keskusyksiköltä

Keskusyksikkö translates from Finnish to English as "central unit" or "main unit." In computing, this term most commonly refers to the central processing unit (CPU), which is the primary component of a computer responsible for executing instructions. The CPU performs the basic arithmetic, logic, control, and input/output operations specified by the instructions in a program. It is often referred to as the "brain" of the computer.

The term "keskusyksikkö" can also be used more broadly to refer to the entire computer case, often called the tower or chassis, which houses the main components like the motherboard, CPU, RAM, storage devices, and power supply. In this context, it's the physical enclosure that contains the core functional parts of the computer system.

In industrial or embedded systems, a "keskusyksikkö" might denote a control unit or a main processing module that manages the operations of a larger system or network of devices. The specific meaning depends heavily on the context in which the term is used, but it invariably points to a core component or the main housing of a processing system.
