Friends who know mobile phones, please talk about the advantages of Android system (people with mixed scores should respect themselves)

The advantage of Android is that it is very playable, and most of them are Free software. Moreover, the system version has higher requirements on mobile phone hardware than the two older mainstream systems. There are many models and many choices. The system version is still being gradually upgraded, and the system is full of vitality.

Needless to say, the advantages of ios are that it is Apple’s dedicated system. The emergence of each generation of iPhone brings a huge impact to the mobile phone market and brings a new revolution to the mobile phone market. It is the most worth buying mobile phone.

Bansai 3 can be said to be an inherited system, and its operation is still similar to the old Bansai system. If you are used to Symbian and want to try other system operating methods, this is a good choice. But now there are fewer models, and there are only 3 models on the market.

iOS is a nobleman, Android is a young man full of energy, and Bansai 3 is a person who is slowly stepping away from tradition.

If you have money, I recommend ip4. If you want to keep up with the trend again, Android is the way to go. If you don’t want to change too much, go to Symbian 3. What are the advantages of the Android system?

From an overall perspective, Android is indeed good, but fortunately it is flexible and personalized. Almost every function can be attributed to the fact that the system itself is very stable. Even if a certain function fails, it will not affect the entire system. It will just show the advantages of the Android system.

There are many software , easy to operate and fast network speed. What are the advantages of Android system over Symbian system, I want to know

Android:

Advantages: high playability, abundant software resources, open code compatibility Good, there is plenty of room for development.

Disadvantages: high hardware requirements, slow speed, too fake icons and interfaces, relatively complex architecture. After all, GOOGLE is in the Internet business, and the Android it develops is for wisdom, but wisdom is not humane. , which simply turns a mobile phone into a computer. GOOGLE doesn’t understand mobile phones.

Symbian 3:

Advantages: Stable, fast, low hardware requirements, elegant and simple interface, the quality of mobile phones supported by Symbian 3 is relatively good, the screen is good, and the 3D is good. It is very user-friendly and you can change everything you see and click on it.

Disadvantages: too new, less software, not as good as Android in compatibility.

Symbian 3 is actually an imitation of the Apple system. It has exactly the same functions, such as multi-touch. Many people confuse Symbian 3 with Symbian S60V3 V5. In fact, Symbian 3 is a brand new touch smart system.

Many people claim to have used the entire series of Symbian systems, but they have never used Symbian 3. They think Symbian 3 is the third version of Symbian S60, but in fact Symbian 3 is Symbian OS. The latest system in the series, much newer than Android.

Many people talk to you about Android and talk about the future. Why not talk about the present? What we buy is a mobile phone, not the future; what we buy is a mobile phone, not a computer.

Currently there are only 3 Symbian 3 machines, Nokia C6 C7 N8

In fact, the latest Symbian 3 system is a copycat of Apple. If you can’t afford Apple, just buy Symbian 3. Because the operation of mobile phones is almost 80% the same as that of Apple, Android is always said to be better than Symbian. I wonder where the superiority of Android lies.

Android is more like an entertainment and personalized platform, trendy and Radical, Symbian is more like returning to the essence of mobile phones, easy to operate. Android is now popular because it is open source and has good hardware configuration. Why is Android better than Symbian:

1. Symbian is a mobile phone with Internet access, while Android has a phone function Internet terminal.

2. High playability, abundant software resources, good program code openness and compatibility, and large development space. The first thing about the Android platform is its openness. The open platform allows any mobile terminal manufacturer to join the Android Alliance. Significant openness allows it to have more developers.

3. The expansion kit is highly adaptable. The machine's hardware is basically stronger than Symbian's.

4. Android is the only system that can compete with the iPhone. It has strong expansion kits and many application software.

Now it seems that if you are a person who pursues the trend and will not use a mobile phone for a long time, there is no doubt that Android is suitable for you, but the advantages of Symbian include being more stable and requiring more hardware. Low, save power. However, the shortcoming is that there is less software and the experience is worse than Android. However, if you do not have high requirements for mobile phones, Symbian is also a good choice, but to be honest, the current Symbian system is no longer updated. In other words, Symbian has basically withdrawn from the market, and Nokia has also been acquired by Microsoft to make Windows-based mobile phones.

Advantages of PE as a system

The graphical interface is more intuitive and convenient than working under DOS.

If PE is a hard disk version, it is also faster than Other ways are faster. Advantages of Android.

1. The stability of the Android system has won the favor of manufacturers.

As we all know, when HTC launched their first Android product G1, although the Android system already had a good reputation, it did not cause a sensation in the market. The reason was naturally that the G1 was equipped with The Android 1.1 version of the system has defects of one kind or another, both in terms of overall stability and basic functions. You have to know how many manufacturers are willing to use a system that is unstable and has imperfect basic functions?

However, the release of Android 1.5 version has solved the above problems to a certain extent. The system has become much more stable, and errors are no longer reported as frequently as before. At the same time, the basic functions of the system have also been improved a lot. The enhancement of call, text messaging and multimedia entertainment functions has made the Android system meet the requirements of most manufacturers. Therefore, manufacturers who have lost their appetite for half a year will naturally flock to this time. And, the sudden outbreak of Android system is not surprising.

2. The open source nature of the Android system allows manufacturers to put their own stamp on it at will

If the previous Symbian system and Windows Mobile system produced mobile phones according to other people's wishes, Then the Android system has completely let go of the hands of manufacturers. This is why we have seen the emergence of many excellent custom UIs such as HTC Sence and MOTO Blur in less than a year since the Android system was released. Their appearance not only enriches everyone's user experience, but is also the best platform for manufacturers to promote their brand concepts. Who wouldn't like such an operating system?

3. The free features of the Android system

Before the emergence of the Android system, most of us combined smart phones with high prices. Although smartphones are indeed more expensive than ordinary mobile phones in terms of hardware, the licensing fees for smart operating systems are the real culprit of their high prices. Nowadays, the open source features of Android mean that manufacturers do not need to pay high licensing fees when using the Android platform. This solves everyone’s development costs to a certain extent. Naturally, manufacturers can invest more energy in product research and development. . In addition, combined with the global financial crisis in 2009, manufacturers will naturally reduce their expenditures. Therefore, it is not surprising that they will fully develop the Android system in such an environment. Recently I have seen that HTC mobile phones are very popular. What are the advantages of HTC besides having Android system? What are the advantages of Android system?

There are many applications and games, and they are free. The control experience and visual effects are the same as those of IPHONE, and the system upgrade is easy.

In short, it is as fun as Apple, but not as troublesome. It’s not that expensive either. Briefly describe the advantages of the POS system

Electrodeionization (EDI) is to fill the desalination chamber of the electrodialyzer with ion exchange resin, and use the action of an external DC electric field to selectively migrate ions in a direction. The dissociation of water regenerates the mixed-bed resin in situ, so that the three processes of selective ion migration, deep desalination, and electrochemical regeneration of the resin occur simultaneously, which is equivalent to continuously obtaining a regenerated mixed-bed ion exchange column, and can produce efficiently and uninterruptedly. High purity water.

System process flow

Tap water-->Pretreatment-->Activated carbon-->Security filtration-->Reverse osmosis-->Electrodeionization

Main technical advantages and performance indicators

(1) The desalination rate is greater than 99.9%, and the efficiency is much higher than two-stage reverse osmosis and simple ion exchange.

(2) The more traditional ion exchange method desalination saves more than 95% of the resin

(3) The ion exchange resin does not need to be regenerated with acid and alkali, saving a lot of acid, alkali and cleaning water. Reduce labor intensity.

(4) Clean production, no wastewater treatment problems, and environmentally friendly.

(5) It has a high degree of automation and is easy to maintain. It can be designed into a complete membrane technology high-purity water production line.

(6) The produced water resistivity is 15-18MΩ·cm, pH is 6.5-7.0, silicon is <1.0ppb, and it is completely sterile.

(7) It occupies a small area, and a single system operates continuously, so there is no need to build a dedicated system.
