Intel 4004

The Integers We Use In Programs Are Just So Small …

--

Our microprocessors started off with 4-bit registers (the mighty 4004 processor), and where we organised our memory in address with 8 bits in each. We then saw the development of 8-bit (8080), 16-bit (8086), 32-bit (80386) and 64-bit (Pentium) processors. Each of these processes could deal with larger integer values. Thus we end up with integers represented by 8-bit (byte), 16-bit (short), 32-bit…
