Functional composition of smart phone

The following is my "smart phone function composition" arranged in the composition column. Welcome to check.

Functional composition of smart phones 1 2000, the number of mobile phones used in China was 85.26 million; 200 1 year is1.800 million; In 2002, it was 206.6 million; 269 million in 2003; In 2004, the usage of mobile phones increased rapidly to 355 million. From these data, we can see that the use of mobile phones is gradually increasing.

? The earliest mobile phones can talk wirelessly and are easy to carry. If you want to make a phone call, just press the button and you can talk to the other party. It has provided great help for you to communicate with the world. But as far as I know, only ten years ago, my mother was still using a mobile phone with a thickness of about 4 cm. Even the screen is less than half the size of my current mobile phone, and it is not a color screen. Only some basic functions, such as making phone calls and sending text messages.

Let's take a look at the current mobile phone. We can get a lot of fun from it, such as watching TV, chatting on QQ, playing games, listening to music and chatting online. Take my mobile phone, for example. My first mobile phone is a mobile phone worth more than 300 yuan. The screen of that mobile phone is not as big as my watch! Anyway, the mobile phone I use now is twice as big as the old one, and its functions are much richer than before, such as watching TV, taking photos, chatting on QQ, handwriting input method, playing games, recording videos, listening to music, chatting online and so on, which are all things that I didn't have in my old one.

The most important thing is the camera function in the mobile phone, which is convenient for us to use when traveling or going out. With it, we can photograph the beautiful scenery we meet. For example, at the seaside, others take out their mobile phones and digital cameras to take pictures of beautiful scenery. Not to be outdone, we immediately took out our mobile phones to take pictures. With the wide application of mobile phone, it has become an increasingly indispensable part of people's daily life. The extensive functions of mobile phones make some people almost inseparable from them.

The function of smart phone composition 2 The mobile phone that everyone is using now is called a smart phone. Then what do you mean? Smart phone? And then what? It refers to a mobile phone with an independent operating system like a personal computer. Users can install programs provided by third-party service providers, such as software and games, and access wireless networks through mobile communication networks. In fact, I think smart phone evolved from PDA, which is a scientific combination and sublimation of traditional mobile phone and personal computer, but it has obvious advantages compared with traditional mobile phone.

Smart phones have brought a lot of convenience to our lives. It can shop online like a computer. I remember last year, the teacher asked us to buy a book. Dad went to several bookstores nearby and found nothing. He had to drive for half an hour to the Xinhua Bookstore in the west of the city to buy it. It took a whole afternoon to go back and forth. This year, my mother installed Alipay on her smartphone and clicked Taobao several times. Many books are on display in front of us, and the prices are also discounted! I got some brand-new books the next day without leaving home. It's really convenient and affordable! Besides shopping, mobile phones can also show us the way. This summer, I reported on the Internet that I attended the freestyle training class in Bao Yugang Swimming Pool, but my mother and I haven't been to the swimming pool yet, and we don't know the specific location, except that it is near the intersection of Tianmushan College. After we got off at the intersection of college by bus, there was no sign of swimming pool. We walked along Xueyuan Road for more than ten minutes without seeing it. At this time, my mother thought of the mobile phone and took it out to look for the map, only to know that we were going in the wrong direction and going further and further. In fact, it's close to where we got off. Thanks to this smart phone, otherwise we really became? Far apart? Yes

Smartphones make our communication more convenient. It can chat online like a computer, but it is more convenient than a computer because it can communicate with each other anytime and anywhere. Organized at school? Hand in hand, I met Jiang Dingrou from Fengshuling Primary School in Chun 'an. Usually only through letters, slow, lack of color, because letters only have black handwriting. I learned her QQ number this year and chatted online with my mother's smartphone. We finally saw each other's voices and smiles. After that, we often talk about the study and interesting things in our class through smart phones in our spare time. Two people are often talked about by each other. Touched? Have to? One by one? Wu wear the belly to laugh. In June this year, my six-year-old cousin, who is far away from home, participated in the martial arts performance of the District Children's Group and won the Excellence Award. At the moment when she received the award, my mother and I were on the way, and my mother had good news from her on her smartphone. There will be a video soon. Show it to me in an orderly way. Although hundreds of miles apart, we shared the joy of success together at the first time.

Of course, the development of smart phones will be broader in the future. Not only personal communication, information management, schedule, task arrangement, multimedia application, web browsing, etc. , such as: stock, news, weather, traffic, goods, application download, music picture download, etc. Will it? Smart city? 、? Smart family? An important means. Realizing wireless synchronization can release all the functions of smart phones, and make a mobile phone a time management tool, a mobile office platform, and remotely control the TV, rice cooker, air conditioner and washing machine at home. It's really good to think about trivial things in family life, such as washing and cooking, all done by mobile phone! According to my father, smart phones have been used in the military fields of various countries. Such as taking photos, positioning and tracking, inertial sensing, Bluetooth signal, electronic compass and other functions. Smart phones can be used for wireless remote control, that is, through the wireless signals of smart phones, you can remotely control your own micro drones and robots, and you can also take over other drones and robots to complete reconnaissance and monitoring tasks, and watch the video images taken by drones in real time on the display screen. It can also be used for battlefield communication and reconnaissance, and as a battlefield situation awareness terminal.
