For standby in Windows systems, sleep function, I believe we all know and also used, this is commonplace, but from Windows Vista system, Microsoft in standby, sleep on the basis of the system to add a sleep function, many students know, whether it is standby or sleep, In order for the computer to save its current operating state, in order to quickly restore to the current working state, to avoid the trouble of restarting the computer, but also can save electricity, although standby, sleep and sleep can achieve our goal, but they work between the three principle and function is different, the following is a detailed explanation of WIN8, The function and difference of standby, dormancy and sleep in Win10 system.
When the system enters Standby mode, the current data and running state of the computer are still stored in memory, and in addition to memory other hardware (such as CPU, hard disk) are in a state of power outages, because the characteristics of memory is fast and easy to lose data, so enter the standby state, in the case of continuous power, Can quickly restore to standby before the state of operation, but if the power segment, then the computer again into the system is equivalent to reboot, standby when the running state will be lost.
Small knowledge: The data in memory is easy to lose, said is stored in the memory of the data in the power will be cleared after the blackout, this is also when our computer card, restart will be a lot of good reasons, because the memory of the data again clear zero!
After the system enters hibernation mode, the computer's current state of operation and data saved to the hard disk, and then the entire computer's hard key (CPU, memory, hard disk, etc.) are in a state of power outages, this mode is completely without electricity, when we need to recover, the system will read from the hard disk data content into memory, Because the speed of the hard drive is far from the memory, it is more time-consuming to wake up hibernation than to wake up standby, but hibernation is the whole hardware in power, so the next time you can revert to a computer running before hibernation even if the power is disconnected.
After the system enters the sleep mode, the running state and data of the computer's current memory are stored on the hard disk, and the running data in the memory is still present, which is equivalent to opening standby and hibernation at the same time;
If there are no power disconnect problems, then when the Wake Sleep state, first read data from memory, read fast to restore the computer's running state, if there is a power disconnect and other exceptions, then in the wake of sleep, the hard disk to recover data, the speed is relatively slow.
From this, the system into the sleep mode, in any case, will not lose data, in the case of disconnection power, and so on, can be quickly restored to the computer before the operation of sleep, so compared to standby and hibernation, sleep mode is not more than a raise it?
