Types of Motherboards Complete Guide to Understand Motherboard

What is a Motherboard

A Motherboard, also known as the logic board of a computer, is basically a printed circuit board where most of the principal components of a computer are connected. It is the one that is responsible for maintaining the overall stability of your computer system. A motherboard provides connectivity and enables the communication between the CPU and all other hardware components of a computer system.

As a result, there are a lot of aspects you need to look for while purchasing a motherboard. Not only that, but there are multiple types of motherboards available in the market. Fortunately, they are designed to work with specific types of processors and memory. This is another reason you need to check for the compatibility of a motherboard based on the other hardware components present in your computer.

Types of Motherboards: Complete Guide to Understand Motherboard

Although the work of the motherboard is pretty much the same, you will come up with a different variety of them that are based on many other factors. Moreover, as motherboards are present in PCs, Laptops, and even smartphones, they come in a different physical state that varies according to the available space in devices.

Here are the different types of motherboards that came into existence until today.

1. AT Motherboard

AT stands for Advanced Technology. These motherboards were in great use during the mid-80s. However, users had a lot of difficulties installing new drives on these motherboards. Moreover, they were quite larger considering their physical dimensions ranging up to 13.8 * 12 inches. This made them incompatible to fight into the mini desktops or personal computers.

2. ATX Motherboard

It was introduced as an improved version that overcame all the problems that came with the AT Motherboards. ATX refers to Advanced Technology eXtended, which was introduced in the early 1990s and is still in use even today. The ATX motherboards are comparatively smaller in size than the AT motherboards. Besides, there are a variety of ATX motherboards that are used in the small boards today.

Moreover, they also introduced the interchangeability of the connecting components. This made it further easier for the users to connect the ATX motherboards to their computers.

3. LPX Motherboard

LPX or Low-Profile Extended motherboard later introduced came with some significant improvements over its predecessors. Firstly, all the I/O ports were placed on the backside making it more convenient to connect to. In addition, it also brought the riser card into action for the very first time allowing more slots and an efficient way to connect to the motherboard. However, the LPX motherboard lacked accelerated graphic port slots which indeed turned out to be its biggest disadvantage.

4. BTX Motherboard

In order to meet the rising needs of new technologies, the BTX motherboard was further developed. BTX stands for Balanced Technology Extended Motherboards. It was in great demand between 1990s to the mid-2000. BTX motherboards focused to meet the high power requirements of the user. However, it eventually caught up with heating issues while trying to solve the power requirement section.

5. Pico BTX Motherboard

Just as the term Pico suggests, these were comparatively much smaller than the BTX motherboards. In fact, it is much smaller than most of the present-day micro-sized motherboards. With physical dimensions of 8 * 10.5 inches, they are highly portable and easy to fit in even in the mini computers. However, the Pico BTX motherboards served all the needs pretty well despite their smaller size. They mainly share a common top-half of BTX along with two expansion slots. The Pico BTX motherboards were specifically designed for half-height or for the riser card applications.

6. Mini ITX Motherboard

The Mini ITX Motherboards were introduced in 2001 by VIA Technologies. It was basically developed with a focus to introduce a fan-less cooling machine with certainly a low power consumption architecture. And due to this very fact, it later became useful for the home theatre PC systems. Originally developed for use in small-configured computer systems, the Mini ITX motherboards became well known in the home theatre domain due to their low noise cooling system. It allowed better sound quality for this reason.

Components used in a Motherboard

As mentioned earlier, the motherboard itself is simply a printed circuit board but with a lot of other components embedded in it. Now, each of these components has some specific job that is essential for the proper functioning of the computer. Here are all the components used in a motherboard and their basic usage.

1. Power Connectors

Power connectors are mounted on the motherboards in order to receive power from the switched-mode power supply (SMPS). There are two types of power connectors that are used in the motherboards.

AT Connector: This connector was basically used in the older motherboards. It comes with 2 number 6 male pin connectors.

ATX Connector: The ATX connector consists of 20 or 24 female pin connectors. This connector is used in all the present-day motherboards.

2. SATA Connectors

SATA or Serial ATA is the SATA-I/O standard interface. This is a storage device interface that connects with the various consumer devices. It basically focuses on meeting the maximum performance and bandwidth demands of the Hard Disk Drive of a computer or any device.

3. IDE Connector

IDE stands for Integrated Drive Electronics. Here, IDE either refers to ports or cables that are utilized in order to connect hard driver/ optical drivers both to each other and to the motherboard as well. The main task of an IDE Connector is to interface the disk drives. There are basically two connectors. A 40-pin male connector is used to connect the IDE hard disk drive. On the other hand, the other 34-pin male connector is used to connect to the Floppy Disk.

4. Expansion Slots

Generally, an expansion slot refers to a printed circuit board that we can insert into an electrical connector to expand the functionality of the computer system. We can insert normal stuff like the network card, sound card, VRAM, etc. Here are some of the highlighted expansion slots you should know about.

  • PCI Express Slot: It is the present-day fastest component in any motherboard. It supports a full-duplex serial bus.
  • ISA Slots: The Industry Standard Architecture slot is used to install display cards or sound cards into the system. It is a 16-bit bus and is probably one of the oldest slots even in today’s world.
  • AGP Slot: AGP is the abbreviation for Accelerated Graphics Port. This slot allows us to install the graphics care.
  • PCI Slots: Peripheral Component Interconnect or PCI slots are specifically used to install add-on cards on the motherboard. They were even considered one of the most valuable components of the motherboard. However, these days PCI slots are almost outdated and obsolete. This is because new methods and protocols have replaced the traditional ways.

5. CPU Sockets

CPU sockets are the ones responsible for connecting the processor to your motherboard. It uses a series of pins to connect the processor. CPU sockets vary from device to device as you move from mainstream CPUs to high-end desktops for gaming or so. The best part about it is that since these pins are not soldered, they are easily replaceable.

6. CMOS Battery

CMOS refers to Complementary Metal Oxide Semiconductor. It is basically a 3.0-volt lithium-ion cell that stores the hardware configuration settings in BIOS. The life span of this battery varies according to the usage and the overall environment of the system. It generally lasts for a couple of years quite comfortably.

7. Memory Slot

This slot consists of the RAM which is an important component for the efficient functioning of a machine. Earlier motherboards had the Single Inline Memory module slots which is a 32-bit BUS.

However, the modern-day motherboards do not make use of the SIMM slot. Instead, they now use the DIMM or the Double Inline Memory module slots. DIMM can be better explained as a double-sided SIMM that is able to provide twice the data provided by a SIMM.

8. BIOS

As most of us know is the root that allows us to operate a computer. BIOS simply stands for Basic Input Output System. It is present in the form of a chip that is attached to the motherboard. It holds all the information about the motherboard and further assists to perform start-ups whenever we turn on the computer.

Conclusion

To put it simply, Motherboard is the core part of the computer where all the other important components lie. In other words, we cannot imagine a computer without a motherboard. All six types of Motherboards have been mentioned above.

Through this guide, our intention was to provide you with the basic knowledge about motherboard and its different components. Hence, let us know if it has been helpful, and feel free to comment below for more queries.
