EDVAC was produced using which of these concepts ?
packet routing
stored program
circuit switching
packet switching
Correct answer is B
EDVAC (Electronic Discrete Variable Automatic Computer) was produced using the 'stored program' concept. This concept is a design architecture for computers where the instructions to be executed by the computer are stored in the same memory that holds the data. 'Circuit switching', 'packet routing', and 'packet switching' are concepts related to network communication, not computer design
