Detailed explanation-1: -How many clock pulses will be required to completely load serially a 5-bit shift register? Explanation: A register is a collection of FFS. To load a bit, we require 1 clock pulse for 1 shift register. So, for 5-bit shift register we would require of 5 clock pulses.
Detailed explanation-2: -In serial shift register number of clocks pulses required to enter a byte (8 bit) is 8 clock pulse.
Detailed explanation-3: -4-bit SIPO shift register needs 4 clock pulses.
Detailed explanation-4: -A 4-bit shift register requires 4 clock pulses to completely load or completely unload; 8-bit shift register requires 8 clock pulses, 16-bit 16 clock pulses and so on. Memory registers, when clocked, transfer data at parallel data inputs directly into register in one clock pulse.
