The operating system handles basic tasks such as managing and configuring memory, prioritizing the supply and demand of system resources, controlling input and output devices, operating the network, and managing the file system. The operating system also provides an interface for the user to interact with the system.Computer inventor Johann von Neumann. Computer is one of the most advanced scientific and technological inventions in the 20th century. It has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality. Its application field has expanded from the initial military scientific research application to various fields of society,It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers. The more advanced computers include biological computers, photonic computers, and quantum computers. HardwareComputer hardware, including all physical parts in the computer, to distinguish the data it contains or execute from the software that provides instructions for the hardware to complete tasks; mainly includes: chassis, motherboard, bus, power supply, hard disk, storage controller, Interface cards, portable storage devices, built-in memory, input devices, output devices, CPU fans, buzzers, etc.Phone Smartphone is a general term for the type of mobile phone that has an independent operating system and independent operating space, and can be provided by third-party service providers such as software, games, and navigation by users, and can achieve wireless network access through mobile communication networks. .Printer A printer is one of the output devices of a computer and is used to print the results of computer processing on related media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise. There are many types of printers. According to whether the printing element has a striking action on the paper, it is divided into impact printers and non-impact printers. According to the structure of printing characters, it is divided into full-shaped character printers and dot-matrix character printers. NetworkNetwork hardware is the electronic equipment required to communicate and interact between devices on a computer network. Specifically, they mediate data transfer in computer networks. The unit that is the last receiver or generates data is called a host, end system or data terminal equipment.Other network hardware used in computers includes data center equipment (such as file servers, database servers, and storage areas), network services (such as DNS, DHCP, email, etc.), and equipment that ensures content delivery.InternetThe Internet started in 1969 with the Arpanet in the United States. Usually the internet refers to the Internet in general, while the Internet refers specifically to the Internet. This method of connecting computer networks to each other can be called "Internet interconnection". On this basis, a global Internet network covering the whole world is developed called the Internet, which is a network structure that is connected to each other. The Internet is not the same as the World Wide Web. The World Wide Web is just a global system based on hypertext links and is one of the services that the Internet can provide.SiteMapH5 Gamescomposition CCIE training Android tutorial ios tutorial learning computer GAME NEWS Learning anime production zendchina Cloud Wing Network Computers Tutorial whycomputer.com © Computer and internet knowledge
