What is meant by clock pulse in computer organisation?

Answer 1

the timing of all registers in the basic computer is controlled by a master clock generation.the clock pulses are applied to all flip-flops and registers in the system,including the flip-flops and registers in the control unit.the clock pulses donot change the state of register until it recieves an signal from control unit,these control signals are generated in control unit and provide control inputs for multiplexers in common bus to choose a particular process register!

Answer 2

A clock pulse is one cycle of the system clock. Some processors (such as the 8085) use that as their primary clock. Others, like the more advanced (current) Intel chips, internally multiply the clock to generate an internal clock at a higher speed.

Each instruction is executed in one or more clock pulses, depending on the instruction and on the processor. The minimum instruction time, for instance, for the 8085 is 4 clock cycles. The maximum, for some of the repeated string operations on an advanced processor, could be thousands.

Access to memory is also controlled by the external clock. In the 8085, 3 clock cycles are required to read or write one byte. In the advanced processors, 2 clock cycles can read or write 8 or even 16 bytes at a time.
