A bridge is a hardware device used to interconnect two or more data link layers (the second layer of the OSI seven-tier model) so that network devices on different network segments can access each other. When you want to interconnect multiple virtual machines or Ethernet interfaces in a host, you need to have a bridge-like concept in a Linux host. A soft bridge i
The bridge mode is a very useful and complex mode. Familiarity with this mode is helpful for understanding the object-oriented design principles, including the "open-closed" principle (OCP) and the combination/aggregation Reuse Principle (CARP. Understanding these two principles helps to form correct design ideas and cultivate a good design style.
Note: In the book "Java and mode", the Bridge mode is not a

It is an important part of the Motherboard chipset. Generally, it is located at the far bottom of the motherboard from the CPU slot, near the PCI slot. This layout takes into account the many I/O buses it connects, A little farther away from the processor is conducive to wiring. Compared with the North Bridge Chip, the data proces

1. Bridge mode is very similar to strategy mode(in fact, a lot of design patterns are similar, because all the models are designed according to design principles , the principle of design is equivalent to the heart of martial arts, design mode is a move, as long as the heart is perfect, you can no recruit win a recruit .) )There is also a more detailed description of the strategy mode VS.

Build a bridge between PHP and Java and use this bridge to build a communication channel between the two entities, with the help of this bridge, you can develop classes in Java , and then in PHP In the same way that you can use PHP scripts in your Java desktop or Web application.http://php-java-bridge.sourceforge.net/pjb/ is the official website for PHP Java
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 wireless network is not the only one. How can we connect different wireless networks? This requires the help of a wireless

Overview
In software systems, some types of software systems have two or more dimensional changes due to their own logic. How can we deal with such "multi-dimensional changes "? How can we use object-oriented technology to make this type easily change in multiple directions without introducing additional complexity? This requires the Bridge mode.

I felt that this competition was not ideal. Maybe it was a bit anxious to enter the competition. After checking the information, I got my seat and was not prepared yet. Then I opened the browser and entered the website, at that time, I felt bored in the room. I was bored and didn't calm down. I didn't
Bridge is one of the complex and hard-to-understand modes in the design model, and is also one of the frequently used modes in OO development and design. The combination of abstraction and implementation is completely decoupled. The advantage is that abstraction and implementation can be changed independently, and the coupling of the system is also greatly reduced.
