One, the Observer pattern definitionIn the Observer pattern, an observer manages the observer object that relies on it, and it defines a one-to-many dependency, so that when an object changes state, all its dependents are notified and updated automatically.The subject (The observer) updates the observer through a common interface, and the observer relies on this topic.II. Observer Model example--meteorological monitoring systemDescribe:The meteorological monitoring system is divided into three p

Question:On a dark, stormy night, the roof and doors of farmer John's cowshed were blown away. Fortunately, many cows are on vacation, so the cowshed is not full. The cowshed is lined up next to the other, and the ox stays in the room for the night. Some cowshed have cows, and some do not. All cowshed have the same width. Farmer John had to erect a new plank before the cowshed as soon as possible after the door was lost. His new timber supplier will supply him any length he wants, but the stingy

Article Title: Embedded System BootLoader technology insider. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. 　　 1. Introduction Running GNU/Linux systems on dedicated embedded boards has become increasingly popular. An embedded Linux system can be divided into four levels from the software perspective: 　　 1. boot

FTP enables users to transfer files between two networked computers, which is the primary way to deliver files on the Internet. With Anonymous (Anonymous) FTP, users have free access to Internet-rich resources. In addition, FTP also provides login, directory query, file operation and other session control functi

motherboards also support these two kinds of interfaces. The Pci-e interface is used only for desktops. Solid state hard Disk interface type The current SSD mainstream interface, or the SATA3 (6Gbps) interface, their number is very much, is also the most common. The mSATA interface is also a common SSD interface that uses SSD for mSATA interfaces, mostly for laptops, but a few desktop boards also suppo

that it can help users Reduce network costs from the ports of each module. The disadvantage is that the port efficiency of network data is relatively low, all data exchange relies on the data processing board capability of the core board. As the number of boards increases, the performance of the entire enterprise-level Core switch decreases, that is, the number of ports in the chassis is inversely proportional to the performance. In addition, the lat

The Optical Fiber Channel consists of FDDI multi-mode optical fiber cables, wiring boards, workstation sockets, and connection wires at both ends. 1.

data bus connecting multiple boards may also become a bottleneck, all of this makes it difficult to greatly improve the forwarding performance of traditional routers. At the same time, the network scale is further increased, and more ports need to be supported by the vro. However, generally, the vro only supports 10 ports, and even a large vro only supports 50 ports. These shortcomings will cause the router to become the bottleneck of the network and

Problem description: In a checkerboard consisting of 2 k × 2 k squares, a square is different from other squares. It is called a special square and a special checkerboard. In the Board coverage problem, we need to use four different types of L-shaped bone cards in the figure to cover all squares except the special square on the given special board, And no two L-type dominoes can overlap. Analysis: When k> 0, the 2 k × 2 k board is divided into 4 2k-1 × 2 k-1 sub-board (.The special check box

capability of the core board. As the number of boards increases, the performance of the entire switch decreases, that is, the number of ports in the chassis is inversely proportional to the performance. In addition, the latest distributed switching architecture can be adopted. On each interface card, the local machine processes all data exchange, routing, forwarding, and security filtering, multiple boards

coverage schemes for the former n–2 lattice. Therefore, if f (n) is used to represent the number of coverage schemes for a 1xn checkerboard, then there is exactly f (n) = f (n–1) + f (n–2). In addition, since f (1) = 1, f (2) = 2, thus the next number F (3), F (4), F (5), ... It just happens to form the Fibonacci series. in this way, then use the Bricks cover two independent 1xn chessboard, the total scheme number is Fn+1 F . We intentionally put the two independent

request broadcast packet, all routers or servers extract the server information from the packet. If the packet is directed to their own, the backend ack (similarly, because different ack methods on the vro may be broadcast packets or unicast packets), other servers or vrouters will not return ack. This is the ACK stage.========================================================== ================================== Question 1:When I debug the board, I encountered this situation: I have two
