what is this HIBERNATION means ?? what it does ??

HEBERNATION is the one of the state of computer in which all the data of RAM is stored on the Hard Disk and compter is shut down but it preserve your computer's last state and when u start computer next time then it starts at the state when you hibernate your computer...

HIBERNATION in relation with computers is a state of computer where the computer is at rest. This mode uses the least amount of enegry. The best thing is that at which state u leave that will like that.

maybe like this will clear a little bit, Hibernation is a state of inactivity and metabolic depression in animals, characterized by lower body temperature, slower breathing, and lower metabolic rate. Hibernation conserves energy, especially during winter. Hibernation may last several days or weeks depending on species, ambient temperature, and time of year. The typical winter season for a hibernator is characterized by periods of hibernation interrupted by sporadic euthermic arousals wherein body temperature is restored to typical values. Hibernation allows animals to conserve energy during the winter when food is short. During hibernation, animals drastically lower their metabolism so as to tap energy reserves stored as body fat at a slower rate. Animals that hibernate include bats, ground squirrels and other rodents, mouse lemurs, the European Hedgehog and other insectivores, monotremes and marsupials. Even some rattlesnakes, such as the Western Diamondback, are known to hibernate in caves every winter. Historically, Pliny the Elder believed that swallows hibernated, and ornithologist Gilbert White pointed to anecdotal evidence in The Natural History of Selborne that indicated as much. However, birds typically do not hibernate, instead utilizing torpor. An exceptional bird known as the Poorwill does hibernate[1]. Many experts believe that the processes of daily torpor and hibernation form a continuum. One animal that some famously consider a hibernator is the bear. However, during a bear's winter sleep state, the degree of metabolic depression is much less than what is observed in smaller mammals. Many prefer to use the term "denning" in place of hibernating. The bear's body temperature remains relatively stable (depressed from 37° C to approximately 31° C) and it can be easily aroused. In contrast, hibernating ground squirrels may have core body temperatures as low as -2° C. Some reptile species are said to brumate, or undergo brumation, but the connection to this phenomenon with hibernation is not clear. Before entering hibernation most species eat a large amount of food and store energy in fat deposits in order to survive the winter. Some species of mammals hibernate while gestating young, which are born shortly after the mother stops hibernating.

In hibernation mode your computer will save all your work and shutdown your computer.Its mainly used in laptop,when the battery gets low.

Hibernation has 2 meanings 1) It is a dormant state that living beings enter in winter to save energy. 2) It is a state that a windows PC can enter during which the contents of the computer's main memory is copied to a disk file so that the power can be turned off. THe main advantage is that shutdown and restarting is much faster. The disadvantage is that some applications break when this is done to them.
