Which power option closes all files programs and the operating systems and turns off the power?
|
Graceful shutdown and hard shutdown are two opposing methods of turning off a computer. A graceful shutdown is when a computer is turned off by software function and the operating system (OS) is allowed to perform its tasks of safely shutting down processes and closing connections. A hard shutdown is when the computer is forcibly shut down by interruption of power. Show Graceful shutdowns are generally performed intentionally by users, as a part of their daily routines, at the end of a work day or when finished with home use of a computer. Hard shutdowns maybe unintentional due to power disconnects, electronic protection circuits or hardware failures. In the case of some safety issues like computer fires or security issues like malware or hacked computers, hard shutdowns may be as a safety precaution by users or IT departments. Generally, a graceful shutdown is preferable in the case of any OS that saves its state. When the standard shutdown procedures are not done with these OSs, the result can be data corruption of program and operating system files. The result of the corruption can be instability, incorrect functioning or failure to boot. Many modern OSs and other software are fault tolerant and generally handle the odd power interruption without issue. Both Bare metal and virtualized systems can be affected by hard shutdowns, so they should be avoided when unnecessary. Virtual machines (VM) may need to be restored from backups, while bare metal systems may even require a full reinstall.

Power cycling is the process of turning hardware off and then turning it on again. In the data center, technicians use power cycling to test the durability and reliability of network components. It is commonplace for servers to operate for months or even years without a reboot or disruption. These long periods of uninterrupted operation can place the entire system's resilience and reliability into doubt. Regular power cycling tests proactively monitor system performance and identify potential hardware failures arising from a hard restart. These tests can also reveal the amount of downtime that can occur after an unexpected hardware shutdown, and ensure proper system reconfiguration and accessibility after a restart. It's a best practice to make sure these tests comply with other disaster recovery and shutdown procedures. Power cycling is often done remotely using systems management tools that stop/close applications, close any open data files, and then finally shut down power. This orderly shutdown process reduces the chances of accidental data or file corruption. Once the power is off, the system is restarted remotely, using technologies such as Wake-on-LAN. Technicians often wait several seconds before restarting the system to ensure that any dynamic volatile memory has cleared completely. If a system has become unresponsive, or cannot be shut down remotely, technicians can manually cycle power by holding down the physical power switch for several seconds, waiting several more seconds for memory contents to clear, and then using the power switch to restart the system. This method, however, does risk some data loss if open applications or data files are not closed first. This was last updated in January 2017 Continue Reading About power cycling

Which option of power mode will you choose to turn off your computer completely?Turn your PC off completely
To shut down, select Start and then select Power > Shut down.
Which menu has the power options to shut down log off or restart a computer?Method 1: Click the Start button, and on the Start Menu, click the Power icon. On the Power menu, click to select the desired action (Sleep, Shutdown or Restart).
What is the function of log off?Logging out helps prevent other users from accessing the system without verifying their credentials. It also helps protect the current user's access or prevent unauthorized actions on the current login session and is thus an important part of security.
How do you power on a system and shut it down?Press Ctrl + Alt + Del and click the power button in the bottom-right corner of the screen. From the Windows desktop, press Alt + F4 to get the Shut down Windows screen and select Shut down. If you don't have a mouse, use the Tab and arrow keys to switch between fields.
