Hello. This is a message to let you know that one or more of your recent contributions, such as the edit(s) you made to Data communication, did not appear to be constructive and have been reverted. Please take some time to familiarise yourself with our policies and guidelines. You can find information about these at our welcome page which also provides further information about contributing constructively to this encyclopedia. If you only meant to make test edits, please use the sandbox for that. If you think I made a mistake, or if you have any questions, you may leave a message on my talk page. Thank you.

Please refrain from making unconstructive edits to Wikipedia, as you did at Serial communication. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Repeated vandalism may result in the loss of editing privileges. Thank you. WhichUser AmI  15:09, 19 May 2023 (UTC)

You may be blocked from editing without further warning the next time you vandalize Wikipedia, as you did at several pages. WhichUser AmI  15:15, 19 May 2023 (UTC)

This is your only warning; if you vandalize Wikipedia again, as you did at Address Resolution Protocol, you may be blocked from editing without further notice. WhichUser AmI  15:17, 19 May 2023 (UTC)
