How Windows XP protects personal document privacy
Windows XP has an advanced intelligent function, that is, it can record the files you have accessed. This function provides convenience for users to open the file again, if you are concerned about security and performance-this function should be blocked. We can meet the requirements through the following settings:
In the "Group Policy" window, expand "User Configuration" → "Administrative Templates" → "Taskbar and 'Start' Menu", and then in the right window, "Do not keep the record of recently opened documents" and "Clear recently opened when exiting" "Documentation" two policies can be enabled.
The low-voltage transformer mainly uses the principle of electromagnetic induction to change the AC voltage. Its main functions are voltage conversion, current conversion, impedance conversion, isolation, and voltage stabilization. The low voltage transformer is the transformer below 600V. Low-voltage transformer is composed of three parts: primary coil, secondary coil and iron core (magnetic core). It is usually used in electrical equipment and wireless circuits as a tool for raising and lowering voltage, matching impedance, and safety isolation.
Classification of low-voltage transformers
1. According to the number of phases, it can be divided into single-phase transformer and three-phase transformer.2. According to the purpose, it is divided into control transformer, local lighting transformer, isolation transformer, rectification transformer, etc.
3. According to the coil winding method, it can be divided into foil winding, wire winding, etc.
4. According to the protection mode, it can be divided into: with enclosure, without enclosure, etc.
