The OSI Layer-7 model is easy to understand and can't be remembered many times. I read it again today and found that it is more logical and easier to remember to look at the problem from the perspective of historical deduction. This article is not necessarily rigorous and may be flawed. It mainly serves to help people with poor memory. In general, the OSI model is developed from the bottom layer to the top layer. This model was first introduced because Americans have the need to communicate with
The second chapter is that lazy people have created a method, indeed many inventions are from the hands of lazy people, too lazy to wash clothes so invented the washing machine, lazy to walk so invented the car, lazy to climb stairs so invented the elevator, too lazy to go out to see the show so invented the TV, too la

Everything has its history, the modern computer has experienced the addition machine, multiplication machine, analysis machine, Turing machines and other stages. How does today's computer actually develop to this appearance now? I'm sure you'll be interested. The first people I guess is to use the finger to count, so most of the ancient civilization is used in the decimal. But found that 10 fingers are not enough, so people use a number of sticks, stones, rope and other things to count. But the

; then it came to J2EE. However, when you solve the problems related to the previous platform, the new technology you created also becomes a new platform, such as the CORBA platform and J2EE platform. In order to solve the incompatibility between different CPU hardware platforms, the operating system was invented; in order to solve the problems of different operating systems, the advanced language was invented

in English and Chinese. He used Chinese for 30 seconds and English for 45 seconds. Therefore, if two people recite the words in English and Chinese at the same time, the Chinese user will surely think of the ninth or eighth day in 30 seconds, and the English user will not be able to come here.

understand at a glance? Today, the computers we use are called "electronic computers" because they are still an important component of electronic components. With the electronic knowledge of my super poor hacker, I can still tell that the common electronic components include "resistance" and "capacitance". The resistance is related to it, what I learned in Middle School: "When the voltage is fixed, the current of the conductor is inversely proportional to its resistance" -- It's big! Do we have
