Security and Maintainance

  Security is very important and most people don't really take it seriously.  Would you leave your car unlocked, with the keys in it, and it is park at a busy mall or shopping center. No, is mostly like your answer so why leave your computer or network open for everyone to tamper with.  Just think about what is on your computer for a minute.  The top answer is probably your credit card infomation.  It might be cached on your computer.

  Maintainance can keep your computer running longer with failure less likely and also detecting problems earlier rather than later and having them fixed prior to a system crash.  Harddrives can crash but, what can you do about it. Well it might be more than you really know.
