Von-Neumann Architecture:-

                         Von-Neumann Architecture:

                 Von-Neumann proposed computer architecture design in 1945 which was later known as Von-Neumann Architecture. It consisted of a Control Unit, Arithmetic, and Logical Unit (ALU), Register and Inputs/Outputs.

 

            Von-Neumann architecture is based on the stored-program computer concept, where instruction data and program data are stored in the same memory. This design is still used in most computers produced today.

            A Von-Neumann-based computer: 

• Uses a single processor 
•  Uses one memory for both instructions and data
•  Executes programs followings the fetch-decode-execute cycle  

 

            Components of Von-Neumann Model:

•  Central Processing Unit  
•  Buses
•  Memory Unit
