Mark has purchased a new working USB webcam. He connects the webcam to a USB port on his computer and finds that the computer does not detect it. He connects other working USB devices to the CompTIA port and discovers that the USB port is not functioning. What should Mark do first to resolve the issue?
A. Verify that the USB functionality is enabled in the BIOS.
B. Purchase another model of the USB webcam.
C. Change the computers motherboard.
D. Replace the USB port wires with a new one.
Correct Answer: A

In order to resolve the issue, Mark should first verify that the USB functionality is enabled in the BIOS on the motherboard. The BIOS has an option for enabling and disabling the USB functionality. If this functionality is disabled from the BIOS, the USB ports on the computer will not work. Universal Serial Bus (USB) is a high speed bus standard developed by Compaq, IBM, DEC, Intel, Microsoft, NEC, and Northern Telecom. It provides the Plug and Play capability of Windows to external hardware devices. USB supports hot plugging, which means that a USB device can be installed or removed while the computer is running. A single USB port can be used to connect up to 127 peripheral devices, such as CDROM drives, tape drives, keyboards, scanners etc. USB 1.1 has a maximum data transfer rate of 12 Mbps, whereas USB 2.0 has a maximum data transfer rate of 480 Mbps. USB 2.0 is fully backward compatible with USB 1.1. Answer option C is incorrect. There is no need to change the motherboard, as the problem is most probably due to the BIOS setting for USB functionality. Answer option B is incorrect. Purchasing another model of the USB webcam will not help resolve the issue, because the problem is not with the webcam. Answer option D is incorrect. It is possible that the USB port wires are bad. However, this rarely happens.
Which of the following defines power management for various types of computers and peripherals?
Correct Answer: C

Answer option C is correct.
The Advanced Configuration and Power Interface (ACPI) is a power-management specification developed by Intel, Microsoft, and Toshiba. It enables an operating system to control the amount of power supplied to each device attached to a computer by turning off peripheral devices when they are not in use. It defines power management on a wide range of mobile, desktop, and server computers and peripherals. It also enables manuurers to produce computers that FC0-U51 pdf automatically power up as soon as a user touches the keyboard. Answer option B is incorrect. HDMI stands for High-Definition Multimedia Interface. It is a standard, uncompressed, and all-digital audio/video interface. HDMI is capable of delivering the highest quality digital video and multi-channel digital audio on a single cable. It provides an interface between any audio/video sources, such as a DVD player or a computer and a digital television (DTV) or video monitor.

HDMI transmits all ATSC HDTV standards and supports 8-channel digital audio, with extra bandwidth to accommodate future enhancements. HDMI has two types of connectors: Type A and Type B. Type A and Type B connectors use 19 pins and 29 pins, respectively. The Type B connector is designed for very highresolution displays that are expected in near future. Answer option D is incorrect. Peripheral Component Interconnect (PCI) is a high-performance, 32-bit or 64-bit bus designed to be used with devices that have high bandwidth requirements, such as the display subsystem.

Answer option A is incorrect. PCI Express (PCIe), also known as 3rd Generation I/O (3GIO), is a type of computer bus. It is a new I/O bus technology that has more bandwidth than PCI and AGP slots. It uses two low-voltage differential pairs, at 2.5Gb/s in each direction. It is designed to replace PCI and AGP expansion slots. The FC0-U51 exam bus is available in several different bus widths: x1, x2, x4, x8, x12, x16, and x32. PCIe is able to transfer data in both directions at a time. PCIe hardware will work on operating systems that support PCI.

You want to add broadband wireless access to a laptop. What type of card will you use to accomplish this?
A. Network interface card
B. PCI card
C. Aircards
D. MCA card
Correct Answer: C

Aircards are used to provide wireless broadband access. They are often PCI Express type cards. Answer option A is incorrect. A NIC would help in accessing the local network, but not broadband wireless. What is a network interface card (NIC)?
A network interface card (NIC) is a computer circuit board or card installed in a computer. It provides physical connection between a computer and the network. Network interface cards provide a dedicated, full-time connection to FC0-U51 vce a network.
Answer option D is incorrect. MCA is a very outdated expansion type for PC’s. Answer option B is incorrect. PC’s use PCI, laptops use PCI mini express.

You are responsible for the wireless network at your company. You have been asked to create SSID’s for wireless routers. What are the limits on an SSID?Each correct Answer represents a complete solution. Choose two.
A. It is not case sensitive.
B. It must be 32 or fewer characters long.C. It can only contain letters, not numbers.
D. It is case sensitive.
E. It must be 64 or viewer characters long.
Correct Answer: BD

Answer An SSID can be a maximum of 32 characters long and is case sensitive. What is SSID? SSID stands for Service Set Identifier. It is used to identify a wireless network. SSIDs are case sensitive text strings and have a maximum length of 32 characters. All wireless devices on a wireless network must have the same SSID in order to FC0-U51 dumps communicate with each other. The SSID on computers and the devices in WLAN can be set manually and automatically. Configuring the same SSID as that of the other Wireless Access Points (WAPs) of other networks will create a conflict.

Read more: A network administrator often uses a public SSID that is set on the access point. The access point broadcasts SSID to all wireless devices within its range. Some newer wireless access points have the ability to disable the automatic SSID broadcast feature in order to improve network security. Answer options E and A are correct. The max length is 32 characters, not 64 and SSID is case sensitive. Answer option is incorrect. An SSID can contain numbers and letters.
