Simplex, half duplex and full duplex data transmission
Cards in this deck (7)
- 1SIMPLEX DATA TRANSMISSIONThe data signals going in only one way. An example is a remote control sending signals to a television.
- 2HALF DUPLEX DATA TRANSMISSIONThe data signal go in both ways but not at the same time. An example of this is in "walkie- talkies" as one person has to wait for the other to finish talking before he can speak.
- 3DUPLEX (FULL DUPLEX) DATA TRANSMISSIONThe data signals go in both ways at the same time. For this reason it is called bi- directional. An example is of this is seen in mobile phones as everyone can speak at the same time.
- 4SERIAL DATA TRANSMISSION MODEThe bits of data are transferred one at a time over a wire.
- 5BENEFITS AND LIMITATIONS OF SERIAL DATA TRANSMISSIONBenefit:
- Good Distances over a large distance.
Limitations:
-Complex because data has to be broken down into individual bits. - 6PARALLEL DATA TRANSMISSION MODEThe bits of data are transferred simultaneously over a wire- a whole byte can be transferred at the same time.
- 7BENEFITS AND LIMITATIONS OF PARALLEL DATA TRANSMISSIONBenefit:
- Faster because more bits are transferred per second.
Limitation:
- Shorter distance, maximum about 5 meters.
