Suppose a researcher created a list of the names of everybody in a population of interest and selected every 10th name in order to get a list of participants comprising the sample. This type of sampling is called

Choosing every 10th name from an ordered list after listing the whole population is systematic sampling.

The fixed interval, here 10, is the sampling interval applied throughout the frame.

Quota sampling fills preset quotas of subgroups by non-random selection.

Simple random sampling gives every member an equal, independent chance, without any fixed interval.

Convenience sampling takes whoever is readily available, not an ordered kth selection.

A random start within the first interval keeps systematic sampling close to random selection.
