Single error correction double error detection (SEC DED) codes are often employed in systems with error correcting code (ECC) memory SEC DED codes can correct if there is a single bit in a memory word that is flipped, and can detect (but not correct) if two bits are flipped If the size of a memory word is 4 bytes, and the probability of a bit being flipped is 0 2, then answer the following questions a) What is the probability that all bits in a memory word are correctly set (without any SEC DED corrections) b) What is the probability that SEC DED can detect an error but not correct it c) What is the probability that there are exactly two bits incorrectly flipped in a memory word, if we already know that one bit is flipped incorrectly d) If the content of a memory is known to be correct, what is the probability that it was corrected by SEC DED

Question: Single error correction-double-error detection (SEC-DED) codes are often employed in systems with error- correcting code (ECC) memory. SEC-DED codes can correct if there is a

Single error correction-double-error detection (SEC-DED) codes are often employed in systems with error- correcting code (ECC) memory. SEC-DED codes can correct if there is a single bit in a memory word that is flipped, and can detect (but not correct) if two bits are flipped. If the size of a memory word is 4 bytes, and the probability of a bit being flipped is 0.2, then answer the following questions.

a) What is the probability that all bits in a memory word are correctly set (without any SEC-DED corrections)?
b) What is the probability that SEC-DED can detect an error but not correct it?
c) What is the probability that there are exactly two bits incorrectly flipped in a memory word, if we already know that one bit is flipped incorrectly?
d) If the content of a memory is known to be correct, what is the probability that it was corrected by SEC-DED?
