What are some common error detection techniques in data transmission?
Common techniques include parity checks, checksums, and cyclic redundancy checks (CRC). Each has its own use cases.
Can you explain how a checksum works?
A checksum is a value calculated from a data set to verify its integrity. If the checksum matches on both ends, the data is likely intact.
What is the difference between even and odd parity?
Even parity adds a bit to make the total number of 1s even, while odd parity makes it odd. Both help detect single-bit errors.
Are there any limitations to these techniques?
Yes, while they can detect errors, they may not correct them. Some techniques can also miss certain types of errors.
