A. Black spots
B. Streaks
C. Faded prints
D. Garbled output
C. Faded prints

You may be able to ping the entire network using IP addresses, but most access is done by name, not IP address. If you can’t ping resources by name, DNS is not functional, meaning either the DNS server is down or the local machine is not configured with the correct IP address of the DNS server.
What is the light in the device that powers the LCD screen?
A. Backlight
B. Inverter
C. Charger
D. Reflector
A. Backlight
The backlight is the light in the device that powers the LCD screen. It can go bad over time and need to be replaced, and it can also be held captive by the inverter. The inverter takes the DC power the laptop is providing and boosts it up to AC to run the backlight. If the inverter goes bad, you can replace it on most models (it’s cheaper than the backlight).
