Question

1) Answer the following question in relation to adding parity bits as a means to detect error in block based transmission. a) Given the following bit strings 01100, 000, 11001001, 1000011, 1, and 00010. Which of the following bit strings have even and parity and odd parity

Answer 1

Parity bits are used to detect errors in block-based transmission. The given bit strings have either even or odd parity depending on the number of 1s in the string.

Step-by-step explanation:

Parity bits are used in block-based transmission to detect errors. They are additional bits added to a block of data to ensure that the number of 1s in the block is either even or odd. By comparing the number of 1s in the block with the expected parity (even or odd), errors can be detected.

In the given bit strings:

1. 01100 has even parity because it has an even number of 1s.
2. 000 has even parity because it has an even number of 1s.
3. 11001001 has odd parity because it has an odd number of 1s.
4. 1000011 has odd parity because it has an odd number of 1s.
5. 1 has odd parity because it has an odd number of 1s.
6. 00010 has even parity because it has an even number of 1s.
