Mac Addresses For Wireless Networking

  

In order to communicate or transfer the data from one computer to another computer we need some address. In Computer Network various types of address are introduced; each works at different layer. Media Access Control Address is a physical address which works at Data Link Layer. In this article, we will discuss about addressing in DLL, which is MAC Address.

MAC Address or media access control address is a unique ID assigned to network interface cards (NICs). It is also known as a physical or hardware address. It identifies the hardware manufacturer and is used for network communication between devices in a network segment. MAC Address usually consists of six groups of two hexadecimal digits. The wireless MAC address for your Echo can be found at the bottom of the Echo Setup screen in the Alexa app. From the Amazon app, visit the Home screen. Choose Settings. Choose My Fire TV or Device.
