frequency is simply the rate at which something is happening, ie the frequency of Christmas is once a year, the frequency of having breakfast is once a day etc. If frequency is expressed in Hertz, it's how many times something happens during a second.
Sampling is, well, sampling. Usually means testing and measuring something changeable. If you're running a bath and occasionally stick your fingers in to check the temperature, then that's sampling,
Sampling frequency simply describes at which rate you're making whatever test or measurement it is you're talking about.
What else can I help you with?
What Steps to take when selecting a suitable sampling frequency?
The Nyquist Theorem says that the sampling frequency should be twice the bandwidth to avoid aliasing. Thus if the bandwidth of the system is bw then the sampling frequency f=2*bw.
If sampling frequency doubles then quantization noise?
reduces
What is frequency offset?
the difference between the source freq. and the reference freq
What is the difference between a high frequency UPS and a Low frequency UPS?
The difference is in sine wave generation algorithm. In HI freq - it is 30kHz signal, modulated by 50Hz.
What is the highest sampling rate if the input frequency is 3 kHz?
According to Niquest Theorem, it has to be more than twice the input frequency.
What is the difference between quota sampling and cluster sampling?

What is the difference between random sampling and non random sampling?

What is the relation between sampling frequency and wave frequency?
There is no factual relation between these, but there is a common rule known as the Nyquist-Shannon theorem, that states that to reproduce a waveform with only reasonably errors, the sampling frequency must be at least twice the wave frequency.
What is the difference between simple random sampling and random sampling?
Simple!
What is the difference between a sample and sampling?
sample is a noun and sampling is TO sample(verb)
State sampling theorem?
sampling theorem is defined as , the sampling frequency should be greater than or equal to 2*maximum frequency, and the frequency should be bounded.. i,e fs=2*fmax where fs= sampling frequency
What is the relationship between sampling rates and frequency of the modulating signal when using pulse modulation?
The sampling rate must be at least double the highest frequency component of the modulating signal in order to avoid frequency aliasing.
What is differences between convenience and incidental sampling?
The difference between convenience and incidental sampling is that convenience sampling chooses the easiest people to reach when a sampling is done, whereas incidental sampling is done at random.
What is the difference between Sampling error vs sampling bias?
Sampling error leads to random error. Sampling bias leads to systematic error.

What is the ideal sampling frequency?
Not less than double the highest frequency component of the signal you're sampling.
Differences between probability samplingand non-probability sampling?
the difference is just that non-probability sampling does not involve random selection, but probability sampling does.
