 It is a unidirectional type of Transmission mode.
 Only one of the two devices on a link can transmit and the other can only
received the data.
 Eg.: Mouse, Keyword, Monitor etc.

2. Half Duplex / Duplex Mode
Program Name: MCA
 In this mode, each stations can both transmit and receive, but not at the same
time.
 When one device is sending, the other can receive and vice versa.

3. Full Duplex Mode
Program Name: MCA
 In this mode, each stations can both transmit and receive at the same time.
 Full duplex mode is used when communication in both directions is required all the
