Installing And Supporting I/O Devices

A Hi-Speed USB port is 40 times faster than an Original USB port running at 12 Mbps. This means that the Hi-Speed USB port has a data transfer rate of 480 Mbps, which is 40 times greater than 12 Mbps.

A FireWire 800 port is two times faster than a FireWire 400 port. This means that the FireWire 800 port has double the data transfer speed compared to the FireWire 400 port.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

The correct answer is 5-pin round DIN connector, 6-pin PS/2 connector, and USB Port. These are the three types of ports that a keyboard might use. The 5-pin round DIN connector and 6-pin PS/2 connector are older types of ports that were commonly used for connecting keyboards to computers. The USB port is a more modern and widely used port that allows for easy plug-and-play connection of keyboards to computers.

A FireWire 800 port has 9 pins. FireWire 800 is a type of high-speed serial bus commonly used for connecting devices such as external hard drives, digital cameras, and video cameras to a computer. The 9 pins in a FireWire 800 port are used for transmitting data, providing power, and grounding. This port is designed to provide faster data transfer rates compared to previous versions of FireWire, making it suitable for transferring large files and streaming high-quality video.

The speed for Hi-Speed USB is 480 Mbs/second. This means that data can be transferred at a rate of 480 megabits per second. This high-speed USB standard allows for faster and more efficient data transfer between devices such as computers, printers, and external storage devices. It is an improvement over the previous USB standards and enables quicker file transfers and faster charging of compatible devices.

A touch screen might use USB and Serial ports. USB ports are commonly used for connecting various devices, including touch screens, to a computer. Serial ports, on the other hand, are older and less commonly used, but some touch screens may still use them for communication with a computer.
