Computer Motherboards And Daughterboards

A computer motherboard, also known as a mainboard, system board, or logic board, is the primary printed circuit board (PCB) found in personal computers and other electronic devices. It is responsible for providing the electrical and mechanical connections between various components of the computer, including the central processing unit (CPU), memory, storage devices, and input/output (I/O) devices. The motherboard also contains the firmware that controls the basic input/output system (BIOS) and manages the power supply and cooling systems. A daughterboard, also known as a daughter card or expansion board, is a secondary PCB that is attached to the motherboard to provide additional functionality or to upgrade existing components. Daughterboards can be used to add features such as audio and video capabilities, network connectivity, or additional ports for peripherals. They can also be used to upgrade existing components such as the CPU or memory. The relationship between the motherboard and daughterboard can be compared to that of a parent and child. The motherboard is the parent that provides the basic infrastructure and support for the computer, while the daughterboard is the child that adds additional capabilities and features. In order for a daughterboard to be attached to a motherboard, it must have a compatible interface. Common interface types include Peripheral Component Interconnect (PCI), Accelerated Graphics Port (AGP), and Industry Standard Architecture (ISA). These interfaces allow daughterboards to communicate with the motherboard and other components of the computer. Overall, the use of daughterboards allows for greater flexibility and customization in computer design, as well as the ability to upgrade or replace components without having to replace the entire motherboard.
