Moderkretskort

Moderkretskort, often referred to as a motherboard, is the central printed circuit board (PCB) in a computer. It serves as the primary communication hub, connecting all the essential components of the system. This includes the central processing unit (CPU), memory (RAM), storage devices, graphics card, and peripherals. The motherboard houses the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface), which is responsible for initiating the boot process and providing a basic interface for hardware configuration.

The physical layout of a motherboard is characterized by various slots, connectors, and chips. Expansion slots, such as PCI Express (PCIe), allow for the addition of components like graphics cards and network cards. SATA ports are used to connect hard drives and SSDs. USB ports provide connectivity for external devices. Power connectors deliver electricity from the power supply unit to the motherboard and its connected components.

Different motherboard form factors exist, such as ATX, Micro-ATX, and Mini-ITX, which dictate their size and the number of expansion slots they can accommodate. The choice of motherboard is crucial as it influences the compatibility of other hardware components and the overall performance and expandability of a computer system. It is the backbone that integrates all the individual parts into a functional whole.
