Data Transmission Quiz

What is one method used to detect errors in data transmission?

• Parity check

• Data compression

• Encryption

• Data mining

What can cause data to be transmitted incorrectly?

• Power surges

• High-speed internet

• Data encryption

• Cloud storage

What is the consequence of a single bit being incorrectly transmitted?

• Significant consequences

• No effect

• Faster transmission

• Improved security

Which of the following techniques is used to ensure data arrives in the same state as it was sent?

• Parity Checks

• Data Compression

• Encryption

• Data Sorting

What is the purpose of a parity check in data transmission?

• To detect transmission errors by counting the number of ON bits

• To compress data for faster transmission

• To encrypt data for security

• To sort data in alphabetical order

In the example provided, what is the parity bit added to the data "1001101" to ensure even parity?

• 0

• 1

• 2

• 3

What does an odd number of ON bits in received data indicate (in an Event Parity setup)?

• An error has occurred in transmission

• The data is compressed

• The data is encrypted

• The data is sorted

What is the purpose of adding an odd parity bit to data before sending it?

• To ensure the total number of ON bits is even

• To ensure the total number of ON bits is odd

• To increase the data size

• To decrease the data size

What does it indicate if the received data has an even number of ON bits?

• The data has been sent correctly

• An error has occurred in transmission

• The data size has increased

• The data size has decreased

Which type of error is not detected by parity bits?

• Single bit errors

• Transposition errors

• Odd number of bit errors

• Even number of bit errors
