Assertion (A): An instruction cycle consists of fetch and execute cycles.

Reason (R): Fetch cycle has one machine cycle but execute cycle may have one or more machine cycles depending on length of instruction.

1. using thin gate oxide
2. reducing the substrate concentration
3. increasing the substrate concentration.

Assertion (A): In C arithmetic operations are pemiissible on ints, floats and chars.

Reason (R): In C every arithmetic operator must be written explicitly.
