Explain the process of detecting transmission errors and correcting them. 

In the realm of Data Communication and Computer Networks, ensuring the accuracy and integrity of transmitted data is of paramount importance. During transmission, data can become corrupted due to various noise sources, interference, or other transmission impairments. Therefore, mechanisms for error detection and error correction are essential to maintain reliable communication. This answer explores the processes involved in detecting and correcting transmission errors, including their techniques, principles, and practical implementations.

1. Introduction to Transmission Errors

When data is transmitted over a communication medium—be it wired or wireless—it is susceptible to errors. These errors may flip one or more bits in the data stream, causing the received data to differ from the original. Transmission errors can be broadly classified into:

• Single-bit errors: Only one bit of a data unit is changed.

• Burst errors: Two or more bits in the data unit have changed, which may occur in a sequence or scattered.

Error control mechanisms aim to detect such errors and take steps to correct them, ensuring accurate data delivery between sender and receiver.

2. Error Detection Techniques

Error detection is the process of identifying whether an error has occurred during transmission. However, detection does not imply correction; it only signals that an error has occurred. Common error detection techniques include:
