The following are various packages: Ethernet II encapsulation: Ethernet technology is based on Ethernet frames, also known as standard Ethernet frames (ARPA), that is, Ethernet II frames (originally known as DIX, the initials of the three launch companies Intel and Xerox are combined ). The frame format is as follows: Figure 1: Ethernet II packet format The fields in the Ethernet II frame are described as follows: · Preamble-also called "Syncwor

represented by a column chart and a pie chart respectively. The purpose of C is to ensure synchronization between M and V. Once M changes, V should be updated synchronously. MVC FrameworkModel-View-controller (MVC) is a software design model invented by Xerox PARC for programming language Smalltalk-80 in 1980s and has been widely used. Later, it was recommended to be the design model of Oracle's Sun's Java EE platform, and is welcomed by more and mor

M: Model Mode V: view C: Control (1) It is generally used to describe the three-layer structure of JSP websites. Model is the underlying database, view is the JSP page, and control refers to the control between the two, such as JavaBean and servlet. MVC originally exists in Desktop Program In, M is the exponential data model, V is the user interface, and C is the controller. The purpose of using MVC is to implement m and V. Code So that the same program can use different forms of representat

MVC has become our most misuse model,MVC is often misused because different MVC variants are obfuscated. Classic MVC Classic MVC in the 1970s S, Xerox PARC Trygve proposed the concept of MVC. It is also applied in the Smalltalk system. to distinguish it from other types of MVC, classic MVC is used in history. Classic MVC Mode Model: encapsulate domain data and logic View: query domain data and present it to users Conctroller: interc

MVC(Model-View-controller, Model-View-controller mode) is a software architecture mode in software engineering. It divides a software system into three basic parts: model, view, and controller ).

First, a new doctor(Fresh mintedPhD) after five years of training, you can select a professor for life. Once you pass the course, you will have no worries about your job, and you can study it with one mind. Of course, the school also knows: the vast majority of these tenure professors There is no potential for research. Nothing

We have been emphasizing the importance of the routing information protocol in the routing protocol. Based on the previous introduction, I don't know whether you have understood its principles. Next we will summarize the features of this Protocol. The routing information protocol was originally designed for Xerox PUP (PARC universal protocol). the routing information protocol was collectively referred to as "GWINFO" in the

protocol used in the autonomous region is called the internal gateway protocol, which is commonly used with RIP and OSPF. The external gateway protocol is mainly used for routing selection between multiple autonomous regions, common are BGP and BGP-4. The following is a brief introduction. RIP route protocol The RIP Protocol was originally designed for the Xerox parc common protocol of the Xerox network sy

The routing information protocol, as the name suggests. A standard technology that manages the data distributed by a route based on the routing information protocol. We will summarize the features of this Protocol. Before that, let's take a look at its basic information. The routing information protocol was originally designed for Xerox PUP (PARC universal protocol). the routing information protocol was collectively referred to as "GWINFO" in the

external gateway protocol EGP based on whether they are used in an autonomous domain ). The Autonomous Region refers to a network with a unified management organization and a unified routing policy. The routing protocol used in the autonomous region is called the internal gateway protocol, which is commonly used with RIP and OSPF. The external gateway protocol is mainly used for routing selection between multiple autonomous regions, common are BGP and BGP-4. The following is a brief introductio

Ethernet (EtherNet)Originally created by Xerox, the Ethernet was developed jointly by DEC, Intel and Xerox three companies in 1980 as a standard. Ethernet is the most widely used local area network, including standard Ethernet (10Mbps), Fast Ethernet (100Mbps), Gigabit Ethernet (Mbps), and 10G Ethernet, all conforming to the IEEE802.3 Series standard specification.(1) Standard EthernetThe first Ethernet onl

as bus type and ring type LAN), that is, everyone shares the same transmission medium. While a transmission medium can only be used by one computer at a time, who can use or access the transmission media at a certain moment? This requires a common guideline for controlling and coordinating the simultaneous access of a computer to a transmission medium, which is either a protocol or a media access control method. According to this, LAN can be divided into Ethernet, Token Ring network and so on.E

The evolution of the PC interface.1973 Year April for the first time the operation was completed in Xerox PARC Alto computer. The system is the first system to combine all the elements of a modern graphical user interface.1981 6 months of Xerox introduced the star, the successor of Business Aalto. Notable features: Double-click icons, overlapping Windows, dialog boxes andx-768 monochrome display. January 1

The routing information protocol, which is a very common and important protocol. If you want to learn the routing protocol well, you must understand the concept of this routing information protocol. Now let's take a detailed analysis. The routing information protocol was originally designed for Xerox PUP (PARC universal protocol). the routing information protocol was collectively referred to as "GWINFO" in the Xer
