SSID: (Service Set Identifier): is the primary name associated with an 802.11wireless local area network (WLAN) including home networks and public hotspots. Client devices use this name to identify and join wireless networks.

MAC Address: A MAC address is given to a network adapter when it is manufactured. It is hardwired or hard-coded onto your computer's network interface card (NIC) and is unique to it.

IP Address: An IP address is a address consists of four numbers, each of which contains one to three digits, with a single dot (.) separating each number.IP Address's designed to allow one computer (or other digital device) to communicate with another via the Internet. IP addresses allow the location of literally billions of digital devices that are connected to the Internet to be pinpointed and differentiated from other devices

Signal Strength (dBm): The most accurate way to express it is with dBm, which stands for decibels relative to a milliwatt. RSSI (Received Signal Strength Indicator) is a common measurement as well, but most WiFi adapters handle it differently, so it's common for applications to convert it to dBm.
The first thing to understand about dBm is that we're working in negatives. -30 is a higher signal than -80, because -80 is a much lower number.
