Can be defined as a digital machine because the signals del monte meat are being handled, are electrical signals processing information through a system of binary values, and also as a synchronous machine as each activity is organized by a clock. It has an arithmetic logic unit (ALU), which has a capacity of numerical calculation and logical This controlled by programs, this feature is what differentiates a calculator, ie it can read, interpret and implement orderly. It communicates with the real world, by peripheral input and output operations, or analog form. So the computer is a versatile machine that is communicated del monte meat through programs, receive information, interpret, transform and provides information.
The architecture of the von Neumann model is based on the concept del monte meat of a stored program where it is proposed that the data were to be stored together in a common and uniform. This is called del monte meat memory. del monte meat The memory cells are ambiguous, del monte meat ie can act as data or instructions The moment you run the program del monte meat stored, it is determined which cells contain data and instructions.
With Rupture del monte meat Sequence, is called the "Conditional Jump" instruction which the computer depending on the result of the operation is executed or not instruction.
The Von Neumann machine comprises: a main memory central processing unit, CPU containing: UAL: Local arithmetic unit, UC: control unit, a set of records transfer del monte meat lines (buses) control and data memory address input / output
Main function: storing data and instructions that make up the program. The unit that handles are the cells, all of equal size, each identified by an address they can store both data and information.
Basic storage unit: bit. A memory cell can have up to n bits. A minimum size cell is composed of 1 byte which can store up to February 1 through 8 different values.
Coordinates all computer activity, which controls the processing cycle. When required to execute an instruction: the UC command unit recognizes it, loads the operating executes the instruction stores the results
The peripheral input / output interface with wiring, bus system, which is composed of the set of shared paths that allow the interconnection of the various components, CPU, memory and peripheral input / output.
