Von neuman architecture

VON NEUMAN
ARCHITECTURE
Introduction :
It explains the basic structure, including the CPU,
main memory, and input/output devices. The
video details the components of the CPU (control
unit, ALU, registers) and different types of
registers (accumulator, program counter, MAR,
MDR, CIR, IBR). It also touches on the roles of
address, data, and control buses, as well as the
functions of input and output units.
It is also known as the von Newmann model


Von Neumann architecture consists of CPU,
memory, and I/O devices.
The CPU includes a control unit, ALU, and various
registers.
Different registers like accumulator, program
counter, MAR, MDR, CIR, and IBR serve specific
functions.

, Address, data, and control buses facilitate
communication between components.
The von Neumann bottleneck limits processing
speed due to sequential instruction execution.
The concept of computer architecture,
distinguishing between fixed-program computers
and stored-program computers. It then focuses on
the von Neumann architecture as a fundamental
model for stored-program computers.


Basic Structure: Von Neumann
Architecture

The von Neumann architecture comprises three
main units: the central processing unit (CPU), the
main memory unit, and input/output devices. The
CPU is the core processing component, the main
memory stores data and instructions, and
input/output devices facilitate interaction with the
external world.
