What company is arm, and what is the relationship between Qualcomm's nvidia, Samsung and Apple?

ARM is a British chip design company, which is famous for designing chips with low power consumption and high performance. Its designed CPU and other chips occupy more than 90% of the mobile phone and tablet computer market, and are widely used in many other industrial fields. The company does not directly produce chips, but focuses on chip design and authorizes other companies to produce them. Qualcomm, Samsung, Apple and NV are all AMR customers, such as the ARM processing chips used by Samsung and Apple's mobile phones. At first, ARM was a little-known company. I tried to enter the PC market in the early days, but was blocked by giants such as Intel. Instead, it focuses on the research and development of low-power embedded chips and gains benefits by authorizing other production companies. Because of the low-key behavior, until the rapid development of mobile and portable communication terminals in recent years, many talents discovered the great energy of this once unknown small company. Some people even say that if anyone can beat Intel in the future, it may be ARM, especially this time Microsoft's WIN8 began to support ARM processors, which brought the days of direct competition between ARM and Intel closer, and also made chip giants like Intel feel an unprecedented threat.
