motherboards do the same job but they are all different.

It is exactly different because one is bus and one is port. Video port is used to connect to monitor or LCD, but video bus refers to the bus on video card that works to transfer data. The same as motherboard, It has bus on itself to transfer data among connected devices.
Binary Data is transmitted on Data Buses.
normally the motherboard have 1 slot for video card.
The onboard video
A motherboard takes both input and output. For example, it may take inputs from a keyboard or mouse, and output video from an integrated graphics card. In a more general sense, the motherboard is the device which connects all of the pieces of the computer together; All of the data sent between devices is routed through the motherboard. In effect, every one of these data transmissions can be viewed as input and output (input data from one device to the mobo, output the data from the mobo to another device).
by studying the motherboard data sheet
Data travels on the motherboard through electrical signals transmitted via traces, which are conductive pathways etched onto the circuit board. These signals move between various components, such as the CPU, RAM, and expansion slots, using buses—sets of parallel or serial lines that facilitate data transfer. The speed and efficiency of data travel are influenced by the motherboard's architecture, including the types of buses used and the overall design. Additionally, signal integrity is maintained through careful layout and shielding to minimize interference.
Video cards receive data primarily from the computer's CPU (central processing unit) through the motherboard. The CPU processes instructions and generates graphics data, which is then sent to the video card via a high-speed interface, such as PCI Express. Additionally, video cards can access data from system memory (RAM) and onboard memory (VRAM) to render images and graphics for display.
Pixel shader technology is part of your video card and its drivers. Unless your motherboard has integrated video, it has nothing to do with pixel shader. If your asrock motherboard has integrated video, find out what kind of integrated video it has & post a new question with that info.
No, it isn't transmitted that way.
