The customers that buy a new computer and receive a survey in the mail about the performance of the computer after one month are called respondents.
They are called respondents because they took part in a survey or poll about the performance of the computer they bought a month ago. Statistically, not everyone that got the mail took part in the poll, those ones are called non respondents, while the ones that took part in the survey are known as respondents.
