For HELLO to be seen on an output technology (the screen) the user would have to use an input technology (keyboard) to enter in those letters. Then, those letters will go through the processing technology containing the CPU. Inside the CPU the letters are decoded either by the ALU or controlling unit and then are contained in the system unit. When the letters go through the processing unit, they will be put into their ASCII code and declared their bit or byte number. After the letters go through this process then they will be able to be seen on an output technology.
