How to change device name connected to WiFi

[Deouss]

After connecting to WiFi network most of my boards show same name 'espressif'
I would like to change it to unique names if possible. What's the way to do that?

Not a hardware question

Thanks - it works great.
Another thing I would like to implement is to make ESP visible on network as device or computer
How do I do that? Is there a structure defining device OS and filesystem etc?
I don't want to use AP mode.
Thanks

Still not a hardware question

Moved to general discussion, because indeed, these aren't hardware questions.
