1, the computer is able to do the calculation?
1.1, the binary data
1.2, calculates with Boolean
1.3 realize Boolean operation circuit
All circuits can be calculated by the computer is such a circuit configuration.
2, already know
2.1, the circuit can complete the calculation, it is possible to design an addition, subtraction, multiplication ..., use them to complete the various types of computing.
2.2, calculate what needs to be done, a corresponding circuit design on the hands.
2.3, the design much better atomic circuit , when necessary we put them together. (ENIAC is to do so)
2.4, by some commands to control the computer, let the computer run in accordance with this command , this command can be an electrical signal, he said this is not a temporary command input to the computer, but stored somewhere, you can always change command changed, it will change the function of the computer. (EDVAC is like this, and now the computer is EDVAC) --- This model is stored program computer
3. What is a stored program computer (von Neumann computer)?
3.1, input devices
3.2, the operator: the data arithmetic and logic operations
3.3, the controller: controls the respective components of the unified command and coordination computer
3.4, memory: store intermediate results and information to be operated, and comprising machine instructions
3.5, output devices
