In practice, systematic sampling is used on account of its simplicity and convenience. It's easy to explain to the people doing the actual work.
It can be justified theoretically wherever the population from which units are to be sampled systematically are randomly distributed.
It can be used for sampling households, sampling callers on a telephone line, sampling plants along a transect in (say) a field, sampling people passing through customs, and so on.
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
You can't conduct startified sampling if there are no difinative groups, thus systematic sampling is more efficient if your data has no groups.
Disadvantages of systematic sampling: © The process of selection can interact with a hidden periodic trait within the population. If the sampling technique coincides with the periodicity of the trait, the sampling technique will no longer be random and representativeness of the sample is compromised.

Nothing! there the same

Random sampling is picking a subject at random. Systematic sampling is using a pattern to pick subjects, I.e. picking every third person.

Compare the efficiency of simple random sampling with systematic random sampling for estimating the population mean and give your comments.

Answer is Quota sampling. Its one of the method of non-probability sampling.
Sampling error leads to random error. Sampling bias leads to systematic error.

Circular systematic sampling is a random sampling method. An example is random sampling of households. Assume that a random number generator provides the number 49 as a starting point. Starting with the household that is 49 on the target list, every nth household on the list would be sampled until the desired sample size is reached
Stratified random sampling.
