Microprocessor If the number of address bits in a memory is reduced by 2 and the addressability is doubled, the size of the memory (i.e., the number of bits stored in the memory) Doubles Remains unchanged Halves Increases by 2^(address bits)/addressability Doubles Remains unchanged Halves Increases by 2^(address bits)/addressability ANSWER DOWNLOAD EXAMIANS APP
Microprocessor While using a frequency counter for measuring frequency, two modes of measurement are possible: Period time Frequency mode There is a ‘cross-over frequency’ below which the period mode is preferred. Assuming the crystal oscillator frequency to be 4MHz, the crossover frequency is given by 2 Mhz. 8 Mhz. 1Khz. 2 Khz. 2 Mhz. 8 Mhz. 1Khz. 2 Khz. ANSWER DOWNLOAD EXAMIANS APP
