DATA TRANSMISSION

Which of the following is a method of data transmission where data flows in one direction only?

• Simplex

• Duplex

• Half Duplex

• Packet Switching

Answer explanation

In simplex data transmission, data flows in one direction only, from sender to receiver.

Which of the following is a method of data transmission where data flows in both directions at the same time?

• Simplex

• Duplex

• Half Duplex

• Packet Switching

Answer explanation

In duplex data transmission, data flows in both directions at the same time, from sender to receiver and vice versa.

Which of the following is a method of data transmission where data flows in both directions, but only one direction at a time?

• Simplex

• Duplex

• Half Duplex

• Packet Switching

Answer explanation

In half duplex data transmission, data flows in both directions, but only one direction at a time.

Which type of transmission can cover longer distances but is slower than parallel transmission?

• Parallel transmission

• Half-duplex transmission

• Serial transmission

• Full-duplex transmission

Answer explanation

Serial transmission sends data one bit at a time and can cover longer distances, but it is slower than parallel transmission.

Which of the following is a method of data transmission where data is sent one bit at a time?

• Packet Switching

• Serial Data Transmission

• Parallel Data Transmission

• Simplex

Answer explanation

In serial data transmission, data is sent one bit at a time.

Which of the following is a method of data transmission where multiple bits of data are sent at the same time?

• Packet Switching

• Serial Data Transmission

• Parallel Data Transmission

• Duplex

Answer explanation

In parallel data transmission, multiple bits of data are sent at the same time.

Which of the following is a method of data transmission where data is sent through a single channel at a time?

• Simplex

• Duplex

• Half Duplex

• Parallel Data Transmission

Answer explanation

In simplex data transmission, data is sent through a single channel at a time.

Which of the following devices uses serial data transmission?

• Keyboard

• Printer

• Hard Drive

• Ethernet Cable

Answer explanation

A keyboard uses serial data transmission to send data one bit at a time.

Which of the following devices uses parallel data transmission?

• USB Drive

• DVD Drive

• Printer

• Ethernet Cable

Answer explanation

A printer uses parallel data transmission to send data in parallel on multiple wires.

Which type of transmission is faster than serial transmission and can be used for high-speed data transfer?

• Parallel transmission

• Full-duplex transmission

• Simplex transmission

• Half-duplex transmission

Answer explanation

Parallel transmission sends multiple bits at once and is faster than serial transmission, making it suitable for high-speed data transfer.
