Which abbreviation stands for Service Set Identifier?

• A. SSL
• B. SID
• C. SSID
• D. SMTP

Answer: (C)

Wireless networks are identified by a name that appears when you scan for connections. This name is the Service Set Identifier, abbreviated SSID, and it serves as the network’s label that devices use to join the correct Wi‑Fi network. Access points broadcast the SSID so clients can discover networks and select the one they want to connect to. Some networks can be configured to hide the SSID, but the identifier itself remains the label for that network. By contrast, SSL is a web traffic encryption term, SID is used in other contexts like security identifiers or session IDs, and SMTP is the email transfer protocol. So the abbreviation for Service Set Identifier is SSID.
