General Discussion

Might wanna look it up.

Good thing I gave specific examples for you to address!


Neurons in my brain cause a nerve impulse to travel down my spinal cord and into my fingers. My fingers press on a keyboard, pushing down on a membrane below the keys. This action closes a circuit within the keyboard, which is interpreted by a chip within the keyboard. The key press is translated by another chip in the keyboard into a USB HID message indicating which key has been pressed. That is transmitted over a USB cable to the USB hub within the computer. The USB hub sends a signal to the keyboard driver, indicating that a key has been pressed. The driver sends a message to the operating system indicating a key has been pressed. The operating system sends a message to the active application indicating that a key has been pressed. The application notifies the rendering engine that a letter needs to be drawn at a specific location. The rendering engine passes that request to the operating system, which passes that request to the graphics driver. Which passes that request to the graphics interface hardware, which updates the frame buffer changing white pixels to black pixels in the shape of the appropriate letter.

Then the neurons in my brain start another nerve impulse down my arm and into my finger, causing my finger to rise off the keyboard. That releases the pressure on the membrane under they key, disconnecting a circuit. A chip within the keyboard detects the circuit has been cut, and signals the USB chip that a USB HID key released message needs to be sent to the computer. That key released message is processed by the USB hub within the computer, and sent to the keyboard driver, indicating that the key has been released. The driver sends a message to the operating system indicating the key has been released. The operating system sends a message to the active application, indicating that a key has been released.

After this process repeats many times (once for each letter), neurons in my brain send a nerve impulse down my arm, causing the muscles in my arm to move my hand over to the mouse, and then similar messages cause my arm to move the mouse. Optical recognition chips within the mouse detect that the surface of the desk has slightly moved. This information is relayed to the USB HID chip within the mouse, which transmits a "mouse moved" message to the USB hub within the computer. The USB hub sends a message to the mouse driver, indicating that the mouse has moved. The mouse driver sends a message to the operating system, indicating the mouse has moved. The operating system sends a message to the graphics driver, indicating that a particular arrow shape should be moved to a new position. The graphics driver sends that message to the graphics device, which updates the framebuffer with the new location of the arrow. It now obscures the "Post my reply" button that has been rendered by the active application.

Do you need me to continue with how clicks are handled, and how network stacks work? Or do you get the point yet that you not understanding something does not mean no one understands something?


I gave very specific examples. Try reading them.


No, you have no real clue. First, science is a methodology. It doesn't "know" anything.

Second scientists do have a very good understanding of how life started, and how life works. That's why your doctor isn't using leeches to treat you.


Again, you are not everyone. And your caricature of people you disagree with is not an accurate description.

But it's abundantly clear you are not asking your questions out of any desire to discuss anything. You are here only to insult and deride.
