when does the michelangelo virus take effect every year
Michelangelo (computer virus) On March 6, if the PC is an AT or a PS/2, the virus overwrites the first one hundred sectors of the hard disk with nulls. The virus assumes a geometry of 256 cylinders, 4 heads, 17 sectors per track. Although all the user's data would still be on the hard disk, it would be irretrievable for the average user.[citation needed]
Germ theory of disease The more formal experiments on the relationship between germ and disease were conducted by Louis Pasteur between the year 1860 and 1864. He discovered the pathology of the puerperal fever[23] and the pyogenic vibrio in the blood, and suggested using boric acid to kill these microorganisms before and after confinement.
