Computer System Maintenance
Airlines, trucking companies, and other large organizations devote much more time, money, and effort to cleaning and preventative maintenance than they do to repairs. That's because cleaning and regular system maintenance repay their costs many times over by reducing the frequency and cost of repairs. It's almost always cheaper to prevent something from breaking than it is to fix it after it's broken. The same is true for PCs.
