System standby is a hardware/software solution where the hardware and software work together to manage the computer's power usage by shutting down some non-critical systems (Fans, drives, peripherals) and throttling back the critical ones (CPU, Network). Hibernation is a Software only solution that basically takes the current snapshot of the system (RAM memory) and writes it to the hard disk then informs the hardware that it should do a complete shutdown. When the hardware is turned back on, the hardware does a full POST (Power On/Self Test) process and then passes off to the software to do a full boot. Since the software wrote a copy of itself to the hard drive it skips it's full boot process and simply loads the system snapshot written to disk back into RAM and the applications that were running generally have no idea they were not running during that period of time the machine was "off".
Typically system standby can be set more aggressively (i.e. less than 30 minutes) because of a quicker wake up time - thus saving more energy. System standby keeps RAM powered rather than writing the system's current RAM image to the hard drive and thus responds quicker to wake up events. For comparison, typical hibernate settings are 60 - 120 minutes.
System Standby allows the computer to wake and respond to modem, peripheral and network interrupt requests while hibernation does not allow such events to trigger the machine to come up from a hibernation state. Hibernation does allow a Wake-On-LAN (WOL) network event to bring the system back up from the "off" state but this WOL signal requires special administrative tools network administrators typically use to centrally manage PCs.
Typically system standby requires keyboard or mouse activity for a wake up, while hibernate requires a push of the power button. As with monitor power management, a keyboard or mouse wake up the computer, therefore it is easier for users to get accustomed to system standby. With hibernate, users have to first tap the keyboard to see if only monitor power management is engaged, and then push the power button to wake from hibernate.
If data retention, in say the face of a power outage, is desired then hibernate can be set in addition to system standby. For example, a power outage knocks out two machines. One in standby and the other in hibernation. Any unsaved files on the standby machine may be lost while anything on the hibernating machine will be saved since the RAM has been written to disk.
The following power management configuration would constitute an "aggressive" policy for energy savings but minimize wake up time and provide minimal data retention protections.
Monitor: 5 minutes
System Standby: 15 minutes
Hibernate: 60 minutes
Continually placing a system in Hibernation means that the system stays loading without being refreshed from the disk. Although operating systems like Windows 2000 and XP have improved in their stability, it is still better to periodically reboot them to avoid crashes. Utilizing System Standby and shutting down overnight forces this periodic shutdown and makes for a better user experience.

nah it not bad. I do that all the time. I mean the computer most people leave on, but you can still shut it down if u are not going to use it for a while. The only thing bad is that you won be able to access it right away. you have to turn it on first. That the only flaw i see to it.

No, this is fine, as long as you follow the correct shut down procedure. My computers a couple of years old now and some days I shut it down a few times.

Depends. I leave my on all the time. Now if you have a room and it is constantly hot turn the computer off when you can. Buddy of mine had a hot room, old computer, and it broke down. But my room stays cool and i leave it on all the time. I have had it now 2 years, but getting ready to upgrade.

if you shut it off you won't get all the anti-virus updates or Microsoft security updates. that would certainly make your computer more susceptible to get a virus. my computers run 24/7 and i have no problems with attacks. when i do shut them off i make sure that when i turn them on i run updates before i go online. logging off is fine you may need to protect info in your account.
