What is the purpose of a Service Set Identifier (SSID) in a WLAN?

• A. To manage bandwidth
• B. To uniquely identify a wireless network
• C. To encrypt communications
• D. To enhance connection speed

Answer: (B)

The purpose of a Service Set Identifier (SSID) in a Wireless Local Area Network (WLAN) is to uniquely identify a wireless network. This identifier is essentially the name that is assigned to the network, allowing devices to distinguish one network from another when they are searching for available connections. The SSID helps users and devices select the appropriate network to connect to, especially in environments where multiple wireless networks exist. Having a unique SSID is crucial because it prevents confusion among users and devices, ensuring they connect to the intended network rather than an unintended one. This is particularly important in public or densely populated areas where multiple WLANs may overlap. While the SSID itself does not provide any security or encryption, it plays a key role in managing how devices connect to the network. Managing bandwidth, encrypting communications, and enhancing connection speed are all important aspects of WLAN functionality, but they do not encompass the primary role of the SSID. The SSID specifically pertains to network identification.
