What does SSID stand for?

• A. Secure Sockets Layer
• B. Service Set Identifier
• C. Simple Server Identification
• D. System Serial ID

Answer: (B)

SSID stands for Service Set Identifier. It is the name of a wireless network that a Wi‑Fi access point broadcasts so devices can identify and connect to the correct network. When you scan for networks, you see a list of SSIDs; selecting the one you want lets your device join that specific network and, if needed, enter the credentials. The SSID helps distinguish one network from another, which is especially important in areas with multiple APs or overlapping networks for roaming. Note that hiding the SSID doesn’t provide real security; it only makes the network less visible, while the actual protection comes from proper encryption and authentication.
