Error Detection Techniques

What is the purpose of parity check in error detection?

• To compress data during transmission.

• To encrypt data during transmission.

• To correct errors in data transmission.

• To detect errors in data transmission.

How does parity check detect errors in data transmission?

• By multiplying an extra bit to check the parity of the data unit.

• By subtracting an extra bit to check the parity of the data unit.

• By adding an extra bit to check the parity of the data unit.

• By dividing an extra bit to check the parity of the data unit.

What are the limitations of parity check?

• Inability to detect multiple bit errors and inability to correct errors.

• Inability to detect transmission errors and inability to correct errors.

• Inability to detect any errors and inability to correct errors.

• Inability to detect single bit errors and inability to correct errors.

Explain the concept of checksum in error detection.

• Checksum is a simple error detection method used to ensure data integrity.

• Checksum is a method used to encrypt data for secure transmission.

• Checksum is a method used to correct errors in data transmission.

• Checksum is a complex error detection method used to ensure data integrity.

What is the difference between parity check and checksum?

How does checksum ensure data integrity?

• Checksum ensures data integrity by encrypting the data.

• Checksum ensures data integrity by randomly rearranging the data.

• Checksum ensures data integrity by compressing the data.

• Checksum ensures data integrity by comparing calculated values at the sending and receiving ends.

What are the advantages of using checksum over parity check?

• Checksum is less reliable and can only detect single errors compared to parity check.

• Checksum and parity check have the same level of reliability.

• Parity check is more reliable and can detect multiple errors compared to checksum.

• Checksum is more reliable and can detect multiple errors compared to parity check.

What are the applications of error detection techniques in real-world scenarios?

• Data analysis, social media, video streaming, online gaming

• Weather forecasting, stock market prediction, medical diagnosis, traffic management

• Music production, graphic design, virtual reality, artificial intelligence

• Data transmission, storage systems, digital communication, computer memory, error correction
