenly plug the power supply line of the CPU radiator into the SYS_FAN. Although the fan can rotate, it may not work when the computer is turned on. There will be an F1 error "CPUFanError", which also causes the CPU cooler to be unable to adjust the speed intelligently. Let's share the common knowledge about the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard. Popular science on the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard 1. CPU_FANCPU_FAN is a dedicated interface for the CPU radiator and works at 12V

Solution to NotImplementedError()
Mar 01, 2024 pm 03:10 PM
The reason for the error is in python. The reason why NotImplementedError() is thrown in Tornado may be because an abstract method or interface is not implemented. These methods or interfaces are declared in the parent class but not implemented in the child class. Subclasses need to implement these methods or interfaces to work properly. How to solve this problem is to implement the abstract method or interface declared by the parent class in the child class. If you are using a class to inherit from another class and you see this error, you should implement all the abstract methods declared in the parent class in the child class. If you are using an interface and you see this error, you should implement all methods declared in the interface in the class that implements the interface. If you are not sure which
