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 problems in designing a high quality oscillator is maintaining the output frequency at the value required. One method is to control it by a quartz crystal; this is cut so that it vibrates mechanically at the design frequency, and is coupled to the electronics by the piezo-electric effect.
A 12 MHz crystal oscillator is an electronic circuit, whose output frequency is controlled by a quartz crystal to repeat 12 million times per second.
(Note. Oscillators don't have to be electronic. Other examples are a guitar string, a Flute or a pendulum. An electronic oscillator is the only one that can be crystal controlled.)

Which oscillator is used in 8051?
crystal oscilators mostrly of 11.05.... or 12MHz are used with microcontrollers,
Why you use 12mhz in 8051 micro controller?
Like many early microprocessors it has a 1mhz internal clock for its' operation. 12mhz is divided internally by 12 to derive this frequency.
Why you use 11.0592mhz crystal in place of 12mhz in 89c51?
The 11.0592 MHz crystal is commonly used with the 89C51 microcontroller because it provides an exact frequency that allows for accurate baud rate generation for serial communication. This frequency is particularly useful as it enables the generation of standard baud rates such as 9600, 19200, and 115200 baud without introducing timing errors. In contrast, a 12 MHz crystal would not yield the same precision for these common baud rates, leading to potential communication issues. Thus, the 11.0592 MHz crystal is preferred for reliable serial communication.
