What is the function of Inter Frame Space ,or IFS?

Try not to be surprised if an interviewer asks you an easy technical question in the later stages of an interview. They may have already used all their more challenging questions, be convinced of your qualifications for the role, or are using an easy question to allow them to gather their thoughts and review their list for more difficult ones. Regardless of when you are asked a technical question or its complexity, make sure to keep your answer brief and to the point. The interviewer will always ask you a follow-up question if they need additional information.

"IFS or Inter Frame Space defines the minimum number of bits separating consecutive messages. It provides an intermission between two frames and consists of three recessive bits known as intermission bits."
