It can be but it is not simple random sampling.
Yes, if under simple random sampling there are likely to be too few representatives from a certain subset of the population in which you might have an interest.

Hi, 1.The main advantage of Systematic sampling over simple random sampling is its simplicity. It allows the researchers to add a degree of system or process into the random selection of subjects. 2.Another advantage of systematic random sampling over simple random sampling is the assurance that the population will be evenly sampled. Disadvantage The process of selection can interact with a hidden periodic trait within the population.
