File compression involves encoding data using fewer bits than the original file. There are currently two different types of compression, they are lossless and lossy. Lossless compression uses a method which entails identifying and removing redundant bits, while maintaining the full integrity of the original file. Lossy compression on the other hand reduces the size of a file by identifying data that it deems unnecessary.
A computer or system crash is basically when an application or hardware component on a computer ceases to function properly.

A rather common problem that many people tend to have is when their mouse suddenly freezes or stops moving. The typical scenario goes something like this, your surfing the web, chatting to a friend or playing a computer game when the mouse pointer suddenly freezes. Your immediate reaction is to move the mouse around frantically in hopes of the mouse pointer springing back to life, but when that fails, you resort to switching your system off from the power button.
