Explanation:
When an error occurs in data bits, the SEC code is used to determine where the error took place. 5 check-bits are needed to generate SEC code for 16-bits data word. The check bits are:
C16=0, C8=0, C4=0,C2=0,C1=1
Therefore the SEC code is 010100000001101000101
Answer:
In studies about new medicines, researchers usually give one group of patients the medicine that is designed to treat an illness. They give another group of patients a placebo, which is taken the same way as the medicine but does not actually contain the ingredients of any medicine. Different medicines are tested in different experiments, but the placebos usually contain the same non-medical ingredients. If both groups of patients are healed, then researchers cannot be sure whether the medicine caused improvement, but if the group given the medicine is healed while the group given the placebo remains ill, researchers can conclude that the medicine causes the illness to go away.
In medical experiments, which group receives placebos?
the experimental group
the control group
both the experimental and control groups
neither the experimental nor control group
