In wireless networking, SSID stands for which term?

• A. Secure System Identification
• B. Service Set Identifier
• C. Network ID
• D. System Security Identifier

Answer: (C)

SSID is the name of a wireless network, and it expands to Service Set Identifier. In IEEE 802.11, networks are identified by this name so devices can find and connect to the correct network. The SSID is carried in management frames like beacons and probe responses, helping clients discover networks and enabling roaming when multiple access points share the same name. It isn’t a security feature; hiding the SSID only hides the name, not the network itself. The other terms listed aren’t the standard WLAN terminology—Network ID is more of an IP-layer concept, and the remaining options aren’t used in 802.11 to describe this identifier.
