Brief introductionBefore a manufacturer can manufacture a network card, it must register with the IEEE to obtain a vendor code length of 24bit, also known as OUI (Organizationally-unique Identifier). In the process of manufacturing the network card, the manufacturer will burn a 48bit bia (burned-in address, Cure addresses) address to each of the NIC's ROM, the first 3 bytes of the BIA address are the manufacturer's OUI, and the last 3 bytes are determined by the manufacturer itself, but differen
We described the broadcast mechanism of the Android system, in essence, it is a message subscription/advertisement mechanism, so the first step to use such a message-driven model is to subscribe to the message, and for Android applications, the subscription message is actually a register broadcast receiver, This article explores how the Android app will register a broad

The scope of the ANGULARJS has a very hierarchical and nested structure. They all have a major $rootscope (also say the corresponding angular application or ng-app), and all other scopes are inherited from this $rootscope, or nested under the main scope. Most of the time, you'll find that these scopes don't share variables or that they don't inherit anything from another prototype.
So in this case, how do you communicate between scopes? One option is to create a single instance service within t

The IP protocol layer can also use different physical media to transmit IP packets to other IP address hosts. You can add protocol headers to these media sets. For example, the Ethernet protocol layer, PPP protocol layer, or slip protocol layer. Ethernet can be connected to multiple hosts at the same time, and each host has an ethernet ad
