Q: What is difference between Cold Boot and Warm Boot?

We actually perform a Cold Boot every time we turn on the power switch of our computer. To “boot” the computer means to start it up and reset the memory and BIOS. Sometimes, the programme running hangs and we press the ctrl-alt-delete keys simultaneously. This is called Warm Boot. So, when a computer stops responding because of memory problems or the “blue screen of death” appears, we need to do a warm boot. The latest operating system Windows 7 responds with task manager when we press the ctrl-alt-delete keys simultaneously. We can choose the not responding programmes to close and continue. However, if the warm boot fails to restart the computer, we need to resort to a cold boot by shutting off the power switch, waiting few seconds and then turning it back on.
