laitteistörakennetta

Laitteistörakenne refers to the physical components and their arrangement within a computer system. It encompasses all the hardware elements that make up a computer, from the central processing unit (CPU) and memory to storage devices, input/output peripherals, and the motherboard that connects them all. Understanding the hardware structure is crucial for comprehending how a computer functions, how it can be upgraded, and how different components interact with each other.

The core of the hardware structure is the motherboard, a printed circuit board that houses essential components like the CPU, RAM slots, expansion slots for graphics cards and other add-ons, and connectors for storage devices and peripherals. The CPU, often called the "brain" of the computer, performs calculations and executes instructions. Random Access Memory (RAM) is the computer's short-term memory, storing data and programs that are currently in use for quick access by the CPU.

Storage devices, such as hard disk drives (HDDs) and solid-state drives (SSDs), provide long-term storage for the operating system, applications, and user data. Input devices like keyboards and mice allow users to interact with the computer, while output devices such as monitors and printers present information to the user. The power supply unit (PSU) provides electricity to all the components. The specific arrangement and selection of these hardware components define the overall hardware structure, influencing the computer's performance, capabilities, and cost.
