What is a motherboard?
Often referred to as the “backbone” or “spine” of the computer, the motherboard is the central circuit board. It functions as an essential platform for integrating and connecting different hardware parts. The motherboard, which is easily recognized as the biggest board inside the computer casing, is responsible for enabling communication between the CPU, RAM, expansion cards, and other peripheral devices.
The motherboard is made up of a non-conductive base made of plastic and thin copper or aluminum foil traces that form circuits connecting its parts. These circuits are connected to sockets for hard drives, disk drives, front panel ports, and slots for the CPU, RAM, and expansion cards. Additionally, the motherboard includes ports for external connections to devices like monitors, keyboards, and mice. In essence, the motherboard functions as both the structural foundation and the operational control center of a computer system.
A few names of the motherboard
In the dynamic realm of technology, a motherboard goes by several monikers, reflecting its fundamental role. It may be referred to as the “MB,” “mainboard,” “backplane board,” “main circuit board,” “base board,” “planar board,” “system board,” or even a “logic board.” This array of names attests to the motherboard’s centrality and diverse functions in facilitating the synergy of a computer’s vital organs.
Who found the motherboard?
The concept of the motherboard, in its evolution from earlier computing components, doesn’t have a single individual credited with its invention. The motherboard, as we know it today, evolved from a device called a backplane. The Planar Breadboard, designed by IBM engineer Patty McHugh in 1981 for the IBM Personal Computer, is considered one of the earliest instances of a backplane qualifying as a motherboard. However, the development of the motherboard was a collaborative effort over time, influenced by advancements in technology and the needs of the emerging computer industry.

What is the concept of 1st motherboard?
The backplane idea was developed first, which is where the motherboard originated. Each component of a computer system had its separate circuit board in the early days of computing. These boards connected to a backplane, which served as an electrical connector to facilitate communication between the computer’s parts.
The transition from this backplane setup to the first motherboard, the Planar Breadboard in 1981, marked a significant shift. The Planar Breadboard integrated essential components onto a single board, including a 4.77 megahertz microprocessor, 16 KB of memory, and connectors for peripherals like a keyboard and cassette tape for data storage. This marked a departure from the previous modular approach, streamlining the design and paving the way for the modern motherboard as a central hub that houses and connects key components within a computer system.
How has the motherboard evolved?
From their initial backplanes, motherboards have developed into smaller, more integrated designs. Notable turning points were the introduction of the advanced technology (AT) motherboard in 1984 and the Baby AT (BAT) motherboard in 1989. These days, expansion cards are frequently not needed for networking, audio, or video because motherboards are so highly integrated.
What role does the BIOS play on a motherboard?
The motherboard contains firmware known as the BIOS (Basic Input/Output System), which serves as the “brain” of the computer. It performs a power-on self-test (POST), initializes hardware at startup, and controls data transfer between the operating system and external devices. Using the BIOS, users can change system settings and obtain hardware information.
