67

A M.2 card has ________ pins

52

A Mini PCIe card has a ________ pin edge connector

Wi-Fi

A ________ card, also known as a _________ network adapter, allows us to connect to a WLAN (wireless local area network), which is essentially another name for a Wi-Fi network

docking station, port replicator

A laptop is placed or "docked" into a ________ ________. However, a ________ ________ is connected to the laptop simply to provide additional ports.

LCD

the type of display that uses a screen inverter

LCD (liquid crystal display)

this type of screen is usually lit by a CCFL (known as the backlight) and the backlight is driven by a high-voltage inverter circuit (which is prone to failure)

damaged inverter or worn-out backlight

two common LCD display failure reasons

worn-out backlight

The following could indicate that what is wearing out? • a dimmer screen than before • a reddish/pinkish hue to the screen • out loss of color on screen

LED and OLED

These monitor types do not incorporate an inverter or a lamp.

inverter

Be sure to turn off and unplug the laptop and remove the battery before removing an ________.

TFT (thin film transistor)

Most of today's LCD screen are _______, meaning they have multiple transistors for each pixel.

M.2, Mini PCIe

Typically ________ cards are attached with one screw and ________ cards are attached with two screens

screen inverter

a device that coverts direct current (DC) that comes from the motherboard into alternating current (AC) to be used by the display's backlight.

webcam

a laptop microphone is often part of the ________ module.

function, operating

a laptop webcam can be disabled sometimes with a ________ key or in the ________ system.

OLED (organic light-emitting diode)

a monitor that is cheaper in it's manufacturing cost. • they can be printed onto just about any substrate using simple printing processes—and they can be incredibly small (even one per pixel), all lighting individually. • uses an organic compound to emit light in response to an electric current

LED (light-emitting diode)

a monitor type that utilizes two-terminal electronic components known as diodes to display images. • They use less power than traditional LCDs and are therefore more efficient. • use light-emitting diodes, which release photons; this process is known as electroluminescence.

digitizer

a touchscreen is also known as a _________, which converts tapped or written impulses (analog) on the screen into instructions (digital) for the operating system to follow.
