54
63
127

2. Refer to the exhibit. Based on the advertisement that is shown, what is the native resolution of this computer system?
8x
3 GB
2.0 GHz
1919 MB
1280 x 800
13.35 x 9.57

3.Which three system resources are commonly used for communication between the CPU or memory and other components in the computer? (Choose three.)
IRQ
DMA
UDP
I/O address
USB
PnP

4. A technician creates a simple circuit that has a 9 V light bulb attached to a 9 V battery. The power output of the light bulb is 100 W. Which equation should be used to calculate how much current in amps is required to achieve the full 100 W output from the 9 V bulb?
I = P/V = 100W/9V = 11.11A
I = P*V = 100W*9V = 900A
I = (P/2)*V = 50W*9V = 450A
I = P*2*V = 100W*(9V + 9V) = 8100A
