Without a regular maintenance schedule however, you could find out (the hard way) that a neglected computer is an energy hog - one that works harder than it needs to and one that could be a financial burden to replace. Let's talk about maintaining hardware. So much emphasis is put on maintaining a computer's operating system that we sometimes forget how important it is to maintain a computer's hardware components. Conditions allow a program to perform an action based on the outcome of a previous command.3 Using this type of instruction, we could instruct a program to do one thing if the "x" variable in our latter example turned out to be 7 days, and then do different thing if the variable turned out to be 3 days.
