A. IRQ
B. DMA
D. I/O AddressExplanation
IRQ, DMA, and I/O Address are commonly used system resources for communication between the CPU or memory and other components in a computer.
IRQ (Interrupt Request) is used to signal the CPU that a device needs attention or that an event has occurred. It allows devices to interrupt the CPU and request immediate attention.
DMA (Direct Memory Access) is a feature that allows certain devices to transfer data directly to or from the computer's memory without involving the CPU. It helps in improving the efficiency of data transfer.
I/O Address (Input/Output Address) is a specific address range used by devices to communicate with the CPU. It allows devices to send and receive data to and from the CPU.
These three resources play a crucial role in facilitating communication and data transfer between various components of a computer system.Rate this question:

A tehnician creates a simple circuit that has a 9V light bulb attached to a 9V battery. The power output of the light bulb is 100W. Which equation should be used to calculate how much current in amps is required to archive the full 100W output from the 9V bulb ?
- A.
I=P/V = 100W/9V= 11.11A
- B.
I=P*V=100W*9V=900A
- C.
I=(P/2)*V=50W*9V=450A
- D.
I=P*2*V=100W*(9v+9v)=8100A
Correct Answer
A. I=P/V = 100W/9V= 11.11AExplanation
The equation I=P/V is used to calculate the current in amps required to achieve the full 100W output from the 9V bulb. By dividing the power (100W) by the voltage (9V), we get the current in amps (11.11A).Rate this question:

How many FireWire devices can be supported by a single FireWire port?
- A.
12
- B.
25
- C.
32
- D.
54
- E.
63
- F.
127
Correct Answer
E. 63Explanation
A single FireWire port can support up to 63 FireWire devices. This is because FireWire uses a daisy-chain topology, where devices are connected in a series. Each device in the chain can pass along the signal to the next device, allowing multiple devices to be connected to a single port. However, there is a limit to the number of devices that can be connected in a single chain, and in the case of FireWire, that limit is 63.Rate this question:

Which memory module has a front side bus speed of 200MHz?
- A.
DDR-333
- B.
DDR-400
- C.
DDR-667
- D.
DDR3-667
- E.
PC100 SDRAM
