ssid broadcast

1. Broadcasting mechanismsStandard broadcast:Standard broadcast (normal broadcasts) is a fully asynchronous broadcast that, after a broadcast, all broadcast receivers receive this broadcast message almost at the same time, so there is no sequence between them, and it cannot

SeeAndroidBroadcast is divided into two different types:Normal broadcast Normal broadcasts) "and" Ordered broadcast Ordered broadcasts)". Normal broadcast is completely asynchronous and can be received by all receivers at the same time logically. The message transmission efficiency is relatively high, but the disadvantage is: the receiver cannot pass the processi

UDP broadcast is divided into three types: All ones-by setting the broadcast address to all ones (255.255.255.255), all hosts on the network receive the broadcast. Network-by setting the broadcast address to a specific network number in the network portion of the IP address and setting all ones in the host portion of

The following blogs record common methods for passing values between different interfaces. This article records the broadcast methods. In the iOS design mode, the notification mode is also one of the important ones,In fact, I think the broadcast mode is more appropriate.It is used to synchronize an object to multiple objects.The usage is very simple. When an object sends a

Security of the broadcastLocal Broadcast:app in-app broadcast (app app is bounded by app app)Broadcasts in Android can communicate across processes and even across apps, and registration is exported the default value is true for intent-filter cases, which can potentially have security implications as follows:1. Other apps may have targeted broadcasts that match the current app Intent-filter, causing the current app to receive broadcasts and process th

Unicast (point-to-point) communication means that a single source node in the network sends packets to a single node. In broadcast communication, the network layer provides services to send packets from one node to all other nodes. Broadcast allows you to send data to each machine on the local subnet. The disadvantage of broadcast is that if multiple processes se

First look at 3 products first: It can be seen that Sina and ESPN architectures are similar (different in news), they are live broadcast and the news level, and then they cove
