SSID is the short form for Service Set identifier and is a term used in networking to represent the name of a network. The SSID for any network is in a human-readable format by using simple languages with characters and numbers in it.
A common example of SSID is the name of WiFi that is available on turning on WiFi on your smartphone or laptop etc. All the names of available WiFi networks are the SSIDs and they are written in simple language. Every network has an SSID that represents the network to others that want to connect to the WiFi.
The name of hotspots that we use are SSIDs and these are editable so the host can change it any time. Only the host or administrator of the network has access to changing it manually and every such network has a name even if not set manually.
The SSID for available WiFi that is using default SSIDs is usually the model name of devices such as router or smartphone. SSID also involves the security of WiFi and experts recommend manual SSIDs rather than the default SSID. The manufacturer gives hardware or product name as default SSID for the time when it is used for networking.
Every time you turn in your WiFi you see all the SSIDs of available WiFi networks that are within your device’s range. To connect to these SSIDs you either need a password if it’s password-protected or you can simply just select the SSID and connect to it.
SSIDs are case-sensitive and using a capital letter makes a whole lot different when used. For a wireless network, the host can also have more than one SSID that represents the WiFi network to others. For more control, SSIDs can also be ghosted to hide the SSID from users so the network isn’t available to others.
