    What type of wireless transmission requires a line-of-sight clearance?

    Correct Answer
    Infrared
    Explanation
    Infrared wireless transmission requires a line-of-sight clearance because it uses light waves to transmit data. These light waves are not able to penetrate solid objects, so there needs to be a direct line-of-sight between the transmitter and receiver for the transmission to be successful. This is why devices using infrared technology, such as remote controls, need to be pointed directly at the receiver for proper functioning.

    What command do you use to find out what version of DirectX your video card is using?

    Correct Answer
    dxdiag
    Explanation
    The command "dxdiag" is used to find out the version of DirectX that your video card is using. DirectX is a collection of application programming interfaces (APIs) developed by Microsoft to handle multimedia tasks, such as rendering graphics and playing audio. By running the "dxdiag" command, you can access the DirectX Diagnostic Tool, which provides detailed information about your system's DirectX version, display drivers, and other related components.

    Which is better for your eyes a monitor that supports 75hz refresh rate or one that supports 60hz refresh rate?

    • 75 Hz

    • 60 Hz

    Correct Answer
    A. 75 Hz
    Explanation
    A monitor that supports a higher refresh rate, such as 75 Hz, is better for your eyes compared to one that supports a lower refresh rate, such as 60 Hz. A higher refresh rate means that the monitor can display more frames per second, resulting in smoother and more fluid motion on the screen. This can reduce eye strain and fatigue, especially during prolonged use. Additionally, a higher refresh rate can also improve the overall visual experience, making images and videos appear more lifelike and realistic.

    Which USB Port is square and which USB port is flat and wide?

    • Type-B is square. Type-A is wide & flat.

    • Type-B is flat. Type-A is wide & flat.

    • Type-B is flat & wide. Type-A is wide.

    Correct Answer
    A. Type-B is square. Type-A is wide & flat.
    Explanation
    The correct answer is Type-B is square. Type-A is wide & flat. This is because Type-B USB ports have a square shape, while Type-A USB ports are wide and flat.

    Which type of port gives the best output a composite out port or an S-Video port?

    • Composite

    • S-Video

    Correct Answer
    A. S-Video
    Explanation
    The S-Video port gives the best output compared to a composite out port. S-Video separates the video signal into two components (luminance and chrominance) resulting in a higher quality picture with better color accuracy and sharper details. On the other hand, composite out port combines the video signal into a single channel, leading to a lower quality output with reduced color accuracy and less sharpness. Therefore, S-Video is preferred for achieving the best output quality.

    Which is faster, an eSATA port or a FireWire 800 port?

    • ESATA

    • FireWire 800

    Correct Answer
    A. ESATA
    Explanation
    eSATA is faster than a FireWire 800 port. eSATA stands for external Serial Advanced Technology Attachment and is designed specifically for connecting external storage devices. It offers faster data transfer speeds compared to FireWire 800, which is a high-speed interface used for connecting devices such as external hard drives and audio interfaces. Therefore, when it comes to speed, eSATA is the faster option between the two.

    For an LCD monitor what is the best resolution to use?

    • Inherent Resolution

    • 800x600

    • Native Resolution

    Correct Answer
    A. Native Resolution
    Explanation
    The best resolution to use for an LCD monitor is the native resolution. The native resolution refers to the resolution at which the monitor's display is designed to operate optimally. Using the native resolution ensures that the image displayed on the screen is sharp, clear, and properly scaled. It also prevents any distortion or blurriness that may occur when using a different resolution. Therefore, it is recommended to set the monitor's resolution to its native resolution for the best visual experience.

    Does Windows XP without any service packs applied support Hi-Speed USB?

    • Yes

    • No

    Correct Answer
    A. No
    Explanation
    Windows XP without any service packs applied does not support Hi-Speed USB. Hi-Speed USB, also known as USB 2.0, was introduced in 2000, after the release of Windows XP. The original version of Windows XP only supported USB 1.1, which had a lower data transfer rate. Support for USB 2.0 was added in Service Pack 1 for Windows XP. Therefore, without any service packs applied, Windows XP does not have native support for Hi-Speed USB.

    How many pins does the most common type of serial port have?

    Correct Answer
    9 pins
    Explanation
    The most common type of serial port, known as the RS-232 serial port, typically has 9 pins. These pins are used for various purposes such as transmitting and receiving data, grounding, and controlling flow of data. This configuration of 9 pins is widely adopted and compatible with a wide range of devices, making it the most common type of serial port.

    Which parallel port standard uses a DMA channel?

    • Extra Compatability Port

    • Extended Capabilities Port

    • LPT1 port

    Correct Answer
    A. Extended Capabilities Port
    Explanation
    The Extended Capabilities Port (ECP) is a parallel port standard that uses a DMA (Direct Memory Access) channel. DMA allows devices to transfer data directly to and from memory without involving the CPU, resulting in faster and more efficient data transfers. The ECP parallel port standard was introduced to provide enhanced capabilities and improved performance compared to the older parallel port standards. Therefore, the correct answer is the Extended Capabilities Port.

    Name three types of ports a keyboard might use?

    • 5-pin round DIN connector

    • 6-pin PS/2 connector

    • USB Port

    • Parallel Port

    • S/PDIF

    Correct Answer(s)
    A. 5-pin round DIN connector
    A. 6-pin PS/2 connector
    A. USB Port
    Explanation
