The basic architecture of almost every computer system ever made is based on the stored program architecture designed
in 1945 design by the mathematician John Von Neumann
. He described a computer architecture where data and instructions would be stored in memory.
What is the purpose of the stored program concept?
The term Stored Program Control Concept refers to
the storage of instructions in computer memory to enable it to perform a variety of tasks in sequence or intermittently
.
What is the von Neumann or stored program architecture?
The Von Neumann architecture, also known as the Princeton architecture, is
a computer architecture based on
that described in 1945 by the mathematician and physicist John Von Neumann. … A stored-program digital computer is one that keeps its program instructions, as well as its data, in read-write, random-access memory.
What is stored program control concept?
The Stored Program Control concept is
where a program or a set of instructions to the computer is stored in its memory
and the instructions are executed automatically one by one by the processor. … A separate processor is used for the maintenance of the switching system.
What are the primary benefits of the stored program design?
The stored programme type would receive the same number of inputs and provide the same number of outputs as the wired type. However, the major advantage of the stored programme type of computer over the wired type is that
the control sequence can be changed comparatively simply by modifying the programme
.
What are the main features of von Neumann architecture?
The key elements of von Neumann architecture are:
data and instructions are both stored in primary storage
.
instructions are fetched from memory one at a time
and in order (serially) the processor decodes and executes an instruction, before cycling around to fetch the next instruction.
Why von Neumann architecture is still used?
| Bus Description | Control Bus Control Bus carries signals/commands from the CPU. |

What are the four main components of any general purpose computer?
A general purpose computer has four main components:
the arithmetic logic unit (ALU), the control unit, the memory, and the input and output devices
(collectively termed I/O). These parts are interconnected by buses, often made of groups of wires.
How is a program stored in memory?
When the CPU executes a program, that program is stored in the computer’s main memory (also called the RAM or random access memory). … The CPU executes a program that is stored as
a sequence of machine language instructions in
main memory.
What is Ram in memory?
Random access memory
(RAM) is a computer’s short-term memory, which it uses to handle all active tasks and apps.
Who gave stored program concept?
The idea was introduced in the late 1940s by
John von Neumann
, who proposed that a program be electronically stored in binary-number format in a memory device so that instructions could be modified by the computer as determined by intermediate computational results.
What are the features of stored program control?
The principle feature of stored program control is
one or multiple digital processing units (stored-program computers) that execute a set of computer instructions (program) stored in the memory of the system by which telephone connections are established, maintained, and terminated in associated electronic circuitry
.
What is stored in the program counter?
The program counter (sometimes called instruction pointer) is a special-purpose register that contains
the memory address of the next instruction to be executed
. Every instruction is fetched from external memory at the address in the program counter, and stored in the instruction register.
Where are important programs stored?
stored program A program that is stored
in the memory of a computer
. The execution of the program then requires the use of a control unit – to read instructions from the memory at appropriate times and arrange to carry them out.
How a stored program is executed?
Both instructions and data are stored in the memory of the computer. The instructions get into the memory by the execution of a special program known as the
loader
, which takes the output of the compiler and loads it into memory. … The IP contains the address of the next instruction to be executed.
What is the difference between von Neumann and Harvard architecture?
| VON NEUMANN ARCHITECTURE HARVARD ARCHITECTURE | Two clock cycles are required to execute single instruction. An instruction is executed in a single cycle. | It is cheaper in cost. It is costly than Von Neumann Architecture. |
