Microprocessor Assertion(A): Monostablemultivibrators (IC74121) are used in a microprocessor based system for frequency measurement. Reason(R): Microprocessor counts the number of interrupt signals/second or within a specified interval through ISR. A is false but R is true. Both A & R are true and R is the correct explanation of A. A is true but R is false. Both A & R are true but R is not the correct explanation of A. A is false but R is true. Both A & R are true and R is the correct explanation of A. A is true but R is false. Both A & R are true but R is not the correct explanation of A. ANSWER DOWNLOAD EXAMIANS APP
Microprocessor In a microcomputer , the address of memory locations are binary numbers that identify each memory circuit where a byte is stored. If a microcomputer uses 20-bit address, then numbers of different memory locations are 20 220-1 220 - 1 220 20 220-1 220 - 1 220 ANSWER DOWNLOAD EXAMIANS APP
