title: How a 4 bit CPU Works on infinite data and recall that data from memory?
body: <p>Consider, a processor with only 4 transistors. It can represent only one nibble at a time. we need to work on data consist of 32bits (correction: i removed "infinite bytes" from here). how it can save? so that we input second nibble and so on.... and how we recall saved data? and also explain when we represent binary to octal or decimal, which cpu unit do this representations? </p>
