Web defect:
The first defect: non-localization. The web way is the most attractive thing that it is that it only needs a browser. All users have greatly simplified from server, HTML, and related technologies. It has simplified the technical requirements for users to use the network, bringing non-network applications. Ignore the impact. However, the implementation of this architecture and the guarantee of security, limiting its information storage in the client (cookies is a very limited exception), which means that even exactly the same information, users need to use each time It is necessary to download from the server every time, its efficiency is much efficient than the method that allows local storage terminal software "once downloaded, repeatedly read". Although the occurrence of broadband has a certain extent of multiple times of time to read, the broadband is developed, no matter whether it is going to transcend the local hard disk in the short term, it seems impossible thing. The congenital restriction of HTML technology also determines even the same expression effect, its execution efficiency cannot be compared to the local terminal program written in advanced languages, which makes an important factor such as a small program such as Java. However, in order to repair the replenishment, in order to achieve its versatility, the Web application is unable to match the local terminal program - a good example is how popular Web Mail, no matter how popular Web mail Powerful, but most advanced users still like to use Email terminal software to send and receive mail.
However, if we are in order to web, we have to terminate all Web-based applications, and will encounter problems we have to encounter before the Web appeared. Users must install a terminal program for a small app. More and more terminal programs will eventually make the user not bothering, but also make the user's system efficiency, so we will find that many network service providers have launched the terminal board for their services, but how to persuade users to new Install a terminal and guilty. An important idea of IMU is to solve these two problems very well - IM as one of the most important network applications, users have accepted and mostly will use them as an indispensable network terminal, then Other network applications do not need to design new network terminal programs, but can be implemented as a custom version of the IM program or a plug-in, so that the terminal program is only one IM software, but the functionality that can be implemented can be constantly Expand, give full play to the advantages of the terminal program.
The second defect: non-instantity. Strictly speaking, there is almost no real instant messaging application, but IM only narrows the interval between terminal software and server interaction to a small almost ignore the logging time unit. However, as we are always in realization, IM software is realized very well, and most of the power maps use web to implement instant applications, it is not as good as IM software. And this is exactly an exclusive advantage of IM software. I believe that everyone is already very familiar with MSN, this IM software has a function of making many users. It is the email to arrive reminder. Once your Hotmail mailbox has received an email, your MSN Messager will immediately remind you. Similar functions, some Mail Checker software can also be implemented, but the method is to collect mail through the POP3 protocol according to the time interval set by the user, and do not do real immeises on the one hand, and the effective rate implemented on the other hand is also very low. . And MSN implements the function of Mail Checker, not only reaches the effect of instant reminders, but also performs high execution efficiency, only accepts the information of the server when the email arrives, and makes a reminder, usually do not need to be like a normal program. Check the mailbox.
Way with IM cooperation
First, work with Email service providers. Second, cooperate with the forum service provider. three. Cooperate with the schoolmates.
