Which display standard has a res of 1920x1200 and a 16:10 aspect ratio?
WUXGA (Widescreen Ultra eXtended Graphics Array)
What term describes when you get image distortion because the LCD monitor is not compatible with the video card?
What is the measure of the ratio between the lightest color and the darkest colort the screen is capable of producing?
What can you use to clean a LCD screen?
Damp cloth or LCD cleaner
What pointing device is basically a mouse turned upside down?
What device is a pad of touch-sensitive material and includes two buttons for left- and right-clicking?
What pointing device was released with the IBM ThinkPad series and uses a small rubber tipped stick?
Touchpoint (finger mouse)
What type of laptop was designed to be used like a notebook?
What standard was organized to provide a way of expanding portable computers?
PCMCIA (Personal Computer Memory Card International Association) or PC Card
What are the three major PC Cards (and slots) used for today?
- Type I: memory cards
- Type II: modems, LAN adapters, sound cards, SCSI controllers, etc.
- Type III: hard disks
PCMCIA need which software in order to operate?
- Socket Services: BIOS-level interface
- Card Services: interface between apps and Socket Services
What is an ExpressBus used to expand?
USB (daisy chain up to 127 devices)
What communication port is used to wirelessly (line of site) transfer data at up to 4Mbps?
What standard is used to wirelessly (line of site) transfer data at up to 16Mbps?
IrDA (Infrared Data Association) standard
What is a collection of IEEE 802.11x standards?

Which WiFi standard is backwards compatable, provides speeds up to 54Mbps and operates on the 2.4GHz band?
Which WiFi standard is not backwards compatable, provides speeds up to 54Mbps and operates on the 5GHz band?
Which WiFi standard is expected to be backwards compatable and should provide speeds over 200Mbps?
Which wireless standard can reliably transfer small amountso data quickly over short distances (30ft) and uses little power?
What can certain desktops connect to that is an extension of the motherboard?
What reproduces the functions of ports on the back of a laptop, so that peripherals don't have to be unplugged every time a laptop is moved?
What allows you to plug full-size devices into ports and take your laptop with you?

What standard gives power management to the OS and allows laptop power management features to be used on desktops? The motherboard, CPU, and OS must support it.
Advanced Configuration and Power Interface (BIOS-ACPI)
What are the four power level states, global states? (G0, G1, G2, G3)
- G0 Working: all devices are running at full power or low power/off for certain devices
- G1 Sleeping: divided into four submodes
- G2 Soft off: Click Turn Off Computer or Shutdown.
- G3 Mechanical off: Complete power loss (unplugged)
What are the four submoes of G1 Sleeping? (S1, S2, S3, S4)
- S1: CPU stops executing, cache is flushed, pwer is still provided to CPU and memory, unused devices are powered down, power-hungry
- S2: Processor is powered down. (Not typically used)
- S3 Standby/Suspend: Maintain power only to RAM. Saves running aps info.
- S4 Hibernation: Info in RAM is written to HD. Takes longer to restore.
What are the four processor states? (C0, C1, C2, C3)
- C0: operational state
- C1 Halt: powered-down state, but processor can be returned to action nearly instantaneously
- C2 Stop-Clock: uses less power than C1. Processor is sill visible to aps but takes longer to wake
- C3 Sleep: cache is flushed, takes a few seconds for the processor to be available
What are the four device states? (D0, D1, D2, D3)
- D0 Fully On: full operating state
- D1 and D2: intermediate power states. Device specific
- D3 Off: complete power down, not responsive
What states are sublevels to processor and device states that are designated P0-Pn, where n can be 1-16? (Larger numbers indicate greater power savings as well as more latency to become fully operational.)
