------------------------------------------------------------------------------------------------------------------
By the end of the session today, you will be able to:
  • Differentiate between shut down and restart
  • Differentiate between Cold Booting and Warm booting
  • Understand the purpose of Log off and power on.
  • Understand the purpose of the shortcut keys in windows and their purpose.
  • Their implementation in real life situations
------------------------------------------------------------------------------------------------------------


  • To shut down (or power down, or power off) a system means that, when the process of shutting down is complete, the machine is powered down, and it will not come back up again without a someone taking further action, e.g., powering it back on again. If you expect your system will be needed for maintenance or remote access by someone else, shutting it down effectively prevents this.

  • To restart (or reboot) a system means that the computer goes through a complete shutdown process, then starts back up again. This is frequently required after software installations or during troubleshooting.

  • To log off a system means that the user who is currently logged on has their session end, but leaves the computer running for someone else to use. This is faster than a full restart and, generally, a better choice during the course of the business day when a system is shared between multiple users.

  • To power on a system means that you simply press the power button and let the system come up to a login prompt.
  • If you enter your username and password, you have gone a step further and have logged on.

What is Cold Booting

Cold booting is the process of starting up a computer that is switched off.  Usually, it is performed by pressing the power button on the computer. 
Cold booting performs the “Power on Self-Test” (POST). It is a series of system checks at the beginning of the boot sequence. 
In other words, it checks whether all the requirements are met, and the hardware is working correctly before starting the operating system.
When troubleshooting the computer, the user is asked to turn off the computer completely. 
Then cold booting is performed. It clears all temporary data from the system and eliminates the issues that can affect the functionality of the computer.

What is Warm Booting

Warm booting is the process of restarting a computer. 
It can be initialized using the operating system. 
In Windows, the user can perform warm booting by selecting the restart option from the start menu. In Mac, the user can perform warm booting by selecting restart from the Apple menu. 
  
                                            
Windows Shortcut Keys(contd.)
  • Alt + Spacebar: Open menu for active program.
  • Ctrl + Left or Right Arrow: Move cursor forward or back one word.
  • Ctrl + Up or Down Arrow: Move cursor forward or back one paragraph.
  • F1: Open Help menu for active application.
  • Windows Key + M: Minimize all windows.
  • Shift + Windows Key + M: Restore windows that were minimized with previous keystroke.
  • Windows + F1: Open Windows Help and Support.
  • Windows + Tab: Open Task view.
  • Ctrl+Alt+Del: Restart computer.
  • Left Alt + Left Shift + Print Screen: Switch High Contrast on and off
