Concerning the PSU, what should you always do when traveling to another country with your computer Athena lives in an area where the power is often interrupted She bought a good surge suppressor, but that does not seem to help What does she need to prevent her system from shutting down unexpectedly Your assistant technician calls you and says he suspects a bad power supply in one of your client s systems He said the multimeter readings are 1265 volts and 415 volts What should he do One of your clients has an older Pentium 4 system with a single IDE hard drive and 512 MB of RAM He had been using this PC as his main workstation, but he s recently purchased a newer system and now wants to redeploy the older system as a le server on his network He has ordered a PCI SCSI controller board and three SCSI hard drives, so that he can con gure a RAID array, and an additional 2 GB of RAM He also ordered two Y adapters for the power supply connectors He asks for your advice about any additional hardware he should order What do you tell him Toby has built a system that requires 480 W to operate properly He purchases a 500-W PSU for the system Why is this a bad idea

158 9: Hard Drive Technologies
As the primary storage area for the operating system, applications,
and vital data, the hard drive takes on a level of importance to PC users that borders on reverence Considering the fact that the death of a drive can mean many hours or days of tediously rebuilding your OS install, reloading applications, and re-creating data, such strong feelings make sense And that reverence can turn quickly to agony if the user hasn t backed up his or her data in a while when the hard drive dies! In the rst lab exercise, you will compare two different hard drive technologies: solid-state drives and magnetic hard drives You will then conduct research on the developments of the rapidly changing Small Computer Systems Interface (SCSI), primarily used for large, fault-tolerant data storage
