Where can a crystal oscillator be used?
Any where a stable desired frequency is needed. Crystal Oscillators are quite accurate, they are used in computers as well as wrist watches.
They use a mechanical oscillatory force that is induced by an electric charge on a piezoelectric substance at resonance.

difference between local oscillator and controlled oscillator
Piezo-electric quartz crystals are used to define the frequency in a crystal-controlled oscillator. Quartz is a hard material that tends to oscillate mechanically at a high frequency (up to about 20 MHz) when maintained by the maintaining amplifier. The signal produced is far more stable and predictable than an L-C oscillator, especially when the crystal is placed in a dedicated oven with a controlled temperature.
microprocessor's speed is determined by its clock rate. is normally determined by the frequency of an oscillator crystal . Typically a crystal oscillator produces a fixed sinusoidal waveform. <microtask>
The oscillator provides the basic clock of a microcontroller to be able to execute the instructions in a stable, periodic way. It is often used for other peripherals too, like timer, UART, etc. as frequency base, usually divided by a clock divider for integer factors, or by PLL for rational factors. If the timing accuracy of these functions is not important, a simple RC oscillator can be used. Many microcontrollers have it internally. Accuracy is… Read More

Usually the crystal in the oscillators are composed out of Quartz.
A crystal oscillator is an electronic circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency. This frequency is commonly used to keep track of time (as in quartz wristwatches), to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters.
to have good frequency stability in oscillators
When a mechanical pressure or load is given to optic axis of the piezoelectric crystal, it develops equal and opposite charges on the mechanical axis of the crystal. This is called piezoelectric effect. Vice versa effect is called inverse piezoelectric effect. This principle is used in piezoelectric oscillator, where a changing voltage across the crystal causes it to change size, which in turn creates a counter voltage which opposes the voltage and creates a feedback… Read More

Your quartz watch, your cell phone, all electronics that uses a computer inside. The quartz crystal forms the time base for the digital pulses. Crystal oscillators are also used in radio receivers and transmitters to provide accuracy in frequency selection. In a transmitter it provides the exitation frequency. In the receiver it provides the local oscillator in a superhetrodyne setup. Multifrequency devices (tunable and channelised radio) take the local oscillator and multiply and divide it… Read More

An oscillator is something that produces an output that repeats regularly. In the electronics field this will be an electrical waveform, often but not always a sine wave. The most important property of an oscillator is its frequency : the rate at which the output repeats. This is measured in Hertz (Hz for short). One Hertz is one repetition (aka cycle) per second. One MegaHertz (MHz) is one million repetitions per second. One of the… Read More

A Wein Bridge Oscillator is a oscillator which is used for the measurement of Audio Frequency.
Internally two crystal oscillator cycles are used as one single cycle. During one single crystal cycle it is made to logic high and logic low in next cycle so, that 50% duty cycle is maintained.
The oscillator which is blocked by using transformer is called a blocking oscillator. Generally, the primary is given to the base and secondary is given to the collector of the transistor used in the oscillator circuit.

An amplifier can become and oscillator by adding positive feedback from the output back to the input. Positive feedback means that the phase of the signal fed back to the input is the same as the phase of the output signal. In the case of a high frequency oscillator, a tuned circuit (inductor and capacitor) or a quartz crystal in the input circuit will determine the frequency of oscillation.
Heat variances will cause the frequency to oscillate up and down in a rather dramatic way sometimes. Other possible crystal problems are manufacturing/quality-control error, aging, or vibration. Also, the oscillator circuitry can cause the frequency to vary. Crystal manufacturers specify circuit capacitance and circuit resistance values that must be used for correct operation. Incorrect circuitry can also set up unwanted overtone resonances or spurious frequencies.
An amplifier becomes an oscillator when positive feedback is applied. It is the simple way to do it.
RC phase shift oscillator is used to generate frequency in audio range and it is a fixed audio frequency oscillator where as wien bridge oscillator is a variable audio frequency oscillator for high frequency oscillations it is better to design wide band amplifier with LC network

A local oscillator is used in a superheterodyne radio circuit for example.The incoming radio frequency is mixed with an internal local oscillator circuit to generate a new intermediate frequency (IF) .The local oscillator usually runs at a frequency of 470kHz and is generated by an inductor and capacitor(LC oscillator)

Difference between oscillator and transistor
Yes. In older systems, the clock crystal speed either provided the direct clock for the front side bus, and everything else ran on a divider, or was double the speed of the front side bus. Modern systems use a single fixed crystal at 14.318 MHz, and everything runs at either a multiple or divider of that clock. Some components, such as network cards may have their own crystal. Most add-on cards also have an oscillator… Read More
A quartz clock is a clock that uses an electronic oscillator that is regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks are at least an order of magnitude more accurate than good mechanical clocks. Generally, some form of digital logic counts the cycles of this signal and provides a numeric time display, usually in units of hours, minutes, and seconds. Since… Read More
