Data Transmission

Serial transmission sends data ____________, one bit after another, over a single communication channel.

__________ communication involves data transmission in one direction only, from one sender to one receiver, with no feedback or acknowledgment.

In ____________ communication, data can be transmitted in both directions, but not simultaneously.

Which error checking method involves adding an extra bit to each byte or character to ensure even parity or odd parity?

• ARQ

• Checksum

• Parity

• CRC

______________ is a method used to encode data to prevent unauthorized access or eavesdropping during transmission.

What does CRC stand for in error checking?

• Cyclic Redundancy Check

• Checksum Redundancy Code

• Control and Redundancy Check

• Coded Routing Check

Which of the following is an advantage of serial transmission over parallel transmission?

• Faster data transfer rates

• Simpler implementation

• Simultaneous transmission of data bits

• Higher resistance to noise interference

In duplex communication, data is transmitted:

• In one direction at a time

• Simultaneously in both directions

• Alternating between different channels

• Without error checking mechanisms

Which method use acknowledgements and time out?

• ARQ

• Parity

• CRC

• Checkdigit

____________ involves the process of combining data with error-detecting code to ensure data integrity during transmission.
