Sleep Or Shutdown Or Hibernate ? What Is The Difference ?

Sleep Mode....

In Sleep Mode....Running Operations Are Saved And Stored On RAM. PC Do Not Consume Much Power But Still Slight Consumption As RAM Stores All Data. Its Like Rest Mode. PC Starts Quickly In Sleep Mode As All Boot Operations Are Not Required. Its A Power Saving Mode. When You Want To Go Out For Short Time And U Don't Want To Close Your Programs, Sleep Mode Is Preferable.

But What If Power Failure Occurs....

Well, In That Case You Will Loose All Your Data Because Data Is Stored In RAM (Volatile Memory). In Sleep Mode PC Is In Pause Mode, Same Like DVD Player When You Pause A Movie.

Is It Good To Use Sleep Mode....

Yes, You Can Use Sleep Mode But In Sleep Mode Power Is Still Consumed Circuits Are Heated. So If Quick Booting Of System Is Not Required Use Shutdown Mode And Give Components A Rest.

Alternate To Sleep Mode....

Yes, Hibernate Mode. It Save Running Program In File Which Is Stored On Hard Disk. So Next Time System Will Refer File While Booting. This Mode Is Slow Compare To Sleep But Faster That Shutdown.

Shutdown Mode....

Shutdown Mode Will Save And Close All Programs Running On System. It Clears RAM Memory. Power Supply Completely Stops. So Next Time Boot Process Starts From ZERO.

Use Of Shutdown Mode Is Necessary As It Avoids The RAM Memory Management Issues, Which May Slow Down Performance Of PC
