Im stuck on a question I was asked.
Id like to know the process taken by the PC to display a character from the keyboard to the word processing package say.
sent to the CPU
sent to memory
word SW reads memory
tells the cpu where to display on screen (x,y)
sends the command tot he display device
display device o/p the visual data to the monitor
that kind of thing is what im after.
Any help would be most appreciated,
