Quizplus · Accepted Answer

The physical I/O level is responsible for managing the transfer of data between the computer system and external devices or networks. This includes the interpretation of signals, addressing, and timing of data transfer. Therefore, it is the primary interface with the environment outside of the computer system. The other options (logical I/O, basic I/O supervisor, access method) are all higher-level abstractions that build on top of the physical I/O level.
