Packet Switching.
Cards in this deck (4)
- 1Packet switching. a mode of data transmission in which a message is broken into a number of parts which are sent independently, over whatever route is optimum for each packet, and reassembled at the destination.Advantages of packet switching.
traffic flow is efficient.
big files can be sent but don't clog network.
if one packet is lost the others are still safe. - 2Disadvantages of packet switching. if one or more packets are lost or corrupted during transmission,the whole file will not be received correctly.Simplex
signals go one direction at a time.
TV remote to the TV. - 3Full duplex. signals go in both directions at same time. speaking to each other on the phone.Half duplex.
signals go in both directions but not simultaneous. - 4Serial and parallel transmission. In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels. Parallel transmission. In data transmission, parallel communication is a method of conveying multiple binary digits (bits) simultaneously. It contrasts with serial communication, which conveys only a single bit at a time; this distinction is one way of characterizing a communications link.Benefit and limitation of above.
Full duplex is good due to because people can speak to each other at the same time and signals go in both directions.
Half duplex.
signals go both directions but are not simultaneous.
Simplex.
signals only go one way like a remote going tot the TV.
The best one I can think of is full duplex because you can talk and text to each other at the same time.
