Nowadays, wireless technology is widely used, and network functions can be completed as long as wireless technology is available, regardless of whether there are numerous buildings in the podium or in the wilderness. Without the inconvenience of Wired connection, wireless networks play a powerful role. However, the frequency band of the
Multi-point realization of wireless interconnection, can be used a little to many points, relay and other ways to achieve. Different ways of joining can be chosen according to different requirements and different environments. This is only a little bit of a connection to two points.
ABC three dot interconnect. Information Center in a, where AB, ac are visible. We can set a as a central node, B and C to 2 t
Establish communication links between two points (e.g. headquarters and branch offices, network centers and communities). According to customer needs and the actual survey of the situation, there are the following types of transmission:(1) AB two points between visual, no obstruction, no electromagnetic interference, or small interference, AB two points between the distance between the network bridge equipment communication distance requirements.Can u
also greatly increases the speed to several megabytes to dozens of megabytes.
The third is temporary network transmission in some temporary locations. For example, when publicizing the stage results of the Three Gorges Project, the stadium event coverage project only needs to build a temporary network connection by setting up a wireless bridge at the site, so that on-site live broadcasting can be implement

Basic concepts:
1. cut point: if a vertex is deleted and the original connected graph is split into multiple subgraphs, the vertex is calledCut Point.
2. cut Point Set: In an undirected connected graph, if there is a vertex set, after deleting this vertex set and the edge
. The signal scattering from the center to the surrounding area is used. Therefore, an omnidirectional antenna is used in the selection of the antenna to facilitate signal transmission in all directions so that all directions can receive the signal. The antenna that receives wireless signals at the edge must adopt a targeted antenna, which can increase the signal strength to the maximum.

There are two laptops, One Mac and the other Windows 7 at home. Now we need to allow both computers to access each other's files, so we plan to create a point-to-point Wireless LAN.
1. Create a wireless network in the MAC system.
First, enable the airport, that is, enable the wire

Cisco routers play a very important role in the routing industry, and there are also a lot of user groups. It is very important to understand some Cisco router security configurations. Currently, most enterprises and departments connect to the Internet. Generally, a router is connected to an ISP.
This router serves as a bridge between the external Internet and th
Introduction :The definition of trimming and cutting points is limited to the non-direction diagram. We can solve all the cut and cut edges of the non-direction graph by the definition of brute force, but the method is inefficient. Tarjan presents a quick solution to solve all the cutting and cutting edges in the graph through a Dfs.Welcome to discuss, if there are errors please correct meIf you want to reprint, please specify the source http://www.cnblogs.com/nullzx/

[Point connectivity and edge connectivity] In an undirected connected graph, if there is a vertex set, after deleting this vertex set and the edge associated with all vertices in this set, the source image will become multiple connected blocks, this vertex set is calledCut Point Set. ThePoint connectivityIs defined as the number of vertices in the minimum cut point
I. Basic CONCEPTS1. Bridge: is in the undirected diagram of such an edge, if you remove this edge, then the entire undirected graph will be divided into two parts, such an edge is called a bridge undirected graph, if the deletion of an edge, the diagram becomes disconnected, it is called the bridge.2. Cut point: In the
the descendant of U, then y can be connected back to F. In this way, X first goes to F and then from F to Y without passing through U.
In both cases, the connectivity between x and y is not caused.
Similar to the cutover, we can define a bridge without a directed graph: If the undirected graph G is no longer connected after an edge e is deleted, the bridge called E is G. It is not difficult to judge the
Concept
For undirected graph G, the number of connected components that are included in G after the deletion of the vertex V and its connected edge is said to be the joint point (articulation points) or cut point (cut points). Similarly, when you delete an edge E and its connected vertices, the graph contains more connected components, then E is the cut edge or bridge
