1.	When 2 or more bits in a data unit has been changed during the transmission, the error is called ____________(a) random error(b) burst error(c) inverted error(d) double errorI had been asked this question by my school principal while I was bunking the class.This key question is from Data Link Layer topic in section OSI Model of Computer Network
Answer» Right answer is (b) burst error Explanation: When a SINGLE BIT error occurs in a data, it is CALLED single bit error. When more than a single bit of data is corrupted or has error, it is called burst error. If a single bit error occurs, the bit can be simply repaired by inverting it, but in CASE of a burst error, the sender has to send the frame again.
