What Happens When You Don't Shutdown Your Computers Properly?

By Anonymous

When a computer is running, the hard disk rotates its platter thousands times in a minute, the read/write head moves forwards and backwards all the time, your operating system opens many files for reading and writing.


When you turn off the computer using the shutdown option in your operating system, it closes all the files that it is using and ends its access to them and to your system’s registry. And, the hard disk, positions its actuator arm at one side of the disk.


These are some cases wherein most computers are not shut down properly:
  • When power outage occurs (intentional or not)
  • When computer does not respond for several minutes even after using ctrl + alt + del
  • When a user holds down the power button for several seconds (intentional or not)
  • And, when we are just too lazy to turn off the computer normally and wait for it to shut down on its own.

What happens then if your computer is not shut down properly?

Your computer may not be able to finish reading or writing some system files in your hard drive which results in corrupted files especially in your system’s registry. The read/write head may have been resting on the hard drive’s platter while it is turned off. When the computer is turned on, it will cause a scratch on the platter and damage some of the stored data in your system.

Having a corrupted registry files in your system may end up to a non-booting computer which will cost you repairs and hardware replacement. The worst part is that you may not be able to access all your files ever again. You will lose all your data!
While shutting down your computer by pulling its plug may save your precious seconds, shutting it down properly while save your company or your wallet’s health.

By Anonymous
The Library Usage Log Once you enter the one of the libraries of MSU-IIT, our library staff reminds you to register your ID Number at the Online Library Usage Log. Importance of the Library Usage Log Quantitative and qualitative data about library services, library use and library users are essential for revealing and confirming the outstanding value that libraries provide.   As the informative value of such statistics depends on their comprehensiveness and speed, the participation of all libraries in the country will be necessary.

By Anonymous
On May 15, 2017, the College of Education Library opens its door to library patrons with its new arrangement. The circulation desk is now strategically situated near the entrance right in front of the online user registration system, Library Usage Log. Before, the circulation desk was situated in the center of the library right after the reading area. The problem that this arrangement imposes is that students who come inside the library most of the time disregard the Library Usage Log. This results in inaccurate library statistics of library usage every day which will then reflect to the satellite library’s report on library users.   CED Library Reading Area before the renovation Also, students are not properly monitored in the old arrangement.
