Von Neumann architecture is modern & common structure of a computer,\u00a0An IAS (Institute for Advanced Study) computer, it consists of 03 primary components<\/strong> : (1)<\/strong> Central Processing Unit (CPU) (2)<\/strong> Main Memory Unit (3)<\/strong> Input\/Output (I\/O) Device<\/p>\n

Central Processing Unit<\/strong><\/h6>\n
    \n
  • Central Processing Unit (<\/strong>CPU)<\/strong> consists of – (1)<\/strong> Control Unit (CU) (2)<\/strong> Arithmetic Logic Unit (ALU) (3)<\/strong> Registers, to process input store and output results.<\/li>\n<\/ul>\n
    Registers<\/strong><\/h6>\n

    (1) Accumulator<\/strong> : Stores the results of calculations made by ALU.
    \n(2) Program Counter (<\/strong>PC)<\/strong> : Keeps track of the memory location of the next instructions to be dealt with.
    \n(3) Memory Address Register (<\/strong>MAR)<\/strong> : It stores the memory locations of instructions that need to be fetched from memory or stored into memory.
    \n(4) Memory Data Register (<\/strong>MDR)<\/strong> : It stores instructions fetched from memory or any data that is to be transferred to, and stored in, memory.
    \n(5) Current Instruction Register (<\/strong>CIR)<\/strong> : It stores the most recently fetched instructions while it is waiting to be coded and executed.
    \n(6) Instruction Buffer Register (<\/strong>IBR)<\/strong> : The instruction that is not to be executed immediately is placed in the instruction buffer register IBR.<\/p>\n

    Differences Between Von Neumann and Harvard Architecture<\/strong><\/h6>\n
      \n
    • The main difference between both Architecture model is Von Neumann Architecture model stores both program data and instruction data in the same memory<\/strong> where Harvard Architecture model separates the storage and signal paths for data and instructions.<\/li>\n
    • SCADA & PLC<\/strong> – The primary difference between a SCADA (Supervisory Control and Data Acquisition) is software used in Von Neumann Architecture and PLC (Programmable Logic Controller) is hardware used in Harvard Architecture.<\/li>\n<\/ul>\n
      Flynn’s Taxonomy<\/strong><\/h6>\n
        \n
      • M.J. Flynn classified computer system\u2019s organisation based on the number of instructions as well as data items that are changed at the same time. There are 04 categories in Flynn\u2019s taxonomy :<\/li>\n<\/ul>\n

          \n
        1. SISD (Single instruction stream, single data stream)<\/li>\n
        2. SIMD (Single instruction stream, multiple data stream)<\/li>\n
        3. MISD (Multiple instruction stream, single data stream)<\/li>\n
