Clarification on inverters?
The exam cram practice exams says it converts AC to DC but other sources says it converts DC to AC. Is this an error in the exam cram practice test?
The exam cram says power inverter but when I googled it, a power inverter is an inverter, no difference. Help thanks

Computers use Direct current.
So in practice its AC to DC for a test question.
Is that site wrong? They said DC to AC
AC comes from a wall socket from the power company.
DC is from sources such as batteries.
Your laptop would have an AC converter that you plug in the wall and then changes to DC with a "converter" to charge the battery. The battery is also then DC to your computer because the things inside require the specific voltages. LCD requires an inverter because it needs AC.
By definition an "inverter" converts DC to AC.
Does exam cram really say that? You might be thinking of a converter instead of inverter.
I'm just confused, hope someone can help me. Thanks
Ignore the "You answered this question correctly" I pressed the button to show the answer
From your reply, the outlet is AC powered and the laptop requires DC to run, so an inverter does convert from AC to DC.
The laptop needs DC power to run? or is it AC Outlet > DC Battery > then back to AC? LOL sorry for all the mess
Professor Messer references inverters in the correct context: "So behind that laptop screen are something called inverters that will take that DC power that’s coming into the laptop and converts it now into AC power that is used to power those fluorescent lights."
Calling a laptop's power adapter an inverter is just wrong.
