For example, graphics tablets capture analog stylus strokes written on a pad and convert them to digital data. These are mostly used by graphic artists to capture hand-drawn images. Smart card readers are used as an authentication method. A smart card, which contains an embedded microchip, is inserted into the reader. The reader then scans the chip, verifies its contents, and authenticates the user. Smart card readers can be stand-alone devices or integrated with other peripherals (such as a keyboard). Biometric scanners are used as a form of authentication. They are able to scan users' unique physical features and use them to verify their identity.

You would like to reduce the time it takes to move from one computer to the next, and you would like to use only one keyboard, one monitor, and one mouse for all three computers. Which of the following devices BEST allows this type of setup? Router KVM DVI USB hub Explanation A KVM (keyboard, video, mouse) switch would allow you to control all three computers with one keyboard, one monitor, and one mouse. The KVM switch has multiple input groups, and each group accepts keyboard, video, and mouse connections from a single computer. A single output group connects to the shared input/output devices. Buttons on the KVM switch or keyboard shortcut combinations allow you to toggle the input/output devices between computers. A USB hub allows multiple USB-compatible devices (up to 127) to be connected to a single USB connection, but the hub does not connect to or control multiple PCs. A router is a networking device that connects multiple networks. DVI is a standard for connectors to digital video cards.

HDMI splitter VGA splitter USB multi-port hub KVM switch Explanation A KVM (keyboard, video, and mouse) switch allows multiple computers to use a single keyboard, mouse, and monitor. KVM switches have multiple input groups. Each group accepts keyboard, video, and mouse connections from one computer. A single output group connects to the shared peripheral devices. Buttons on the KVM switch are used to toggle between each connected computer. Some KVMs allow you to switch devices using a special keyboard key combination. An HDMI splitter is used to take a single source (such as a computer) and distribute that HDMI signal to multiple output devices, such as monitors. A VGA splitter is a cable or device that allows you to separate a video signal into multiple connections and connect those individual signals to multiple devices. A multi-port USB hub is a device that expands a single Universal Serial Bus (USB) port into several so that there are more ports available to connect devices to a host system, similar to a power strip. 9/11/2019, 8:25 PM 4 of 4 References TestOut PC Pro - 4.1 Peripheral Devices [e_dev_pp6.exam.xml Q_PER_DEVICES_KVM_02] Question 6: Incorrect What type of peripheral device is typically found on a laptop computer and allows the user to control the cursor with a finger?

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
