Chapter 9 Flashcards
Is an extremely small laptop computer that is lighter in weight and more scaled down in features than a standard laptop. pg 397
Netbook
Primary differences between laptops and desktops. pg 397
portability cost performance expandability quality of construction
To save space components of the video circuitry and possibly other circuits as well are placed on a thin circuit board that connects directly to the motherboard. This circuit board is often known as a riser card or a what. pg 400
Daughterboard
To help combat this heat problem laptop processors are engineered with the following features: pg 400
Streamlined connection to the motherboard
Lower voltage and clock speed
Active sleep and slowdown modes
One of the earliest laptop-specific chipsets that gained a ton of popularity was Pentium M chip made by what company? p 401
Intel
The Pentium M consists of three separate components: p 401
The mobile Intel express chipset
The Intel/PRO wireless network connection
The Intel centrino
Some portable computer use stripped-down version of desktop processor such as what. p 401
Intel Pentium or Core series processor
There are two types of laptop memory packages what are they? p 402
SODIMM
MicroDIMM
Is an extremely small RAM form factor. In fact it is over 50 percent smaller than SODIMM. p 403
MicroDIMM
What are some of the special function keys of the laptop. p 405
number pad home insert PgUp PgDn
The function key combinations can control many laptop functions but the most common ones are? p 405
video
audio
networking
Video adjustments come in two varieties: p 406
changing the video output and dimming or brightening the screen
Essentially the same as a mouse turned upside down. p 409
trackball
actually the trade name of a product. p 409
touchpad
Device that uses a small rubber-tipped stick. p 410
point stick
Instead of a keyboard and mouse, these computer screens have a film over them that is sensitive to touch. p 410
touchscreen
PCMCIA stands for? p 411
Personal Computer Memory Card International Association
Adaptation of the peripheral component interconnect (PCI) standard used in desktop computers. p413
Mini PCI
Functionally identical to the PCI version 2.2 meaning it’s a 32-bit, 33MHz bus with a 3.3V-powered connection. p413
Mini PCI
Physically similar to ExpressCard devices without the external cover measuring a few millimeters less in length and width as a result. 52-pin edge connector, 1.5V and 3.3V power option. p 414
Mini PCIe
Designed to stay behind when the laptop is removed it can contain things like a full -sized drive bay and expansion bus slot. p 415
Docking station
Portable computer can use either two kind of power sources: p 416
batteries or adapter power from an AC or DC source
There are four types of batteries chemistries. p 416
Nickel cadmium (NiCd)
lithium-ion (Li-ion)
nickel-metal hydride (NiMH)
lithium-polymer (Li-poly)
The typical laptop display uses what kind of lamp as its backlight. p420
(CCFL) cold cathode fluorescent lamp
Small fluorescent lamp placed behind above or to the side of an LCD display. p 420
Backlight
Circuit board installed behind the LCD panel that takes DC current and inverts it to AC for the backlight. p 421
Inverter
What are the five steps of replacing the CMOS battery? p 435
Turn of the computer
Disconnect the computer and any peripherals from their power sources and remove any installed batteries
Remove the hard drive
Remove the keyboard
Disconnect the CMOS battery from the motherboard
(DVI) stands for? p 419
digital video interface
Most notebook computers can also use AC power with a special adapter called? p 418
AC adapter
What are the four common pointing points? p408
Trackball
Touchpad
Point stick
Touchscreen
There are three major types of PC cards. Each has different uses and physical characteristics each one measures 54 mm in width and 85.6 mm in length. p412
Type 1 are 3.3 mm thick used for memory
Type 2 are 5 mm thick used for modems and LAN adapters
Type 3 are 10.5 mm thick PC card hard disk. these slot are all but extinct
