Direction of Data Flow:
Communication between two devices can be Simplex,
half duplex, or full duplex.
Simplex:
In Simplex mode Data flow one side only In this type
device A send data to device B but device B not able to send data to device A.
In our daily life we use TV cable connection is an
example of simplex data flow.
Half
Duplex
In Half Duplex mode Data flow both sides. In this
type device A and device B send data to each
other but when “A” send some data device
“B”
not send data and when device “A” send data device “A” not send data.
In our daily life we see police man use wireless
phone/ walky talky is an example of Half Duplex data flow.
Full

In Half Duplex mode Data flow both sides. In this
type device “A” and device “B” send data
& receive data same time.
