Question

What is the key idea behind the von Neumann architecture? To what
extent do modern computers conform to this architecture?

Answer 1

The modern computers are based on a stored-program concept introduced by John Von Neumann. In this stored-program concept, programs and data are stored in a separate storage unit called memories and are treated the same.

Answer 2

Answer:

The key idea behind the von Neumann architecture :

The Von Neumann architecture consists of a single shared memory for programs and data, a single bus for memory access, an arithmetic unit, and a program control block. The Von Neumann processor takes charge and discharge cycles seriously.

Modern computers confirm to this architecture:

The Harvard architecture has two separate memory spaces dedicated to program code and data respectively, two corresponding address buses and two data buses to access the two memory spaces. The Harvard processor offers parallel loading and execution.The basic principle of the Von Neumann architecture is that the sequence of operations used is stored in the same memory as the data, as a result of which he can change his own program. It gets interesting when you think about modern configurations with extensive microprogramming used to execute program commands. This becomes very difficult when vulnerability to hacker intrusion has to be considered. Defending against hidden backdoors at the heart of the system is a daunting challenge.
