Preventive Maintenance
You might have heard the old saying, “An ounce of prevention is worth a pound of cure.” In computers,
this expression is very true because a little preventive maintenance can prevent some major problems
down the road. However, no matter how much preventive maintenance you perform, problems will
eventually occur if you wait long enough. Therefore, you will need to know how to troubleshoot these
problems using a systematic approach.
