I.T. CHAPTER 6 What is the difference between a docking station and a port replicator? A docking station has fewer ports. A docking station may have PCI slots for expansion cards and speakers. A docking station may have a built-in display. A docking station has a universal connector so that it can be used with all laptops. Which display technology is most commonly found in modern laptop computers? CRT LED plasma LCD Which task must be completed first for a technician to be able to configure power management states using Windows XP? APM power management mode must be configured in the BIOS before ACPI can be used to configure power. ACPI power management mode must be enabled in the BIOS before Windows XP can be used to configure power management. APM power management mode must be disabled in the BIOS so that Windows XP can be used to configure power management. All power management settings must be disabled in the BIOS so Windows can be used to manage ACPI. Which two laptop ports are used primarily for communication and network connectivity? (Choose two.) Ethernet modem parallel DVI
Which three components commonly connect to USB or FireWire ports? (Choose three.) camera AC adapter PC Card printer scanner graphics adapter What is the major difference between desktop and laptop motherboards? Desktops use the AT form factor while laptops use the mini or baby AT form factor. Desktop motherboards typically have a standard form factor and are interchangeable while laptop motherboards are proprietary. Desktops have a variety of expansion and RAM slot designs while laptops have standard expansion and RAM slot designs. Currently there is no significant difference in the motherboard form factors for the desktop and laptop. Refer to the exhibit. What is the correct order of steps to remove a laptop battery? 3, 2, 4, 1
2, 3, 4, 1 2, 4, 1, 3 3, 2, 1, 4 What is the benefit of using CPU throttling in laptops? It reduces the processing time needed by end-user applications. It reduces CPU power consumption and heat production. It reduces the amount of CPU resources needed by system applications. It avoids the need to increase the clock speed of the laptop processor. Which two characteristics make laptops a better choice than desktop computers? (Choose two.) mobility functionality size OS installed compatibility Which three components are interchangeable between desktop and laptop computers? (Choose three.) PC ExpressCard hard disk PCI sound card printer scanner
USB flash drive Which type of interface do current laptops use to achieve similar expansion capabilities as desktops? CardBus PC ExpressCard ISA PCI Refer to the exhibit. Which two form factors are supported by the devices shown in the graphic? (Choose two.) 30-pin 34-pin 43-pin 45-pin 54-pin Which name is given to the collection of settings that control the power settings of a
laptop? current setups energy settings hibernation profiles power profiles power schemes Which two devices are commonly hot-swappable on laptops? (Choose two.) Integrated LCD screen CPU chip PC Card RAM USB Drive Which generation of cell-phone standards was the first to deal with how to send and receive text, photographs, and video? first second third fourth Which type of questions would a technician initially ask to gather information to help solve the problem? categorical
closed directed multiple-choice open What is meant by a laptop device being hot-swappable? The device does not need a driver to interface with the computer OS. The laptop does not need to be powered off to install or remove the device. The device can be connected using more than one type of port. The device can interface with the laptop wirelessly. Where can a technician change the power schemes on a laptop running Windows XP? Select Advanced Settings from within the BIOS. Select Power Options from within the Control Panel. Select Power from within Administrative Tools. Select Configure Power Settings from within Computer Management Which two devices can be individually configured within Windows XP to power off after the laptop has been idle for a given period of time? (Choose two.) optical drive disk drive fan monitor wireless NIC
Which internal laptop component may be designed as a hot-swappable device? CPU LCD screen optical drive RAM touch pad A user has connected a digital projector to the external monitor port on a laptop computer, but the projector indicates that there is no RGB signal. What should the user try first to resolve the problem? Connect the projector to the s-video port. Press the function key that will redirect the video output to the external monitor. Try a different laptop. Try a different projector. What is the proper way to clean optical drives? Spray ionized solution inside the drive. Use an electrostatic vacuum cleaner. Blow the dust with compressed air from the inside. Use a cleaning disc for optical drives. Which two actions should be performed to clean the surface of CDs and DVDs? (Choose two.) Use a lint-free cotton cloth. Use a cotton ball. Use a household cleaning solution.
