| Question | Answer |
| What is ESD? | Electrostatic Discharge |
| What damage can ESD do? | It can damage your MOS-based components |
| What might one do to mitigate ESD? | Wear an anti-static wrist strap |
| What are the 2 types of screws used in desktop computers? | M3 (fine thread) and 632 (course thread) |
| Where would you use an M3 screw? | On an optical drive and on 2.5 inch form factors |
| What would use a 632 screw? | Case, power supply, 3.5 drives, etc. |
| What term are components such as motherboards known by to describe their shape and dimension? | Form factor (example: ATX) |
| Besides ATX, what are some other popular form factors? | Micro-ATX, mini-ITX, BTX and (server only) NLX |
| What “flash in the pan” form factor for motherboards has I/O ports on opposite side compared to the more popular ATX | BTX |
| What server form factor uses riser card at the very edge of the motherboard? | NLX |
| What is the difference between ATX and micro-ATX? | Size |
| Could you install an ATX motherboard into a system that held a micro-ATX board? | No |
| Could you install a micro-ATX motherboard into a system that held an ATX board? | Yes |
| What is the form factor typically used in small home-theatre cases? | Mini-ITX |
| What are some synonyms for the term motherboard? | Main board (or mobo), system board or planar. |
| What are the two common (or typical) sizes of hard drives? | 2.5 inch and 3.5 inch |
| What are some common rotational speeds of a hard drive? | 5400 rpm, 7200 rpm and 10000 rpm |
| What interfaces are typically used in hard disk drives and optical drives? | SATA, Parallel ATA, SCSI and external solutions (usb, firewire, thunderbolt and eSATA) |
| What is a sector? | Subdivision of a track on a magnetic disk or an optical disc. |
| What is a cluster? | A group of sectors. |
| What is a track? | A circular path on the surface of a disk |
| What is a head crash? | The read/write head comes in contact with the disk. |
| What damage can be done by a head crash? | Loss of data and may make the hard drive useless. |
| How 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. |
| What two filters are found in mechanical hard drives? | Recirculating filter and barometric filter. |
| In hard drives what does the voice coil motor move? | The actuator arm |
| What 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. |
| How would you describe RAID 0? | Striping |
| How would you describe RAID 1? | Mirroring |
| How would you describe RAID 3 and 4? | Striping with dedicated parity |
| How would you describe RAID 5? | Striping with rotating parity |
| How is parity calculated? | Binary XOR calculation |
| What RAID level is least likely to be utilized? | RAID 2 |
| What level of RAID does not provide fault tolerance? | RAID 0 |
| What level of RAID does not use striping of any kind? | RAID 1 |
| What level of RAID can withstand a failure of 2 drives and still recover? | RAID 6 |
| What does fault tolerance mean? | If something fails then the system will still work |
| What is a software RAID? | The RAID task runs on the CPU of your computer system |
| What is a hardware RAID? | A hardware RAID solution has its own processor and memory to run the RAID application |
| What is the minimum amount of drives needed to implement RAID 5? | 3 drives |
| What is the minimum amount of drives needed to implement RAID 0? | 2 drives |
| What is the minimum amount of drives needed to implement RAID 6? | 4 drives |
| What is a hot spare in a RAID array? | Hot spare disks are powered & connected disk drives that are kept on active standby for use when a disk drive fails. |
| What has replaced PC cards in laptops? | ExpressCards |
| What does it mean to hot-plug or hot-swap a component? | The ability to replace or install a device without shutting down the attached computer |
| What is an example of a hot swappable component? | USB drive |
| How many pins are in DDR1? | 200 pins |
| How many pins are in DDR2? | 200 pins |
| How many pins are in DDR3? | 204 pins |
| What is the most popular battery type in today's laptops? | Lithium-ion |
| What is Speed Step? | An Intel innovation that allows the processor to run at a fraction of its speed to save power |
| Why is it impossible to upgrade the video card in most laptops? | The video card is built in to the motherboard |
| What is considered the most expensive part of a laptop to replace? | screen |
| What makes a Netbook different from a Notebook? | Netbook is usually smaller, has a starter version of the OS, is usually proprietary and has a light weight processor |
