Sometimes it's not about typing.
In the electronics works the us a serial protocol called SPI Serial Peripheral Interface.
In schematics we might have a micro controller that connects to several sensors or memory chips on a pair of pins, 1 each for transmit and receive.
The micro controller is the master and the common nomenclature for the pin names is MISO and MOSI MasterInSlaveOut and MasterOutSlaveIn.
This overcomes confusion with regard to using things like TXD and RXD.
Wokeness has now suggested a bunch of alternatives.
PICO PeripheralInControllerOut and POCI... are the 2 leading alternatives.
Problem is I now have data sheets and schematics going back to the 1980s
It's bullshit to me.
Words can have more than one meaning.
Context and meaning matter.
I just want design cool electronics.
