Why is my television suddenly turning yellow?

Why is it necessary to follow shutdown procedures rather than turning off the computer like the television in other words what are its effects?

• Answer:

  Operating System has to deal with itself As you may know, a computer which is running has two side one has to consider: 1. A running computer is an electrical device in which billions of elementary operations take place per second. When a computer is switched on, an avalance of tiny electric signals travelling through tiny conductors, sets the computer in a state which responds in a certain way to external signals, such as keyboard input. It is extremely complicated and difficult for an average user to interact with the machine on that level directly. Therefor, there is special software writen which hides this complicated interaction interface from the user and offers a much more user-friendly interface to interact with. That is the... 2. Operating System: the software which intermediates between a human user and a computer machine. The operating system is able to communicate both with the computer's complicated interface and with the intuitive humans. Therefor, it is responsible for the translation of human messages to the computer and vice-versa. The operating System (Linux, MacOS, Windows, ...) is a quite complicated software itself. It has to keep a big amount of internal operation data. When a computer is being switched off, the operating system has to make sure none of its internal structure is ruined. That requires some extra time and computations to be run so that the internal state of the operating system is "cleanly" destroyed and the appropriate data stored to a persistent storage medium (hard disk, for example). If there was a computer with no operating system running on it (as there are some), one could just pull the plug and no harm would be caused.
