computer architecture is still referred to as
von Neumann architecture.
Besides, Von Neumann made two main
improvements. One is that the program
instructions and data are both stored in
memory while being processed which is
known as the stored program concept. The
other is binary processing of data which
simplifies the design of computer.
The above contents are the reasons that the
Von Neumann model is essential in
understanding computers.

The Little Man Computer (LMC) is an
instructional model of a computer, created
by Dr. Stuart Madnick in 1965. It models a

features of a modern computer. But the real

more variant types.
