Mobile phone, originally just a communication tool, was commonly known as mobile phone in the early days. This is a portable telephone terminal that can be widely used. It was originally developed from the battlefield mobile phone manufactured by Bell Laboratories in 1940.
1958, Soviet engineer Leonid Kupriyan Norwich invented лк- 1 mobile phone, 1973, American Motorola engineer martin cooper invented the world's first commercial mobile phone. So far, it has developed into the 4G era.
Mobile phones are divided into smart phones and non-smart phones. Generally, the performance of smart phones is better than that of non-smart phones, but the performance of non-smart phones is more stable than that of smart phones. Most non-smart phones and smart phones use the CPU of British ARM company. Smart phones have higher main frequency, faster running speed, faster processing program tasks and more convenient daily life, while non-smart phones have lower main frequency and slower running speed.
Smart phones, like personal computers, have independent operating systems, most of which are large-screen machines, touch capacitive screens, and some are resistive screens, which are powerful and practical. Users can install programs provided by third-party service providers, including games, which can continuously expand the functions of mobile phones and realize wireless network access through mobile communication networks.
Generally speaking, it is a simple formula of "1+1=" PDA+mobile phone = smart phone ". Broadly speaking, smart phone not only has the function of talking on mobile phone, but also has most functions of PDA, especially personal information management based on wireless data communication, browser and email functions. Smart phones provide users with enough screen size and bandwidth, which is not only convenient to carry around, but also provides a broad stage for software operation and content services. Many value-added services can be developed in this respect, such as: stock, news, weather, transportation, goods, application download, music and picture download, etc.
