Answer 1

Heya
_________________________________________________________

Error control is the technique of detecting and correcting blocks of data during communication. In other words, it checks the reliability of characters both at the bit level and packet level. If proper error control is in place, transmitted and received data is ensured to be identical, as in many cases communication channels can be highly unreliable.

Hope this helps you.
