== Synchronization  == 

 Hello, I'm Vertium. I noticed that you recently removed some content from Synchronization (alternating current) without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; I restored the removed content. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! Vertium When all is said and done  

  
 Hi! The information appeared duplicated on my browser after multiple refreshes, but the current page looks okay. I guess it was a technical issue. Sorry for the inconvenience. I don't edit wiki often, so please let me know if I'm in error. Thank you.
