  5. Data Flow in Communication cont. • Half-Duplex:two-way alternate. Walki-Talki • Each side maybe sender or receiver but not a same time. In different time

  6. Data Flow in Communication cont. • Duplex: two-way concurrent. Computer network Mobile Network • Each side sender and receiver at same time. At same time
