Clock

Clock is the heart of any electronics hardware device that calculates,provides delay etc.Clock is essential in every hardware that needs a repetion like generating a ramp wave in multimeter, increasing or decressing a speed of processor, It is use almost in every device.

Clock is given using crystal oscillator, cmos ic etc.

Clock can be understanded better by student and bell example in schools

In Processor Clock impacts speed in following ways

---Raising a clock

---Dividing a clock by some factor (>1 i guess) i guess---gives more no. of cycles(Combination of each tick(1) tack(0) is known as cycle)-->fasten the speed

---Multiplying a clock by some factor (>1 i guess)---gives less no. of clock cycles (I guess if multiplication factor is greater than 1.obviously ! if it is less than 1 then it would indirectly be a division ...decimal removed ..no go down ...lab ! lab!. --> ultimately in these as time period increases therefore,no of clocks come after huge huge interval -->and thus speed reduces.

there are also many other factors to increase speed of processor beside clock like

--Pipelining
--Parllelism
--Increasing Cores of CPU
--Increasing No.  of bits like make a 64 bit ......the advantage of this reflects in high end graphics games....and not much in small programs....that is by increasing number of bits you mean to increase the data rate at a fix interval of time
