Dell Precision T3600 System Motherboard, used in professional CAD Workstations. Manufactured in 2012. A motherboard (also called mainboard, main circuit board, MB, mobo, base board, system board, or, in Apple computers, logic board) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems.
Its main functions are as follows: To serve as a central backbone to which all other modular parts such as CPU, RAM, and hard drives can be attached as required to create a computer; To be interchangeable (in most cases) with different components (in particular CPU and expansion cards) for the purposes of customization and upgrading
Components directly attached to or to part of the motherboard include: At least one CPU (central processing unit), which performs most of the calculations that enable a computer to function. [49] It can be informally referred to as the brain of the computer. [50]
An opened ATX case, front towards right. Components pictured include a microATX motherboard (top), a CPU (beneath the Cooler Master fan), a GPU (middle), and an SSD (right). The power supply is housed in the compartment at bottom. A computer case, also known as a computer chassis, is the enclosure that contains most of the hardware of a ...
The southbridge typically implements the slower capabilities of the motherboard in a northbridge-southbridge chipset computer architecture. In systems with Intel chipsets, the southbridge has been named I/O Controller Hub (ICH) and later replaced by Platform Controller Hub chipsets. In older Intel/AMD architectures the southbridge is usually ...
It was the first major change in desktop computer enclosure, motherboard and power supply design in many years, improving standardization and interchangeability of parts. The specification defines the dimensions; the mounting points; the I/O panel; and the power and connector interfaces among a computer case, a motherboard, and a power supply.
