I've made this circuit for an easily understanding of computers.
I know my English it's kind of awful but that's it.
How you can see i've divided the circuit in sectors.
The first sector (upper left corner) is the CLOCK it produces a static frequency to drive the cpu usually this frequency is around 3Ghz.
The second sector is the famous CPU it works by receiving inputs (the buttons) and sending outputs in binary
In this case it's a simple counter.
The third sector is the power supply it gives energy to the computer.
The fourth sector (down left corner) is the GUI (graphical unit interface). Remember that the cpu outputs binary codes and the gui converts them to drive a display a printer some computer speakers ecc. In this case it converts binary number to drive a 7 segment display.
The fifth sector is the display but it can be a printer ecc.
The last sector contains the inputs (in this case some buttons) in real life they can be a scanner a mouse ecc. (The buttons are in order :count down, count up, on, off)
Hope this helps a bit ;-)
