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

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.
