Data Transmisssion

the transmission of data from one place to another.

• false

• true

walkie talkie is example of

• simplex

• half duplex

• full-duplex

• none of the above

a mobile cell is example of.

• Simplex.

• Half duplex.

• Full-duplex.

• None of the above

smallest unit of data in computer.

• Bit.

• Byte.

• Mega Byte.

• Kilo Byte.

The rate of transferring data is measured.

• Kilo Byte per Second

• Mega Byte per Second

• Bit rate.

• kilo meter per second

Uses a single wire to transfer bits of data

• serial transmission

• parallel transmission

• simplex transmission

Uses multiple wires to transfer data.

• Serial transmission

• Parallel transmission

• Simplex transmission

• Half-duplex transmission

Interference in the signals when sending data.

• Interference.

• Half-duplex transmission.

• Serial and Parallel data transmission.

Uses 1 bit at a time (safer/cheaper transmission and data will get sent at a long time without any mix-up).

• Serial transmission

• Parallel transmission

can send multiple bits (faster than serial. However, if one wire breaks, the data will get mixed up)

• Parallel transmission

• Serial transmission
