title: What part of the computer renders text? Hardware or Software?
body: <p>For example, if i make a very simple bootloader that runs a "hello world" program (as the operating system), where is the graphical representation of the text processed.  The the GPU render the text, or the the hardware.  Is basic text input and output hard-coded in either the BIOS or processor, or is it integrated in assembly/programming langauge?</p>
