Parity and Command Line Quiz

What is a parity bit?

• A 2-bit number added to a data byte

• A single bit that helps detect errors in data transmission

• A type of checksum used in files

• A command line instruction

What is a parity byte?

• A byte that indicates the total number of bits

• An 8-bit byte used for error checking in data transmission

• A byte that represents a file size

• A special command in a programming language

What is two-dimensional parity check?

• A method of organizing files in directories

• A technique that adds parity bits to both rows and columns of data

• A way to format text in documents

• A command used in computer networks

In a two-dimensional parity check, how is the parity for the last row calculated?

• By summing all bits in the last column

• By counting the number of 1s in the row

• By averaging the bits in the row

• By multiplying the bits together

What does it mean if the parity check fails in a two-dimensional parity system?

• The data is transmitted correctly

• There is an error in the data

• The parity bits are not needed

• The data is compressed

Given the transmitted data byte 11010101 and the 8-bit parity byte 11010110, is there an error if using even parity?

• Yes

• No

• Cannot determine

• The parity byte is incorrect

If the transmitted data byte is 10111000 with an 8-bit even parity byte of 10111100, what is the status of the transmission?

• Error detected

• No error detected

• Parity byte is incorrect

• Data is corrupted

You receive the data byte 11100101 with an 8-bit odd parity byte of 00011101. What does this indicate?

• No error detected

• Error detected

• Parity byte is incorrect

• Data is corrupted

If the data 11001100 is transmitted and the calculated even parity byte is 11001100 , what does this indicate?

• Error detected

• No error detected

• Parity byte is incorrect

• Data is corrupted

Given the byte 10101011, what would the odd parity byte be?

• 01000001

• 01010100

• 01010010

• 11111111
