Quizplus · Accepted Answer

In ATM (Asynchronous Transfer Mode), the basic transmission unit is a fixed-length packet called a cell. Each cell is 53 bytes long and includes a 5-byte header and a 48-byte payload. This fixed length ensures faster transmission and eliminates the need for additional header information, which saves bandwidth. Therefore, the correct choice is B) cell.
