FC0-U41 Question #77: Real Exam Question with Answer & Explanation

Question

Options

• ASD Card
• BVideo Capture card
• CExpressCard
• DSmart card

Explanation

A video capture card is a computer component that allows television signals to be received by a computer. It also allows television programs to be recorded onto a hard disk. Most TV tuner cards also function as video capture cards. Video capture cards are a class of video capture devices designed to plug directly into expansion slots in personal computers and servers. These cards comply with one of the popular host bus standards including PCI, newer PCI Express (PCIe), or AGP bus interfaces. Answer option A is incorrect. Secure Digital (SD) card is a non-volatile memory card format used in portable devices such as mobile phones, digital cameras, and handheld computers. SD cards are based on the older MultiMediaCard (MMC) format, but they are a little thicker than MMC cards. Generally an SD card offers a write-protect switch on its side. SD cards generally measure 32 mm x 24 mm x 2.1 mm, but they can be as thin as 1.4 mm. The devices that have SD card slots can use the thinner MMC cards, but the standard SD cards will not fit into the thinner MMC slots. Some SD cards are also available with a USB connector. SD card readers allow SD cards to be accessed via many connectivity ports such as USB, FireWire, and the common parallel port. Answer option C is incorrect. ExpressCard, a new standard introduced by PCMCIA, is a thinner, faster, and lighter modular expansion for desktops and laptops. Users can add memory, wired or wireless communication cards, and security devices by inserting these modules into their computers. ExpressCard slots are designed to accommodate modules that use either Universal Serial Bus (USB) 2.0 or the PCI Express standard. ExpressCard modules are available in two sizes, i.e., 34 mm wide (ExpressCard/34) and 54 mm wide (ExpressCard/54). Both modules are 75 mm long and 5 mm high. An ExpressCard/34 module can be inserted in either a 54 mm slot or a 34 mm slot, but an ExpressCard/54 requires a Universal (54 mm) slot. However, an extender can be used with ExpressCard/34 slot to connect the ExpressCard/54 module from outside of the computer. Both the modules are identical in performance. They take full advantage of the features of the PCI Express or USB 2.0 interfaces. The only difference between them is that the ExpressCard/54 form-or, due to its larger surface area, allows for greater thermal dissipation than does an ExpressCard/34. As the performance does not vary with module size, module developers usually prefer to fit their applications into the smaller ExpressCard/34 form or. But some applications, such as SmartCard readers, and CompactFlash readers, require the extra width of an ExpressCard/54 module. Answer option D is incorrect. A smart card is a credit card-sized device used to securely store personal information such as certificates, public and private keys, passwords etc. It is used in conjunction with a PIN number to authenticate users. In Windows 2000/2003, smart cards are used to enable certificate-based authentication. To use smart cards, Extensible Authentication Protocol (EAP) must be configured in Windows 2000/2003.
