1. How many FireWire devices can a single FireWire port support?

12

25

32

54

63

127

A single FireWire port can support up to 63 FireWire devices. FireWire is a high-speed data transfer technology that allows multiple devices to be connected to a computer through a single port. The number 63 indicates the maximum number of devices that can be connected simultaneously without causing any performance issues or data transfer limitations.

2. Which type of memory transfers data twice as fast as SDRAM and increases performance by transferring data twice per cycle?

DDR-SDRAM

DRAM2

D-SDRAM

ROM

DDR-SDRAM stands for Double Data Rate Synchronous Dynamic Random Access Memory. It is a type of memory that transfers data twice as fast as SDRAM (Synchronous Dynamic Random Access Memory). DDR-SDRAM increases performance by transferring data twice per cycle, which means it can transfer data on both the rising and falling edges of the clock signal. This allows for higher data transfer rates and improved overall system performance.

3. What is the maximum data speed of high-speed USB 2.0?

1.5 Mbps

12 Mbps

380 Mbps

480 Mbps

480 Gbps

840 Gbps

The maximum data speed of high-speed USB 2.0 is 480 Mbps. This is the correct answer because USB 2.0 is capable of transferring data at a maximum rate of 480 megabits per second.

Explanation

The maximum data speed of high-speed USB 2.0 is 480 Mbps. This is the correct answer because USB 2.0 is capable of transferring data at a maximum rate of 480 megabits per second.

4. How many universal serial bus (USB) devices can be connected to a USB port?

256

127

64

128

A USB port can support up to 127 USB devices. This is because USB technology uses a 7-bit address field, allowing for a maximum of 127 unique addresses. Each USB device connected to the port is assigned a unique address, and the port can handle communication with all of these devices simultaneously. Therefore, the correct answer is 127.

5. Which type of video connector has a 24-pin or 29-pin female connector and provides compressed digital output to a monitor?

AAV

DVI

HDMI

RCA

VGA

DVI stands for Digital Visual Interface and is a video connector that has a 24-pin or 29-pin female connector. It provides compressed digital output to a monitor, making it a suitable choice for transmitting high-quality video signals. DVI cables are commonly used to connect computers to monitors or projectors, ensuring a clear and sharp display.
