1.	________ is the mechanism of sending data bits multiple times to ensure consistency.(a) Repetition(b) Duplication(c) Mirroring(d) RedundancyThe question was posed to me in a national level competition.My doubt is from Checksum, Complexity Classes & NP Complete Problems in section Checksum, Complexity Classes & NP Complete Problems of Data Structures & Algorithms II
Answer» Correct option is (a) REPETITION The best I can EXPLAIN: Repeating data BITS multiple times is done to ensure consistency. If the data bit to be sent is a 1, a n=3 repetition code will send 111. If the bits are not the same, an ERROR has occurred.
