ssid broadcast

I. Communication modes are classified in IPv4 networks. There are three communication modes available for the host: 1. unicast: data communication between a single host and a single host 2. Broadcast: A single host sends data packets to all hosts in the network. 3. Multicast: A single host sends data packets to a selected group of hosts for different unicast, broadcast, and multicast purposes, and uses diff

Network interconnection devices can divide networks into different conflicting and broadcast domains. However, different network interconnection devices may work at different layers of the OSI model. Therefore, the effect of dividing conflicting domains and broadcast domains is also different. For example, a repeater works on the physical layer, a bridge and a switch work on the data link layer, a router wo

The three terms unicast, multicast, and broadcast unicast (Unicast), multicast (multicast), and broadcast (broadcast) are terms used to describe how network nodes communicate with each other. So what do these terms mean? What's the difference?1. Unicast:Communication between network nodes is like a conversation between people. If a person speaks to another person

The socket broadcast packet is often used for mutual discovery and messaging between two devices within the LAN, and is often encountered during Android application development, such as between two Android devices, smart hardware such as Android and the bracelet, Between Android and Windows computer and so on.This article focuses on programming considerations and workarounds for developing broadcast package

1, Life cycleIn the official Android documentation, we recommend that we do registerreceiver in Onresume, Unregisterreceiver in OnPause, and the reasons they give are: If Registering a receiver in your activity.onresume () implementation, you should unregister it in Activity.on Pause (). (You won ' t receive intents when paused, and this would cut down on unnecessary system overhead). Do is unregister in activity.onsaveinstancestate (), because this won ' t is called if the user moves back in th

First, the concept of understanding:1. Conflict domain (physical segmentation):A collection of all workstations connected on the same wire, or a collection of all nodes on the same physical network segment, or a collection of nodes competing for the same bandwidth on the Ethernet. This field represents the area in which the conflict occurs and propagates, and this area can be considered a shared segment. In the OSI model, conflict domains are considered the first layer of concepts, and devices t

Each application in Android can register its own broadcasts of interest so that the program will only receive the broadcast content that it cares about, either from the system or from other applications. Android provides a complete set of APIs that allow applications to freely send and receive broadcasts. Sending a broadcast is the use of a previously known intent, and a

We just have to register a broadcast receiver, the equivalent of buying a radio, we can receive these special events.These events, when they happen, always

Features: 1. Data Transmission is not connected, so it is not reliable (in line with the characteristics of UDP) 2. Data Transmission is intended for the entire subnet. Any computer in the subnet can receive the same data; 3. Broadcast is used for UDP and the original IP address, and cannot be used for TCP Purpose: 1. Locate the host in the local subnet The premise is that the host is known to be located in the local subnet, but does not know its Uni
