components; constituent devices
Technical term used in computing and engineering to refer to the individual devices or units that make up a system.
All the components of this system are modularized.
I compiled a list of the network's constituent devices.
部品 is a general term for parts or components, often mechanical or electronic, while 構成機器 specifically refers to devices or equipment that form a system, emphasizing their role in the configuration.
コンポーネント is a loanword used broadly in software and hardware, similar to 構成機器 but more abstract and not limited to physical devices.
Compound of 構成 (こうせい, 'configuration') and 機器 (きき, 'equipment'). The exact historical derivation is uncertain, but the term is a straightforward technical coinage.
