Final answer:
The group of related nodes connected to a wireless Access Point is known as a Basic Service Set (BSS), which is identified by a unique SSID.
Step-by-step explanation:
The group of related nodes associated with a wireless Access Point (AP) is called a Basic Service Set (BSS). In a wireless local area network (WLAN), each BSS consists of multiple devices that are connected to the same AP and can communicate with each other. The AP serves as the central transmitter and receiver for network traffic.
Each BSS has a unique identifier known as the Service Set Identifier (SSID), which is a case-sensitive, alphanumerical name that distinguishes one network from another.
