Did you know that your monitor, by itself, is a computer? It has its own CPU and its own RAM chips.
Your computer has several other pieces of hardware that are actually mini-computers--they have their own software programs that tell them how to operate, and they are not part of the Windows operating system. And your Windows anti-virus program is often unable to protect them.
IF your computer meets the full requirements of Windows 11, those mini-computers are protected.
