The main body part of the computer except for the input and output devices

The host computer refers to the main body part of the computer except for the input and output devices The main body parts other than output devices. It is also a control box (container Mainframe) used to place the motherboard and other main components. Usually includes CPU, memory, motherboard, hard disk, optical drive, power supply, chassis, cooling system and other input and output controllers and interfaces.

In network technology, it is about terminal equipment that sends and receives information.

Host classification:

Computer host

refers to the computer hardware system used to place the motherboard and other main components (Mainframe). Usually includes CPU, memory, hard disk, optical drive, power supply, and other input and output controllers and interfaces, such as USB controller, graphics card, network card, sound card, etc. Those located inside the main chassis are usually called internal devices, while those located outside the main chassis are usually called peripherals (such as monitors, keyboards, mice, external hard drives, external optical drives, etc.). Usually, the host itself (after installing the software) is already a computer system that can run independently. Computers with special purposes such as servers usually only have the host and no other peripherals.

The emergence of virtual host technology is a major contribution to Internet technology and is good news to the majority of Internet users. Since multiple virtual hosts share the resources of one real host, the hardware costs, network maintenance costs, and communication line costs borne by each user are greatly reduced. The Internet has truly become a network that everyone can afford! Now, almost all American companies (including some families) have set up their own network servers on the Internet, and a considerable number of them use virtual hosts.

Each virtual host has an independent domain name and a complete Internet Server (supports World Wide Web, FTP, email, etc.) functions. Different virtual hosts on a server are independent and managed by the user. However, a server host can only support a certain number of virtual hosts. When this number is exceeded, users will experience a sharp drop in performance.

Virtual host technology is a technology used by Internet servers to save server hardware costs. Virtual host technology is mainly used in HTTP services to logically divide certain or all service contents of a server into multiple service units. , appearing as multiple servers to the outside world, thus making full use of server hardware resources. If the partitioning is at the system level, it is called a virtual server.
