Microprocessor
Assertion (A): Negative values of incremental operator in DO loop are allowed in Fortran 77 but not in earlier versions of Fortran. Reason (R): Fortran 77 has better array facilities than earlier versions of Fortran.
Both A and R are correct and R is correct explanation of A
A is correct R is wrong
A is wrong R is correct
Both A and R are correct but R is not correct explanation of A
The DMA control waiting for the microprocessor to finish execution of the program and then takes over the buses
Data transfer takes place between the I/O device and memory during every alternate clock cycle
While the microprocessor is executing a program an interface circuit takes over control of address, data, control buses when not in use by microprocessor
DMA controller taking over the address, data and control buses while a block of data is transferred between memory and I/O device
