The Laboratory Use of Computers
Published in Grinberg Nelu, Rodriguez Sonia, Ewing’s Analytical Instrumentation Handbook, Fourth Edition, 2019
The motherboard contains the buses (both data and address) by which all of the system components communicate with one another. Increases in system bus speeds almost always lead to performance improvements. This is because it increases the speed by which computer components communicate with one another. Modern PCs typically split the bus into a system portion that links high-speed components (such as the memory and the video card) to the CPU and a slower local bus for connecting disks, modems, and printers. The speed of the system bus is especially important in terms of the CPU accessing main memory, as memory access speed increases with bus speed. One should also note the motherboard can limit the amount of memory that can be installed on the PC based on the number of available memory slots and the maximum-sized memory cards supported.

Motherboard: The motherboard (or main board or system board) of a computer represents interconnected key hardware components of a computer. External devices and I/O ports are also connected to the motherboard through a computer bus. Various IC packages and other hardware devices are mounted on the motherboard, which is located in the computer housing. Other devices (various cards including DAQ) are mounted in the expansion slots of the computer housing. A typical architecture of a computer motherboard is shown in Figure 4.8a. It shows the main components such as the central processing unit (CPU), memory, and clock; expansion slots for hardware such as DAQ, network card, video card, storage, sound card, and memory expansion card; and I/O ports for peripheral devices and communication, such as monitor, keyboard, mouse, printer, scanner, external storage, and local area network.
Reliability and fault-finding
Published in Mike Tooley, PC Based Instrumentation and Control, 2013
The Basic Input and Output System (BIOS) is a program stored in a read-only memory (ROM) chip on the motherboard. When a computer is first powered-up the BIOS program performs a number of functions including performing the Power On Self Test (POST) and loading the operating system. The BIOS assists with the management of PC hardware via a set of BIOS run-time service routines.
Positive lean: merging the science of efficiency with the psychology of work

As a manufacturing example, consider a system that produces personal computers. A key component of a personal computer is the printed circuit board (PCB) that serves as the motherboard. A step in the production of these PCBs, illustrated in Figure 2, is surface mount assembly, in which electronic components are positioned on the board. The main inputs to the surface mount process are the raw circuit boards, components, solder paste and electricity. The resources include one or more pick-and-place machines (chip shooters) and human operators. The outputs are boards with components (‘stuffed’ boards). The customer is the wave soldering stage, in which a reflow oven is used to solder the components in place. The orders are production triggers, which could be kanban signals in a pull system or order releases in a push (MRP) system. If a demand occurs when there is no inventory of assembled boards available, then the order incurs waiting time.
