In digital systems, the analog signals will change into a digital sequence. This sequence of bits is called Data stream. The objective of this paper represents that the change in position of a single bit also leads to a major error in the data output. In this paper, we present an overview of error control regarding error detection and error correction. It reveals that finds errors and uses error detection and correction techniques to get the exact or approximate output. Error control describes how the network handles and detects errors, especially in the data link layer. This article mainly discusses the type of error detection mechanisms that are used to detect the errors and how the errors can be corrected so the receiver can extract the real data.
