In digital logic and computing, a counter is a device which stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock signal.
In electronics, counters can be implemented quite easily using register-type circuits such as the flip-flop, and a wide variety of classifications exist:
Each is useful for different applications. Usually, counter circuits are digital in nature, and count in natural binary. Many types of counter circuits are available as digital building blocks, for example a number of chips in the 4000 series implement different counters.
Occasionally there are advantages to using a counting sequence other than the natural binary sequence—such as the binary coded decimal counter, a linear feedback shift register counter, or a Gray-code counter.
Counters are useful for digital clocks and timers, and in oven timers, VCR clocks, etc.
An asynchronous (ripple) counter is a single JK-type flip-flop, with its J (data) input fed from its own inverted output. This circuit can store one bit, and hence can count from zero to one before it overflows (starts over from 0). This counter will increment once for every clock cycle and takes two clock cycles to overflow, so every cycle it will alternate between a transition from 0 to 1 and a transition from 1 to 0. Notice that this creates a new clock with a 50% duty cycle at exactly half the frequency of the input clock. If this output is then used as the clock signal for a similarly arranged D flip-flop (remembering to invert the output to the input), you will get another 1 bit counter that counts half as fast. Putting them together yields a two-bit counter:

Plot: Giulio and Francesco Ferretti are two young twins, with a harsh childhood. They lived among scary and twisted folks' beliefs. Because of a too apprehensive and catholic mother, an absent father and a mysterious physical anomaly, Giulio, the most quiet between the two brothers, heads away from his family, having no desire of being in touch with the rest of the world. Francesco seems to suffer Giulio's departure and becomes nervous and unbearable . It's a radical changing in their lives, that gets worse because of the discovering of a secret involving their birth, a secret that leads the twins to confront themselves with the darkest human side. A secret that seems related to the murders commissioner Vanni is trying to solve. It's something that link Giulio and Francesco to the legend of VERSIPELLIS. While Vanny is searching for the truth in the streets of a dark Rome, the two brothers start hunting for each others, moved by a wild instinct. Giulio, Francesco and Vanni will have to go through a difficulties and pains, legends, foolishness and violence.

Plot: In this television show for babies, the four colourful Teletubbies coo and play in idyllic Teletubbyland. They repeat fun, infant-pleasing activities such as rolling on the ground, laughing, running about, and watching real children on the televisions on their bellies. Mysterious pinwheels and telephones rise out of the meadow to loosely direct the day's activities. The Sun, featuring a baby's face, comments on the proceedings with baby noises, and it rises and sets to begin and end the show.

Plot: This Martin Scorsese film depicts the Janus-like quality of Las Vegas--it has a glittering, glamorous face, as well as a brutal, cruel one. Ace Rothstein and Nicky Santoro, mobsters who move to Las Vegas to make their mark, live and work in this paradoxical world. Seen through their eyes, each as a foil to the other, the details of mob involvement in the casinos of the 1970's and '80's are revealed. Ace is the smooth operator of the Tangiers casino, while Nicky is his boyhood friend and tough strongman, robbing and shaking down the locals. However, they each have a tragic flaw--Ace falls in love with a hustler, Ginger, and Nicky falls into an ever-deepening spiral of drugs and violence.

where do you see yourself?
answer this question
are you residing amongst the introverts

behind enemy lines? covert
all this has been felt
continued to complain
outlining the frames
converted into saturated spores
this truth deranged
is your faith restored?
inaccurate
more so than before
CHAPTER TWO
fertilize the ground
that cultivates your assets
symbols of excellence
i will secure thyself against the caskets
rest not
the dwell within must grow
persecution
