1. Concept of motherboard

The Base plate, also called motherboard motherboard, is a plaque containing a printed circuit board and to which are connected the components that make up a computer. Among the series of integrated circuits that has installed is the chipset, which is the connection between the computer, the RAM memory, expansion buses and other devices.
It is contained within a box of veneer and has a panel that allows you to connect external devices and many other internal connectors and sockets that facilitate the installation of components inside the box.
On the other hand, the Board includes a popularly known as BIOS and software which allows to carry out basic functions, such as: testing of devices, management of the keyboard, video, loading the operating system and the device recognition.
Then, the typical components of a plate base are as follows: one or more connectors power supply, CPU socket, slots of RAM and chipset.
In addition, the Base plate is split into two sections, the North Bridge (manages the connections between the computer, the RAM and the GPU memory) and the South Bridge (allows the connection between peripherals and the storage devices, such as hard drive.
Most of the plates bases sold after the year 2001 are classified into two groups: for AMD processors and Intel processors. The most popular manufacturers include: Intel, MSI, Gigabyte Technology, Foxconn, Epox, Biostar, Asus, Via.

2. Definition of motherboard

The motherboard, also known as a motherboard or motherboard (motherboard or mainboard English) is a printed circuit card that connect the components that make up the computer or computer. It is a fundamental part when it comes to put together a desktop PC or laptop. It has installed a series of integrated circuits, which include integrated auxiliary circuit, which serves as a hub between the microprocessor, memory random access (RAM), expansion slots, and other devices.
It is installed inside a box or Cabinet that is usually made of veneer and has a panel for connecting external devices and many internal connectors and Sockets to install components inside the box.
The base plate also includes a firmware called BIOS, that allows you to perform basic functions, such as testing devices, video and keyboard handling, device recognition and loading of the operating system.
Components of the base plate
A typical motherboard supports the following components:
• One or several power connectors: these connectors, power supply provides the base plate different voltages and currents necessary for its operation.
• The CPU socket is a socket which receives the microprocessor and connects it with the rest of components through the base plate.
• Common slots of RAM memory, in number of 2 to 6 in the base plates.
• Chipset: a series of electronic circuits that manage data transfers between the different components of the computer (processor, memory, graphics card, unit) of secondary storage, etc.
It is divided into two sections, the Northbridge (northbridge) and Bridge South (southbridge). The first manages the interconnection between microprocessor, RAM and graphics processing unit; and the second between peripherals and storage devices, such as hard drives or optical drives. The new line of desktop processors tend to integrate own memory controller on the processor Inside that they are slow to degrade approximately 100 to 200 years.
• Clock: regulates the speed of execution of the instructions of the microprocessor and the internal peripherals.
• The CMOS: a small memory that preserves some important information (such as the configuration of the equipment, date and time), while the computer is not powered by electricity.
• The CMOS battery: provides the electricity needed to operate the circuit constantly and that the latter do not turn off losing series of saved settings.
• BIOS: a program recorded in a non-volatile memory (formerly in ROM memories, but long since used flash memories). This program is specific to the motherboard and is responsible for low level between the microprocessor and some peripheral interface. Retrieves, and then execute the instructions of the MBR (Master Boot Record), or registered on a hard disk or SSD, when you start the operating system. Modern computers currently replaced by the GPT MBR and BIOS by Extensible Firmware Interface.
• Bus (also called internal bus or English front-side bus'): connects the microprocessor chipset, it is falling into disuse from HyperTransport and Quickpath.
• The memory bus connects the chipset to the temporary memory.
• The expansion bus (also called bus I/o): unites the microprocessor to the input/output connectors and expansion slots.
• The input/output connectors that normally meet the PC 99 standard.
• The expansion slots: it's receptacles that can accommodate expansion cards (these cards are used to add features or to increase the performance of a computer; for example, a graphics card can be added to a computer to improve 3D performance). These ports may be port ISA (old interface), PCI (in English Peripheral Component Interconnect) or AGP (in English Accelerated Graphics Port) and, the latest, PCI Express.
With the evolution of computers, more and more features have been integrated on the motherboard, such as electronic circuits for the management of the IGP (English Integrated Graphic Processor) video, sound or networking (10/100 Mbps/1 Gbps), thus avoiding the addition of expansion cards.
There are also different sets of pins that are used to configure other devices on the plate:
JMDM1: Used to connect a modem which you can switch on the system when it receives a signal.
JIR2: This connector allows connecting IrDA infrared modules, having to configure the BIOS.
JBAT1: Used to be able to erase all settings as a user we can modify and reset the settings that come from the factory.
JP20: It allows you to connect the front panel audio.
JFP1 & JFP2: Used for connecting the front panel switches and LEDs.
JUSB1 and JUSB3: It is to connect the front panel usb ports.

3 Meaning of motherboard

The notion of plate is used in multiple ways. It can be a table or sheet that displays data or which enables the execution of certain duties. Mother, on the other hand, is a woman or a female has given birth or who plays a role similar to the of who gave birth.
In the field of computer science, referred to as the motherboard to the card that brings those printed circuits that interconnect the various elements that make up a computer.
The motherboard, which may be called plate base or motherboard (in English), settles on a sheet and has multiple sockets and connectors that allow you to establish appropriate linkages between the elements. The plate is integrated a firmware known as BIOS that starts to operate together with the computer's power and that provides the basic instructions to hardware, in addition to loading the operating system.
On the motherboard there are also spaces for the installation of RAM memory and the microprocessor. It has, on the other hand, a set of circuits known as chipset, different connectors that allow electrical components and feed multiple ports for connecting peripherals.
Another important element of the motherboard is the CMOS memory, which stores the date, time and the initial configuration of the computer when the machine is off, and therefore do not receive the power. The CMOS is powered by a battery that allows you to keep working steadily.
