what is a motherboard

 You may have the critical components needed to get a functioning system: CPU RAM PSU HDD / SSD. But where does everything connect? What combines everything for it to function as one? Motherboard.

The motherboard serves as the means of information between the vital cities. The circuits are the highways and the capacitors are the gas stations.

At the first peak, a motherboard contains various grooves and components that are soldered and integrated into it and it may seem quite intimidating at first glance but for the most part, it is mostly quite simple and each part of this board has a function.

What Is a Motherboard?

Each board has a different place to place its components but in fact, they are all coordinated in the same way.

The central processing unit (CPU) slot is usually a square socket with many pinholes located near one end of the micro atx motherboard. This is where the CPU and cooling go. The processor is the brainpower and the cooling sink is placed on top of it to extract heat from the processor.

Usually in front of the CPU slot are 2 or 4 long and thin rectangular slots with latches at both ends. These are the Dual In-Line Memory (DIMMs) that receive the random access memory (RAM) and when they are in place the latches will insert them inside. RAM is basically used to store computer data to help the processor.

A smaller rectangular piece with 24 box-shaped inputs (20-pin previous generation) is where you connect the Advanced Technology Extended (ATX) power supply unit (PSU) to power the motherboard. There may be a similar piece with 4-8 box-shaped inputs that can be plugged into a +12 volt power cord to transfer additional power to the micro atx motherboard.

Alongside the 24-pin ATP receiver, there is usually an earlier-generation floppy drive (FDD) connector to get the same previous-generation floppy drives you read about in books. 

Next to these, there are usually several previous generation integrated environment (IDE) connectors that get older hard drive (HDD) disks before the hard drive disks become serial.

Serial Advanced Attachment Technology Attachment (SATA) connectors may vary from 2 to 12 depending on the type of motherboard purchased. These are much more efficient than IDE connectors because they allow for smaller wires that allow for better airflow along its entire length.

Accelerated first-generation (AGP), PCI or PCIe (PCIe) connected graphics ports are usually located south of the CPU slot and are completely designed for graphics cards. AGP is rare nowadays as are PCI slots as PCIe is today the modern look capable of providing a much faster process for video cards.

Colored components on one side of the motherboard protruding slightly beyond the edge are intended for connectors for integrated peripherals. 

This peripherals typically include (PS / 2) for keyboard and mouse serial port parallel port (for older or modern printers) video graphics array digital video input high definition multimedia interface (VGA / DVI / HDMI), for Monitors Firewire / IEEE (network/video/audio), USB (universal serial bus), Ethernet (network) and audio (for speakers).

There may be pins 3 4 or up to 7 or 8 pins grouped with labels below or inside them protruding; It is intended for the case: fan input audio input USB input LED input (light-emitting diodes) and/or power / reset button. Not all of these features will be included anyway; Some may contain only power.

Integrated Components That Do Not Need Input

These parts can be left alone. They are usually few or useless for us to mess with chips or boxes written on them that can be seen with a magnifying glass or a particularly good sight. But if you want to know everything or want to be a Mobo guru here is information about them.

The capacitors can vary in shape and length but are scattered throughout the micro atx motherboard. These store electrical charge and are used for several reasons such as smoothing the power supply output or blocking direct current.

The integrated black chips that look like spiders with multiple metal legs can be used for quite a few things like floppy controller serial ports, parallel ports temperature sensor fan speed monitor, or integrated audio codec.

The basic input chip (BIOS) flash looks like one of the integrated black chips; However, it has a central use that cannot be skipped. 

This is built into the software which is the first code that the computer runs when it is turned on. The main function of the BIOS is to configure the hardware and boot the operating system. This is significant because if we did not have it then no external input would be detected.

The Complementary Metal-Metal-Oxide Conductor (CMOS) is a metallic-looking item that contains a battery inside. You can push this battery in case you need to reset the BIOS password reset time or the battery will break down.

Cooling refrigerants can be distributed on the Southbridge which usually applies the slower capabilities of the micro atx motherboard or on an integrated graphics processor. These protruding metal sheets just like using a processor attract heat from the installed component.
