What is a Motherboard?
A motherboard is a computer's main printed circuit board (PCB). The motherboard is the core communications backbone and the connecting point for all components and external devices of a computer.
Motherboards are present in almost all computers, particularly desktop and laptop PCs. Chipsets, central processing units (CPUs), and memory are just a few of the components that connect through them. Wi-Fi, Ethernet, and graphics cards with the graphics processing unit, or GPU, are examples of external peripherals.
Acer, AS Rock, Asus, Gigabyte Technology, Intel, and Micro-Star International are among the motherboard makers.
How do motherboards function?
A big motherboard's PCB may include six to fourteen layers of fibreglass, copper connection traces, and copper planes for power and signal isolation. Expansion slots allow extra components to be added to a motherboard. These include CPU sockets, twin in-line main memory, PCI, PCI Express (PCIe), and solid-state drive M.2 slots, as well as power supply connectors.
A heat sink and fan regulate the heat generated by components such as the CPU. A Southbridge chip is typically used to provide additional connections such as PCI, Serial Advanced Technology Attachment, or SATA, Thunderbolt, USB, and other interfaces.
The CPU is often linked to DDR3, DDR4, DDR5, or integrated LPDDRx RAM, as well as PCIe. Point-to-point interconnects like Hyper Transport, Intel's Quick Path Interconnect, and Ultra Path Interconnect are used to do this. The motherboard that is selected typically impacts how many functions a computer will support.
The ATX motherboard, which is Intel's upgraded version of IBM's AT architecture, is often used in desktop computers. Designers of other form factors include the following:
- Micro ATX
- Mini-ITX
- Micro ITX
- Nano-ITX
- BTX
- Micro BTX
- Extended ATX
- Mini-ATX
Some memory controllers are now incorporated into CPUs, removing the requirement for Northbridge chips to handle memory from the motherboard. Integrated video has transitioned from a motherboard inserted peripheral to graphics-capable CPUs.
AMD's Ryzen processor features a system-on-a-chip architecture that makes the Southbridge chipset optional. Because of this CPU convergence, motherboard manufacturers' prices have decreased. They can provide basic systems for workplaces and entry-level computers, as well as specialized implementations for various CPUs that allow for platform updates.

Gaming motherboards are designed for high-performance PCs; they are much more powerful and feature-rich than desktop and laptop motherboards.
What is the location of the motherboard?
A computer motherboard is positioned within the computer chassis and connects the majority of the computer hardware and peripherals. The motherboard, which is the largest circuit board of a tower computer, is located on the left or right side of the tower.
What is the motherboard's primary function?
The fundamental role of your motherboard is to support all of the components that comprise your computer. When compared to the human body, the motherboard is the backbone, nervous system, and circulatory system all rolled into one. It physically supports many components, similar to a backbone; functions as a control centre, similar to a nervous system; and transfers voltage, similar to a circulatory system. For a more geeky analogy, the motherboard represents the black lion from Volition, functioning as the torso that connects all the other sections.
Components of a motherboard
Each motherboard is built to accommodate certain components, like CPUs and memory. They may house the majority of hard discs and accessories.
The following are the key components of a motherboard:
CPU:
Memory:
Instructions and data are briefly stored and executed in memory.
Storage interface:
solid-state or hard disc drive storage interface for persistent data and application storage;
ROM BIOS:
Non-volatile memory that stores firmware, for example, the basic input/output system, or BIOS, is provided by ROM BIOS.
Northbridge:
The Northbridge chipset links the CPU, memories, storage, and some other components.
Southbridge chipset:
which links to the Northbridge that links peripheral parts to the motherboard?
Cooling fans:
keep the interior working temperature at a comfortable level.
Peripheral connection slots:
for peripheral connection cards, including graphics cards but also communication adapters;
Peripheral device connections, such as USB ports and other external device connectors;
The backup battery,
which guarantees that critical system configuration data is preserved when main power is absent,
The power connection:
which connects to an external power source?
A standard motherboard is made up of several different components. Consider a motherboard to be a huge mosaic of electrical connections that connects the various sections of a computer.
Form factors and kinds of motherboards
Motherboards have evolved with computers. The numerous motherboard form factors are shown here, along with more information on each, including ATX, which is the most prevalent.
A motherboard has how many ports?
The number of ports, connections, and slots on a motherboard is determined by the manufacturer and model. Although there is no universal standard, most basic motherboards include at least two connections, four USB ports, and a handful of expansion slots. More information can be found in the handbook for your motherboard.
What is a laptop's motherboard?
Laptop motherboards are similar to desktop motherboards, although they are often smaller and thinner. In addition to laptops, mobile devices such as phones and tablets feature motherboards that house their CPUs and memory. Because these motherboards are susceptible to damage from falls, they must be handled with care.
What effect does a motherboard have on computer performance?
People who use computers for simple tasks such as browsing the Internet or composing emails will not notice a substantial difference between low-cost and high-cost motherboards that support the same components. Premium motherboards, on the other hand, include major features for enthusiasts:

A brief history of the motherboard
Long after the first computers, the modern motherboard was created. Early computers were simpler devices, lacking the need to coordinate several operations at the same time. There wasn't much need for mass-produced motherboards before the consumer market took off.
This changed in 1981, when IBM debuted the personal computer, which is why laptops and desktop computers are referred to as PCs. These computers need a method to control their activities for the benefit of consumers. As a result, IBM created the first motherboard that did it—a computer chip that handled all the minutiae while people accomplished their digital duties.
This component was originally known as a planar and went by numerous other names during its development. Because the circuit board served as the mother to all other computer components, the name "motherboard" became the most prevalent. As a result, motherboard extensions are frequently referred to as "daughterboards."
What kind of motherboard do I have?
- Press Windows + R on your keyboard to open the Run window.
- Enter msinfo32
- Enter your password.
- The name of your motherboard's manufacturer will appear next to "Baseboard Manufacturer."
- Next to Baseboard Product, you'll find the model name of your motherboard.
Why are the slots and connections coloured differently?
A motherboard's slots, ports, and connections may be colour-coded to help identify the type of slot, port, or connector. In our motherboard image, for example, the IDE connectors are different colours to help distinguish between the primary and secondary connectors. When the memory slots are coloured differently, it indicates that they are dual-channel, and pairs of memory should be installed on the same channel (colour). In our example, the yellow memory spaces are channel A, while the black slots are channel B. If you were just installing two memory sticks, you should put them both in Channel A (the yellow slots) for best performance.
Are Dell, HP, and other OEM motherboards all the same?
Yes, OEM motherboards from manufacturers like Dell and HP differ slightly from other motherboards available from retailers. An OEM creates a motherboard specifically for each type of computer. Some OEMs may even go so far as to make dramatic alterations that go beyond the standard motherboard form factor. Although an OEM motherboard may have variances, they frequently appear fairly identical cosmetically. Also, if not too many modifications have occurred, it may be easy to replace the OEM motherboard with a retail motherboard. For OEM PCs with variances, you'll need to get a replacement from the OEM or from a third-party that sells used computer components.
What should you look for in a motherboard?
Size: Motherboards are available in several form factors, such as ATX, Micro-ATX, and mini-ITX. Choose the appropriate size for your computer case.
Chipset:
Whether your CPU is made by Intel or AMD, you'll need a motherboard that supports the chipset and socket of your processor.
Overclocking:
If you're satisfied with stock clock performance, you don't need to invest extra money on a motherboard with overclocking capability. If you want to get more speed out of your processor, locate a suitable motherboard for tuning.
Expansion slots:
If you want to install graphics cards, sound cards, LAN cards, or SSD cards, look for a motherboard with many expansion slots.
What components make up a motherboard?
There are several motherboard designs and form factors that have been changed throughout the years to accommodate new devices and changing technologies. However, all motherboards share a few characteristics. They all feature circuitry for coordinating computer functions as well as a heat sink for absorbing and channelling heat to keep the motherboard cool while in use. Most feature a backup power supply as well.
When you look at any motherboard, the first thing you'll notice is that it has a lot of slots and connectors. Because everything passes via the motherboard, it must come into physical contact with practically all computer components. Main power, CPU, RAM slots, USB, PCI, video and sound cards, and expansion slots are all included.

If you use a wireless mouse or an external keyboard, they have their own connections, as do any other necessary accessories. This is why a motherboard resembles a ring of connections - it serves a single purpose.
The ports on a motherboard tend to vary throughout time, depending on what contemporary technology requires. This is why an old motherboard may have several dead ports for outmoded connections.
Those are usually peripheral ports. The motherboard manages internal connections such as RAM and CPU, as well as external interfaces such as USB and Thunderbolt. In addition, motherboards include networking ports (Ethernet, WI-Fi, or both) and video interfaces to support CPUs with integrated graphics.
The connections have evolved throughout time, but the purpose of a motherboard remains the same: it serves as a hub for your computer. The motherboard is linked to everything that connects to your computer in some way. The USB ports on the front of your computer case are also directly connected to the motherboard.
How do you upgrade your motherboard?
The motherboard is situated opposite the access panel in most computer cases, which open from the side. This protects the motherboard from most risks, and the vertical arrangement helps keep dust at bay. Another benefit is that it keeps all of your expansion slots easily accessible, and lying your computer on its side makes plugging in any new components a breeze.
Making sure your motherboard has all the connectors you'll need for your planned modifications might be a difficult undertaking. Many motherboard upgrades are required to allow additional enhancements, such as new GPUs or CPUs that were not supported by your prior model. This can get expensive. In the end, you may find that upgrading your motherboard was unnecessary in the first place.
If your motherboard is getting too old, consider purchasing a new PC. Many components, such as the RAM and CPU, are likely to require replacement. When all factors are considered, purchasing a new PC may be less expensive. Examine the prices and advantages to see what works best for your budget.
To upgrade the motherboard, you must disassemble your computer and replace every component except the power supply and hard drives. Everything is connected to the motherboard; therefore, everything must be removed if you want to upgrade it.
What is the structure of a motherboard?
Sockets on the motherboard house components such as CPUs, memory sticks, and expansion cards. Other components, such as hard discs, connect to a motherboard but are often housed within the computer chassis. On a motherboard, only compatible components will fit. An Intel processor, for example, will not fit on a motherboard built for AMD CPUs. Furthermore, a motherboard will only support a limited number of CPUs.

TPM 2.0 on motherboards: what is it?
TPM (Trusted Platform Module) is a tamper-proof mechanism for creating and storing cryptographic keys for encryption. TPM 2.0 is required by Microsoft for Windows 11 security to combat ransomware attacks and firmware breaches. Fortunately, most current motherboards include TPM 2.0 and can run Windows 11.
Is a motherboard present in a laptop, smartphone, or tablet?
Yes, albeit the board is generally referred to as a "logic board" rather than a motherboard. The logic board looks and functions similarly to a motherboard. Due to space constraints on most logic boards, components such as the CPU and RAM (in tablets and smart phones) are soldered onto the board. Furthermore, there are no slots or sockets like on a standard computer motherboard because many of these devices do not support upgrades.
