| Question | Answer |
| What is thermal compound used for? | Transfers heat between surfaces of two devices such as CPU to heatsink |
| When should you re-apply thermal compound? | Thermal compound should be re-applied each time you can see it. |
| What is a multiplier? | The speed ratio between the CPU and the front-side bus (FSB) |
| What does it mean to overclock a system? | Make it perform at a higher level than it was meant to |
| What is the danger in overclocking a system? | High temperatures that could lead to damaging computer devices as they could overheat |
| What is it mean to say that something actively cooled? | Using a fan to push the air through it |
| Is a heat sink an example of actively cooled or passively cooled? | Passively cooled |
| What is a yellow book standard? | CD ROM |
| What is a red book standard? | Audio CD |
| What is an orange book standard? | CD-R and CD-RW |
| How does CLV work in an optical drive? | The track moves at the same speed and the RPM varies |
| How does CAV work in an optical drive? | RPM remains constant while the data transfer rate (DTR) varies |
| What is the difference between PTP and OTP in DVD technology? | Opposite Track Path (OTP) accesses data from the outside to the centre of the disc while readout on Parallel Track Path (PTP) starts at the centre of the disc |
| As far as region codes, what region in Canada in? | 1 |
| If a CD ROM claims to be 24x what is the maximum data transfer rate? | 240 x 150 = 3600 kbps |
| How does blu-ray differ from DVD? | The colour of the laser is different and the storage size is greater on blu-ray |
| What do the jumpers on the back of a parallel ATA optical drive do? | Master and slave |
| Do jumpers on the SATA drive do? | speed limitations - you can make it act slower to match older standards |
| What is the capacity of a single-sided, single-layer DVD? | 4.7 GB |
| What is the capacity of a double-sided, double-layer DVD? | just short of 18 GB |
| What parallel expansion slot is still used by most motherboards? | PCI |
| What colour is the parallel expansion slot still used by most motherboards? | usually white |
| What is bus mastering? | A feature supported by many bus architectures that enables a device connected to the bus to initiate transactions |
| Can all ATP cards work in all ATP slots? | No as there will be some voltage issues |
| What is native resolution in a LCD monitor? | Single fixed resolution |
| Pixel is a contraction of what two words? | Picture and element |
| If you go to a larger resolution, do pixels increase in size? | No, they decrease in size. |
| What does contrast ratio measure in an LCD monitor? | It compares the brightest white to the darkest black |
| What does response time measure in an LCD monitor? | How quickly a monitor will react to changes on the screen |
| What are the two types of back lights that can be used in a screen | CCFL and LED |
| Out of CCFL or LED, which is more prone to failure? | CCFL |
| What are the advantages to LCD over CRT? | Lighter, smaller, more energy efficient and less radiation |
| How are CRTs better than LCDs? | Better viewing angle and colour calibration and contrast |
| What is a defective pixel? | A pixel that is stuck on a certain colour or perpetually on or off. |
| What is a shadow mask? | A perforated metal screen behind the phosphor screen, with holes which the electron beams passes through to strike the correct dots on the phosphor screen. |
| What is the alternative to a shadow mask in a CRT monitor? | Aperture grill |
| How do you measure the quality of a CRT monitor | Dot pitch |
| What are the three colours used in a phosphor triad? | Red, blue and green |
| Why is it dangerous to open a CRT? | High voltage concerns |
| What is the purpose of a deflection coil in a CRT? | It enables the electron beam to hit the correct spots on the shadow mask to the phosphorous screen |
| What adapters can be found on a video card? | HDMI, DVI, VGA, mini-display port |
| What is the difference between clone mode and span mode on desktop monitors? | Clone mode mirrors the image on more than one screen while scan mode lengthens the screen size to encompass more than one screen |
| What is the name of Nvidia's multi-video card solution? | SLI |
| What is the alternative to Nvidia's multi-video card solution? | CrossFire by AMD |
| What bus is typically used with CrossFire solutions? | PCI-Express |
| What are the advantages to using an SSD as opposed to a traditional hard drive? | Faster, smaller, no mechanical parts, lightweight |
| What are the disadvantages to using an SSD as opposed to a traditional hard drive? | Finite life and price concerns |
| What is garbage collection? | A form of automatic memory management on an SSD drive |
| What role does TRIM play in garbage collection? | TRIM tells the OS what pages are stale. |
| What is wear levelling and why is it important? | to ensure that the SSD wears evenly across the whole drive |
| What is write amplification? | Write amplification (WA) is an undesirable phenomenon associated with SSDs where the data is written over and over again. |
| What is the pink 3.5 mm jack? | Microphone |
| What is the green 3.5 mm jack? | Speaker out |
