If you have an RF (Radio Frequency) signal of 1MHz and you modulate it with a signal of 1kHz you end up with three frequencies 1MHz - 1kHz 1MHz 1MHz + 1kHz The carrier is 1MHz. The lower side band is 1MHz - 1kHz or 999kHz while the upper side band is 1MHz + 1kHz or 1.001MHz kHz is thousand cycles per second MHz is million cycles per second

A superheterodyne receiver is a Radio Frequency receiver method that multiplies the received signal frequency with a local oscillator frequency to get frequencies that are the sum and difference of the 2 frequencies. For example, if the received signal is 5MHz and the local oscillator frequency is 4MHz, they are multiplied together. 1MHz and 9MHz frequencies would be gotten. Usually the 1MHz is the Intermediate Frequency (IF). It will be admitted (through a band pass filter) later passed through the required electronic circuits for proper processing. There is also the method of the Variable Tuned Filter.
Like many early microprocessors it has a 1mhz internal clock for its' operation. 12mhz is divided internally by 12 to derive this frequency.
MHz stands for Mega Hertz. Hertz or Hz is unit for frequency and is represented by inverse of time unit i.e. second(-1) i.e. 1/second or per second. Frequency = 1/ time period in seconds 1MHz is 10^6 or 1000000 Hz.
Yes.
It depends on the signal you are trying to receive. For instance, the AM frequency band lies around 500KHz to 1700kHz. Lets say you have a tuned amplifier such that the resonant frequency was set roughly in the middle of that band at 1000kHz (1MHz). AM radio stations typically space out their broadcasts 9-10kHz. So if Q=f_resonant/f_bandwidth the Q of a tuned amplifier with a bandwidth of 10kHz (which would be decent, maybe a little spill over), would be: Q=1Mhz/10kHz Q=100 The higher the Q, the greater the selectivity. Too high be a bad thing too.

1Mhz (full wave) or 500kHz (half wave) but you didn't describe any type of oscillation so therefore it has no frequency except a vibration. What does Vibration mean? A sound vibration, does that mean noise energy? A material shake, a high noise energy noise pitch from collision or hum?
1 GHz = 1,000 MHz.
