Mobile Phones h2>
One day in April 1973, a man stood on the street in New York. He took out a wireless phone about two bricks and made a call. Passersby stopped and looked. This man is Martin Cooper, the inventor of the mobile phone. At that time, Cooper was an engineering technician for the famous Motorola Company in the United States. The world’s first mobile phone call was made to an opponent he worked at Bell Labs. After 29 years of working at Motorola, Martin Cooper founded his own communications technology research company in Silicon Valley. In 2013, he became the chairman and chief executive officer of this company. Martin Cooper’s idea at the time was to let the media know that wireless communications—especially small mobile phones—are very valuable. In addition, he also hopes to arouse the interest of the Federal Communications Commission of the United States and support the former in the competition between Motorola and AT&T (AT&T is also a major communications company in the United States). In fact, going back further, we will find that the concept of mobile phones appeared as early as the 1940s. At that time, it was Bell Labs, the largest communications company in the United States, that started trial production. In 1946, Bell Labs produced the first so-called mobile communication phone. However, due to its large size, researchers can only put it on the shelf in the laboratory, and people gradually forget about it. It was not until the late 1960s that AT&T and Motorola became interested in this technology. At that time, AT&T rented out a very large mobile wireless phone that customers could install on a large truck. AT&T's vision is to develop a mobile phone with a power of 10 watts in the future and use the radio equipment on the truck to communicate. Cooper believes that this type of phone is too heavy and too big to be moved for people to take with them. Therefore, Motorola filed an application with the Federal Communications Commission of the United States, requesting that the power of mobile communication equipment should only be one watt, and the maximum should not exceed three watts. In fact, the radio power of most mobile phones today is only 500 milliwatts. From the registration of a mobile phone patent in 1973, it was not until 1985 that the first truly mobile phone in the modern sense was born. It puts the power supply and antenna in a box, which weighs 3 kilograms, which is very heavy and inconvenient. The user has to carry it on his back like a backpack, so it is called a "shoulder phone".
Notebook
In 1996, "Computer Magazine" in the United States mentioned that Compaq launched a laptop in November 1982, weighing 28 pounds (about 14 kilograms). It should be considered the earliest prototype of a laptop. However, IBM refused to accept this statement, insisting that a laptop named PC Convertible developed in 1985 was the true originator of notebook computers. The Americans quarreled endlessly, and the Japanese on the other side of the ocean were not happy anymore. Because they believe that the world’s first real notebook computer is Toshiba’s T1000. This product launched in 1985 uses Intel 8086 CPU, 512KB RAM, and has a 9-inch monochrome display without a hard disk. Can run MS-DOS operating system. In fact, the key to the dispute over "who made the first laptop" is that the Japanese and Americans have different understandings of the predecessor of the laptop. In the early 1980s, after IBM developed the personal PC, people dreamed of developing a PC product that could be carried around. In 1983, "National Electronics" magazine first proposed the concept of "laptop", which later evolved into a "laptop". At that time, companies including Apple, IBM, and Compaq launched this product. In the eyes of Americans, it is the development of "laptops" that urged the birth of laptops. In Japan during the same period, manufacturers such as Toshiba, Panasonic, and Sony were keen to develop a product called "mobile PC", which was based on the IBM PS/2 system and used an external power supply. Strictly speaking, the "mobile PC" developed by the Japanese at that time was closer to today's notebook computers. In particular, Japanese manufacturers emphasize portability in the process of developing "mobile PCs", which is in sharp contrast to the "laptops" designed by Americans that are too heavy to be carried to move. More importantly, it was after the launch of Toshiba T1000 that various new technologies and new products related to notebook computers appeared one after another, and the market began to develop comprehensively and rapidly. In 2001, the Journal of the American Computer Association wrote in a report commemorating the 20th anniversary of the birth of the PC, "In 1985, Toshiba launched the T1000, which brought people the concept of a'laptop' for the first time."
Tablet PC
The concept of tablet PC was put forward by Microsoft Corporation in 2002, but at that time the hardware technology level was not mature at that time, and the Windows XP operating system used was designed for traditional computers. The operation mode not suitable for tablet computers (Windows7 operating system is not suitable for tablet computers). In 2010, tablet computers suddenly became popular. The iPad was released by CEO Steve Jobs on January 27, 2010 at the Oberbojana Art Center in San Francisco, USA, allowing IT manufacturers to refocus their attention on the "tablet computer." The iPad redefines the concept and design of the tablet computer and has achieved great success, making the tablet computer a product that drives huge market demand. The concept of this tablet (Pad) is different from that of Microsoft (Tablet). The iPad makes people realize that it is not only the computer that installs Windows, Apple's IOS system can also do it. In 2011, Google launched the Android 3.0 Honey Comb operating system. Android is Google's software platform and operating system based on the Linux core. At present, Android has become one of iOS's strongest competitors.
In September 2011, with the release of Microsoft's Windows 8 system, the tablet camp expanded again. The applications developed and run by the Windows 8 operating system on computers and tablets are divided into two parts, one is Metro style The application of this is the current popular scene-based application, which is convenient for users to touch, and the operation interface is intuitive and simple. The second part is called the "desktop" application. Users can execute programs by clicking on the desktop icon, similar to traditional Windows applications. Metro application will become the mainstream of Windows 8.
