Error control methods basics

par Sevinch

What is a parity bit used for in data transmission?

A bit added to data to indicate even or odd number of 1s

A bit that carries the payload only

A bit used to encrypt data

What does Hamming code primarily do?

Detects and corrects single-bit errors and detects two-bit errors

Encrypts data for secure transmission

Detects only parity errors

CRC stands for what?

Cyclic Redundancy Cipher

Coded Repetition Circuit

Cyclic Redundancy Check

ARQ is an error control approach that uses what mechanism?

Automatic encryption routing

Automatic repeat requests with acknowledgments

Adaptive random queuing

Where are Reed-Solomon codes commonly used?

Single-letter parity checks

CDs, DVDs, DVDs, and QR codes to correct burst errors

Phone numbers

How does a checksum differ from a CRC in robustness?

CRC encrypts data to prevent errors

CRC is generally more robust against errors

Checksum detects more errors

What is forward error correction (FEC)?

Adds redundant data to allow error correction without retransmission

Uses parity bits without redundancy

Relies on automatic retransmission only

What kind of errors can Reed-Solomon codes correct well?

Errors in encrypted streams

Random single-bit errors only

Burst errors in blocks

What is a parity bit most commonly used for?

Replacing lost bits in a stream

Detecting odd/even parity of 1s in a block

Encrypting data

Which technique is best for correcting burst errors in data blocks?

Plain XOR redundancy

Simple parity checking

Reed-Solomon error correction
