电脑硬件
The hardware is the physical part of a computer system.
Relationships      
Parents 工程组件 A fundamental concept that applies in many engineering domains. An EngineeringComponent is an element of a Device that is a physically whole object, such as one might see listed as standard parts in a catalog. The main difference betweeen EngineeringComponents and arbitrary globs of matter is that EngineeringComponents are object-like in a modeling sense. Thus, an EngineeringComponent is not an arbtrary subregion, but a part of a system with a stable identity.
  产品 An Artifact that is produced by Manufacture.
Children 电脑组件An instance of ComputerComponent is a piece of computer hardware that has measurable performance characteristics in terms of different units. Components include hard drives, the performance of which can be measured in terms of BitsPerSecond required to transfer data to and from the drive, network adapters, the performance of which can be measured by PacketsPerSecond units of data transfered to and from the adapter, and other common components like ComputerMemory and CentralProcessingUnit.
 电脑输入设备A peripheral device that generates input for the computer such as a keyboard, scanner, or mouse.
 电脑输出设备Any peripheral that presents output from the computer, such as a screen or printer.
 硬件系统The class of hardware systems is the connection of three types of physical modules: instances of ComputerProcessor(s), ComputerMemory, and ComputerNetwork. ComputerProcessors execute instructions from ComputerPrograms, which usually include instructions to read and write data from memory, and send data via instances of ComputerNetworks.
 感测器Sensors include software that measures any attribute of executing computer programs or collections of executing programs, such as CPU utilization, aka load, memory utilization, I/O, overall task performance, network load and latency, etc.
