  == How's my 0100111000111 get through ==  I just wondered how my 01001101100111 got through in my machine.  software level is too logical to improve understanding on computer  so, I decided to explore the process on the sample working such as how inputting key 'c' is displayed through the machine. is it like this? keyboard port...BIOS...maybe CPU...MEMORY etc....  signal 'c' 's mapped basically 0x43 in ascii table, and I'm not sure in this time, anyway 0x43 or 0100 0011 code will go through machine and finally will be displayed on to my display device by 'c'.  ===from now on the key 'c' is probing into!!!===   ===reference gathering===  *Transistor :for more information about Transistor, click and glance it. meaningful on this
