During an interview, you will be asked to describe the different components of a computer system, operating systems, software applications, or network hardware. The interviewer will request this to test your technical expertise and understand how well you understand the IT systems you support. This particular question is relatively basic, and every technical support engineer should be able to respond to it. Other questions may be more complex or deal with components that you are unfamiliar with or don't have experience with. It would be best if you never tried to fake an answer or ad-lib. If you are not familiar with something, admit this to the interviewer, and then describe how you would gain the knowledge needed to support a particular piece of equipment.
