What is an SSID?

An SSID, or Service Set Identifier, serves as a unique name assigned to a wireless network. When devices connect to Wi-Fi, they rely on the SSID to distinguish between different networks available in the vicinity. This identification is essential because multiple wireless networks might be present in a given area, such as a home with various devices or a public space like a café with guest access.

The SSID can be broadcasted or hidden; when broadcasted, it allows devices to scan for and display available networks, making it easier for users to connect. If hidden, users need to know the exact SSID to connect manually. Understanding SSIDs is crucial for managing and securing wireless networks, as it aids in identifying which network to join and helps with troubleshooting connectivity issues.
