  1. 1What is ESD?Electrostatic Discharge
  2. 2What damage can ESD do?It can damage your MOS-based components
  3. 3What might one do to mitigate ESD?Wear an anti-static wrist strap
  4. 4What are the 2 types of screws used in desktop computers?M3 (fine thread) and 632 (course thread)
  5. 5Where would you use an M3 screw?On an optical drive and on 2.5 inch form factors
  6. 6What would use a 632 screw?Case, power supply, 3.5 drives, etc.
  7. 7What term are components such as motherboards known by to describe their shape and dimension?Form factor (example: ATX)
  8. 8Besides ATX, what are some other popular form factors?Micro-ATX, mini-ITX, BTX and (server only) NLX
  9. 9What “flash in the pan” form factor for motherboards has I/O ports on opposite side compared to the more popular ATXBTX
  10. 10What server form factor uses riser card at the very edge of the motherboard?NLX
  11. 11What is the difference between ATX and micro-ATX?Size
  12. 12Could you install an ATX motherboard into a system that held a micro-ATX board?No
  13. 13Could you install a micro-ATX motherboard into a system that held an ATX board?Yes
  14. 14What is the form factor typically used in small home-theatre cases?Mini-ITX
  15. 15What are some synonyms for the term motherboard?Main board (or mobo), system board or planar.
  16. 16What are the two common (or typical) sizes of hard drives?2.5 inch and 3.5 inch
  17. 17What are some common rotational speeds of a hard drive?5400 rpm, 7200 rpm and 10000 rpm
  18. 18What interfaces are typically used in hard disk drives and optical drives?SATA, Parallel ATA, SCSI and external solutions (usb, firewire, thunderbolt and eSATA)
  19. 19What is a sector?Subdivision of a track on a magnetic disk or an optical disc.
  20. 20What is a cluster?A group of sectors.
  21. 21What is a track?A circular path on the surface of a disk
  22. 22What is a head crash?The read/write head comes in contact with the disk.
  23. 23What damage can be done by a head crash?Loss of data and may make the hard drive useless.
  24. 24How is a serial ATA cable different from a parallel ATA cable?Parallel ATA is a ribbon while serial ATA is much thinner and serial ATA is point to point whereas parallel ATA is daisy-chained.
  25. 25What two filters are found in mechanical hard drives?Recirculating filter and barometric filter.
  26. 26In hard drives what does the voice coil motor move?The actuator arm
  27. 27What is S.M.A.R.T.?S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) is a technology that enables the user to determine a hard drive's reliability and state of its health.
  28. 28How would you describe RAID 0?Striping
  29. 29How would you describe RAID 1?Mirroring
  30. 30How would you describe RAID 3 and 4?Striping with dedicated parity

  33. 33What RAID level is least likely to be utilized?RAID 2
  34. 34What level of RAID does not provide fault tolerance?RAID 0
  35. 35What level of RAID does not use striping of any kind?RAID 1
  36. 36What level of RAID can withstand a failure of 2 drives and still recover?RAID 6
  37. 37What does fault tolerance mean?If something fails then the system will still work
  38. 38What is a software RAID?The RAID task
    runs on the CPU of your computer system
