again ... I am also free to enter one of the most creative periods in my life. "2005"There are a lot of things that inspire my creativity, but sometimes it's hard to see what's right in front of you. For example, Jobs said:In the last few years of next, I really understood two things that I saw in the 1976 Xerox Parker Research Center: One of course the plane interaction, and the other, the sophisticated personal computer network I'm now talking abou

Secret: 58 essential knowledge points of switched Ethernet. you can master the following knowledge points of switched Ethernet in just a few minutes. Welcome to the vswitch world. The local connection will also be mentioned in this article. ◆ Ethernet was originally based on coaxial cable. In, Xerox \ inter and DEC proposed DIX. ◆ In, the standard was proposed. ◆ CSMA/CD communication process, transmission-listener-interference-random wait-transmissio

The next generation network includes a variety of changes in the way networks are being built. It uses a large number of innovative technologies to provide a comprehensive and open network architecture, including voice, data, multimedia, and other services, however, the development path is also full of "growth troubles ". The United States has a majority of IPv4 address resources, followed by Europe. The remaining countries only have a small number of IP resources. MIT,

Unknown stories of Apple and Google Microsoft, but not of Google Microsoft Summary: Why are the two dominant players in the smart phone field always fighting against each other? Why is there such a remark about Android in Steve Jobs' biography: "If necessary, I will use my last breath to spend $40 billion of Apple's savings and destroy Android, because it is a stolen product "? The Windows operating interface of the Apple system is priorMicrosoftAfter Microsoft saw Apple's windows operating sys

Originally did not want to jump out of the big head garlic, but recently found in the garden on the MVC article and discussion of the wind more and more fierce, which hasSome of my friends ' views are not what I admire and recommend, but I have also been busy doing the MVC "literacy work" for my colleagues in the company.So we collected a number of people in the process of exposure to MVC often appeared to do a little explanation, I hope to communicate with you more,Oh.Of course, some of the pro

What is MVC. What is MVC? I remember the first interview with phper (php is another web development language that can be quickly used for me). people asked me about MVC. I only know that m is model and v is view, c is Controller. what is MVC?

allow incoming echo requests. IGMP Protocol (Internet Group Management ProtocolInternet Group Management Protocol). This protocol runs between the host and the multicast router directly connected to the host. It is a protocol used by the IP host to report the identities of multicast Group members. Through the IGMP protocol, on the one hand, you can use the IGMP protocol host to notify the local router to join and receive information about a specific multicast group. On the other hand, the route

frame is discarded when the target station receives a data frame with an error and does nothing else. the correction of errors is determined by the top management. if some data is lost and retransmitted at the higher level, Ethernet does not know that this is a re-transmitted frame, but is sent as a new data frame.

The RIP Protocol is a type of routing protocol. It has been applied in many places. For the network architecture, the routing information protocol (RIP) is an internal mechanism in our network, mainly for managing network management and routing. The RIP Protocol is also required for data distribution and transmission between different protocols. Now we have come to understand every aspect of this agreement in detail. I. background The route information protocol (RIP) uses the number of hops as t

Next we will parse the content of the route information protocol RIP. For some of the content of this protocol, we will mainly explain the background of this Protocol, as well as the contents related to the route update metric, stability, and timer. I hope this will help you. I. background The route information protocol (RIP) uses the number of hops as the distance vector protocol of metric. RIP is widely used in global Internet routing. It is an internal gateway protocol that implements routing

The SPX Protocol is based on Xerox SPPSequences Packet Protocol, it is also a network protocol for LAN developed by Novell. In the LAN, the SPX protocol is mainly responsible for error-free processing of the entire transmitted data, that is, error correction. Application: the SPX protocol is generally u

the value used to select a path when the router forwards the route to the next vro in the forward packet to the next vro in the network. The common distance vector routing selection protocols include: Route Selection Information Protocol (RIP) is a distance vector routing protocol first implemented in Xerox Network System (XNS) and then implemented in Novell's NetWare) is the distance vector routing protocol developed by Cisco. The route selection ta

different representations. For example, a batch of statistical data can be represented by histogram, pie chart. C exists to ensure the synchronization of M and V, and once M is changed, V should be updated synchronously.[1-2]Model-View-Controller (MVC) is a software design pattern invented by Xerox PARC in the the 1980s for programming language Smalltalk-80, which has been widely used. It was later recommended as a design model for Oracle's Sun Compa

M is the exponential data model, V is the user interface, and C is the controller. The purpose of using MVC is to separate the implementation code of M and V, so that the same program can use different expressions. For example, you can use a column chart or pie chart to represent a batch of statistical data. The purpose of C is to ensure synchronization between M and V. Once M changes, V should be updated synchronously. Model-View-controller MVC) is a software design model invented by

concept that does not set the implementation of a specific language. It can overcome the disadvantages of a single inheritance feature language (such as Java). Currently, the specific implementation of AOP has the following items: AspectJ (TM): it was created in Xerox PARC. It has a history of nearly ten years and has mature technology. Disadvantages: Too complicated; destroys encapsulation; Special Java compiler is required. Dynamic AOP: Uses JDK
