Data Transmission Error Checking Recap Quiz

What is the purpose of error checking methods in data transmission?

• To compress data for faster transfer

• To detect errors in transmitted data

• To encrypt data for security

• To increase data transmission speed

What does even parity require?

• An even number of 1-bits

• A single 1-bit

• An odd number of 1-bits

• No bits at all

What happens if two bits are transposed during transmission?

• The data is always corrupted

• The system may incorrectly assume data is correct

• The transmission is stopped

• The data is automatically corrected

What is a drawback of using parity checks?

• They are too complex to implement

• They can only detect single-bit errors

• They can be fooled by certain types of errors

• They require a lot of bandwidth

What is a parity byte used for?

• To store the original data

• To indicate the end of a block of data

• To compress the data

• To encrypt the data

What is the main function of a checksum?

• To verify the integrity of data

• To speed up data transmission

• To encrypt data

• To format data

What does ARQ stand for in error checking methods?

• Automatic Repeat Request

• Advanced Recovery Query

• Automatic Redundancy Quality

• Advanced Request Queue

What is the role of protocols in data transmission?

• To increase data speed

• To define the rules for data exchange

• To compress data

• To encrypt data

What is the main advantage of using parity blocks?

• They are faster than other methods

• They are easier to implement than single parity checks

• They can identify and locate errors

• They require less bandwidth

What is the first step in parity checking?

• Receiving the data

• Calculating the parity bit

• Sending the data

• Transmitting the parity byte
