For ISDN (Integrated Services Digital Network), the hardware required typically includes an ISDN terminal adapter or an ISDN modem, which connects to the user's device and the ISDN line. On the software side, users may need drivers or configuration software to manage the connection. In contrast, ADSL (Asymmetric Digital Subscriber Line) requires an ADSL modem or router to connect to the telephone line, and it usually includes built-in software for configuration and management. Additionally, users may need a compatible computer or device with an Ethernet port to connect to the ADSL modem.

The MAC address (Media Access Control) is used to identify a specific piece of network hardware, such as a network interface card (NIC), a router or a modem. Since your ISP will only wish to allow Internet access to paying customers, it can check the MAC address of your router against its list to see if it belongs to a valid customer. If you change your equipment, typically, your ISP will provide you with a process to register the new hardware's MAC address with them.
Yes. The term WiFi generally refers to the internet connection from the actual computer/laptop or internet device like a smart phone to a wireless router somewhere near-by. That wireless router is connected to the ISP (Internet Service Provider). The connection there can be any type of internet connection. Dial-up, ISDN, DSL, Cable Modem, or FiOS.
