Error Detection Techniques Quiz

What is the purpose of error detection techniques in data transmission?

• To ensure the accuracy and integrity of the transmitted data.

• To intentionally corrupt the transmitted data

• To ensure the data is lost during transmission

• To slow down the transmission process

What is the main function of a cyclic redundancy check (CRC) algorithm?

• To increase data transfer speed

• To compress data

• To encrypt data

• To detect errors in data transmission

How is a parity bit calculated in error detection?

• By adding the total count of 1s to the total count of 0s

• By multiplying all the data bits together

• By counting the number of 1s in a set of data bits and adding a 1 if the total count is even, or adding a 0 if the total count is odd.

• By randomly selecting a 1 or 0

What are the different methods for calculating checksum in error detection?

• SHA-256

• MD5

• Internet Checksum, CRC, Adler-32

• RSA

Which error detection technique is commonly used in computer networks?

• Compression

• Checksum

• Encryption

• Parity bit

What is the significance of error detection in ensuring data integrity?

• It slows down the data processing

• It helps in identifying and correcting errors in the data.

• It increases the likelihood of errors in the data

• It has no impact on data integrity

How does a cyclic redundancy check (CRC) algorithm detect errors in data?

• By generating a checksum and comparing it to the received checksum

• By encrypting the data and comparing it to the original data

• By compressing the data and checking for any loss of information

• By counting the number of bits in the data

What are the advantages of using parity checks for error detection?

• Only detects errors in the data transmission

• Causes more errors to occur

• Provides error detection for single-bit and some multiple-bit errors

• Slows down the error detection process

Discuss the importance of checksum calculation methods in error detection.

• Data encryption and decryption

• Network routing protocols

• Data integrity and error detection

• Hardware maintenance and troubleshooting
