What are the basic parts that make up a computer hardware system?

The basic parts of a computer hardware system are: host and input/output devices. The hardware system refers to the physical equipment that constitutes the computer, that is, the physical components composed of mechanical, optical, electrical, and magnetic devices with computing, control, storage, input, and output functions. The computer hardware mainly includes: CPU, memory, output devices and input devices; the CPU and memory are collectively called the host.

Hardware system refers to the physical equipment that constitutes a computer, that is, the physical components composed of mechanical, optical, electrical, and magnetic devices with computing, control, storage, input, and output functions. Such as CPU, memory, floppy disk drive, hard disk drive, optical disk drive, motherboard, various cards and the host computer, monitor, printer, plotter, modem, etc. in the complete machine. The complete machine hardware is also called "hard device".

The computer hardware mainly includes: CPU, memory, output devices and input devices; the CPU and memory are collectively called the host.

Minimum hardware system

The hardware design of embedded systems varies depending on their application scenarios and application systems. In general, users can choose the appropriate microprocessor type according to their own requirements, and match it with different types of peripherals according to the corresponding interface circuits to form application systems with different purposes and sizes.

These systems, no matter how large they are, can be divided into minimum systems composed of core circuits and peripheral interface circuits required for various external devices from a hardware perspective. Usually the minimum hardware system refers to a core system composed of a processor, a storage circuit composed of SDRAM and FLASH, plus some necessary auxiliary circuits.

The minimum hardware system is not only the core part of the entire hardware system, its composition also has an important impact on the software system. Its composition determines the design of the Bootloader at the bottom of the software system. It is also an embedded operating system. basis for normal operation.

In other words, the minimum hardware system and the lowest-level minimum software system above it constitute the most basic and core part of the embedded system.
