SSID
termnetworking
Stands for: Service Set Identifier
The name a wireless network advertises - a label, not an identity, and trivially copied.
Because the name is only a string, any device can claim it, which is the whole basis of the evil twin: a stronger radio announcing the same network and collecting whatever connects. Hiding it protects nothing, since clients that know it broadcast their search for it and reveal it anyway. What actually distinguishes a legitimate network is the credential exchange behind the name, which is why enterprise authentication and certificate validation on the client are the controls that matter.
Also known as: Service Set Identifier, network name
