twisted pairs
Cards in this deck (9)
- 1Simplexsimplex. Refers to transmission in only one direction.
- 2Full duplexFull-duplex data transmission means that data can be transmitted in both directions on a signal carrier at the same time.
- 3Half duplex(of a communications system or computer circuit) allowing the transmission of signals in both directions but not simultaneously.
- 4Serial and parallel transmission description.serial transmission and parallel transmission. Serial data transmission sends data bits one after another over a single channel. Parallel data transmission sends multiple data bits at the same time over multiple channels.
- 5benefits and limitations of simplexOne benefit is that it works straight away but a limitation is that you need to replace batteries more than you think.
- 6benefits and limitations of full duplexYou can both speak at the same time but you both can annoy each other by speaking at the same time.
- 7benefits and limitations of Half duplexYou would have to be in a zone to be able to speak to each other and you wouldn't get to speak at the same to you would have to wait till one stops speaking and then you can click the button to speak.
