Media access protocols use error correction technique to detect and correct the errors

• True

• False

Parity check is an error detection technique that tests the integrity of digital data transmitted in noisy media

• True

• False

There are two types of parity check which are even and odd parity check

• True

• False

"Even parity" systems make the parity bit 1 when an odd number of 1 bits are in the byte, while"odd parity" makes it 1 for an even number of 1s

• False

• True

Parity checking cannot detect two bits in error in the same byte, because the parity would still be correct for that binary sequence

• True

• False

M is the number of quantization levels or the number of symbols

• True

• False

If data is binary M=2

• True

• False
