logical unit
Computing term for a functional component that performs logical operations, such as an arithmetic logic unit (ALU) or a logical partition.
A logical unit is included inside the CPU.
This logical unit processes complex operations at high speed.
演算装置 (arithmetic unit) specifically handles arithmetic operations, while 論理装置 (logical unit) focuses on logical operations; both are often combined in an ALU.
Compound of 論理 (logic) and 装置 (device, unit). A straightforward technical term with no obscure historical derivation.
