What is the main purpose of linux system?

In the past, Linux was mainly used as the operating system of the server because of its cheapness, flexibility and Unix background. Traditionally, Linux-based "LAMP (combination of Linux, Apache, MySQL, Perl/PHP/Python)" technology has been widely welcomed by developers and is also the most commonly used platform for website service providers. Because of its low cost and high settability, Linux is often used in embedded systems, such as set-top boxes, mobile phones and mobile devices. On mobile phones, Linux has become the main competitor of Symbian OS. On mobile devices, it becomes a substitute for Windows CE and Palm OS. At present, the popular TiVo digital camera uses customized Linux. In addition, there are many hardware-based network firewalls and routers, such as some LinkSys products, which are internally driven by Linux and use the firewall and routing functions provided by the operating system. There are more and more supercomputers using Linux. According to the list of the top 500 supercomputers in June 2008165438+1October, the fastest supercomputer in the world uses Linux as its operating system. Of the 500 listed systems, 439 (87.8%) use Linux as the operating system. Sony PlayStation 3 released in 2006 can also use Linux operating system. It has a yellow dog Linux that can make it a desktop system. Previously, Sony also launched a DIY component called PS2 Linux for their PlayStation 2. Ubuntu resumed PPC support (including PlayStation 3) from version 9.04. With the implementation of low-cost computers such as OLPC XO- 1 and ASUS Eee PC, many people are optimistic about the rapid growth of linux market share in the low-end PC market. However, after Windows entered this market, the market share of Linux declined rapidly. Now Windows has an absolute advantage in all PC markets.
