(I’ll talk about that “should” more in a moment.) You can see your network adapter’s MAC addresses by using the command prompt in Windows Each network adapter on your computer, including wired and wireless interfaces, has one. MAC addresses are typically used only to direct packets from one device to the next as data travels on a network. That means that your computer’s network adapter’s MAC address travels the network only until the next device along the way. If you have a router, then your machine’s MAC address will go no further than that. The MAC address of your router’s internet connection will show up in packets sent further upstream, until that too is replaced by the MAC address of the next device – likely either your modem or your ISP’s router.

     1.Formulation: Bluetooth Technology’s invention has been credited to Ericsson which in the year 1994 launched it as a wireless communication alternative to RS232. Wi-Fi, though had researches since the mid 80s, was officially launched in the year 1997. A committee for development of Wi-Fi was set in the year 1990 which was head by, Victor Hayes who is also known as father of Wi-Fi.          2. IEEE Standards: Bluetooth was initially defined under IEEE 802.15.1 standard but is now taken care by a Special Interest Group (SIG). Wi-Fi, on the other hand, is defined under 802.11.x (x=a, b, c, and so on) series of protocols and is currently maintained under the same. A Wi-Fi alliance founded by various companies tests and authorizes gadgets to be Wi-Fi compatible.          3. Versions: Since its inception, Bluetooth has seen several versions of it such as Bluetooth 2.0, Bluetoo...
