6 t flip flops are needed ( to connected as in asynchronous counter), 1st t ff o/p freq will be same as i/p clk, 2nd t ff o/p freq will be half of i/p freq, and 3rd ones o/p freq is i/p freq divided by 4...... so the o/p freq of 6th ff will be i/p freq divided by 32.

Did we at one time call flip flops go-heads?
Yes I did! in the early sixties. I remember going to the neighborhood grocery store in So. Cal. and my mother purchasing a pair for 13-15 cents in summertime for all us kids.
What are differences between asynchronous counter and synchronous counter?
Synchronous CountersSynchronous counters typically consist of a memory element, which is implemented using flip-flops, and a combinational element, which is traditionally implemented using logic gates. Logic gates are logic circuits with one or more input terminals and one output terminal, in which the output is switched between two voltage levels determined by a combination of input signals. The use of logic gates for combinational logic typically reduces the cost of components for counter circuits to an absolute minimum, so it remains a popular approach.Clock PulseSynchronous counters have an internal clock, whereas asynchronous counters do not. As a result, all the flip-flops in a synchronous counter are driven simultaneously by a single, common clock pulse. In an asynchronous counter, the first flip-flop is driven by a pulse from an external clock and each successive flip-flop is driven by the output of the preceding flip-flop in the sequence. This is the essential difference between synchronous and asynchronous counters.Asynchronous CountersAsynchronous counters, also known as ripple counters, are the simpler type, requiring fewer components and less circuitry than synchronous counters. Asynchronous counters are easier to construct than their synchronous counterparts, but the absence of an internal clock also introduces several major disadvantages. The flip-flops in an asynchronous counter change states at different times, so the delays in changing from one state to another -- known as propagation delays -- add up to create an overall delay. The more flip-flops an asynchronous counter contains, the greater the overall delay.ConsiderationsTypically, asynchronous counters are less useful than synchronous counters in complex, high-frequency systems. Some integrated circuits react faster than others, so if an external event occurs close to a transition between states -- when some, but not all, the integrated circuits have changed state -- it may introduce errors into the counter. Such errors are difficult to predict because of the randomly variable time difference between events. Furthermore, propagation delays can make it difficult to detect, or decode, the output state of an asynchronous counter circuit electronically.
How fast supercomputer can perform calculations?
Most of the fastest 100 computers in the world can execute 5 Trillion (5,000,000,000,000) floating point operations per second (FLOPS) The new Fastest Supercomputer, the IBM Roadrunner, just achieved 1 PetaFLOPS (1 quadrillion - 1,000,000,000,000,000 computations per second in early June, 2008) The actual measured speed was 1.047 PetaFLOPS. However, it is still being built - and should achieve 1.7 PetaFLOPS by the end of 2008.

What should you wear the first day of 3rd grade?
It all depends on your style, if your casual, a cute top and skinny jeans with some flip-flops and earrings would be perfect. Your hair in a bun would look super stylish too. You'd be SUPER popular the first day of school! If your girly, a cute flowery top with a fluffy skirt, sandals, and a neckalace would look cute. Maybe your hair down with a flower clip. If your tom-boy, a baggy plain shirt, shorts, sneakers, and your hair in a ponytail. If your cozy, slippers or ugg's would be perfect, along with a plain shirt and sweat pants, your hair in a bun, preferably. probably some hair bands on you hands. :)

What are the uses of flip flops in computer?
Flip flop is a slang term for a bistable multivibrator, an electrical device which is stable in either one of two states. By using the binary number system, which consists of just two digits, zero and one, the flip flop can be used to process data. There are flip flops all through the Central Processor Unit, as well as in every other device attached to the computer.
What is the relationship between the number of states and the number of flip flops?
There probably is no relation.
How many flip-flops are needed in an up-asynchronous counter which can count up to 64?
6
How many maximum possible number of states in a clocked sequential circuit having 6 flip-flops?
The maximum number of possible states in a circuit with 6 flip flops is 26 or 64.
What is another name for flip flops?
A LATCH can be said as the another name of flip flop as the only difference between a latch and the flip flop is that a latch is an level triggered device where as flip flop is an edge triggered device .
