What is serial transmission?
Serial transmission is a method of transmitting data where one bit is transmitted after another in a single wire. Serial transmission is usually used to transmit data between two computers as it is less expensive, yet at a cost of a slightly slow speed. A minimum of two wires is needed for serial transmission, which is less compared to a minimum of eight wires in parallel transmission. Serial transmission is used to send data over long distances as the bits are less likely to get out of order. It is used in devices such as modems, bar code readers and light pens .
What are two types of transmission to transfer data on a bus?
serial and parellel transmission
A transmission method that allows one node to send data to a defined group of nodes?
Multicasting is a transmission method that allows one node to send data to a defined group of nodes.
What is simplex communication?
half-duplex communication of a data transmission method
What is packet oriented data service?
A method of data transmission in which small blocks of data are transmitted rapidly over a channel dedicated to the connection only for the duration of the packet's transmission.
Which communication is faster in parallle and serial?
Parallel data transmission is faster compared to serial data transmission. The speed of a parallel link is equal to the number of bits sent multiplied by the bit rate of each individual path.
Which switching method provides error-free data transmission?
Store-and-Forward
What are the disadvantage of serial transmission?
Speed... a serial connection can only send one piece of data at a time. Parallel connections have multiple data 'channels' sending data simultaneously 0- which increases the data rate considerably.
Serial refers to a style of data transmission in which the pulses that represent bits follow one another along a transmission line?
single
Serial refers to a style of data transmission in which the pulses that represent bits follow one another along a what transmission line?
Single
What is meant by serial and parallel transmission?
A serial port only allows a single bit of data through at a time. A parallel port allows multiple bits of data through at a time.
How is Bluetooth used?
Bluetooth provides an easier method of data transmission in short range distance.
