Q. Explain Error Detection and Correction Codes?
Before we wind up data representation in reference of today's computers one should determine about code that helps in correction and recognition of errors. Computer is an electronic media hence there is a probability of errors at the time of data transmission. These kinds of errors can result from disturbances in transmission media or external environment. But what is an error in binary bit? An error bit alters from 0 to 1 or 1 to 0. One of simplest error detection codes is known as parity bit.
