B. FireWire 800 can span 100 meters when implemented over fiber-optic cable. Over copper cable, it’s limited to 4.5 meters, like FireWire 400.

<p>2</p>

A. A mini-ITX motherboard is a 6.7″ square. Nano-ITX motherboards are 4.7″ square, pico-ITX motherboards are 3.9″ × 2.8″, and mobile-ITX motherboards are 2.4″ square.

<p>3</p>

A, C. A 32-bit OS can run on either a 32-bit or 64-bit processor, although you will not be able to fully utilize the 64-bit processor’s capabilities with a 32-bit OS. A 64-bit OS will run only on a 64-bit processor.

<p>4</p>

A, B, C. The DC power supply (DCPS) converts house current into three voltages: +5VDC and –5VDC for the logic circuitry and +24VDC for the paper-transport motors.

<p>5</p>

A. Three RCA-like connectors at the end of a cable indicate a component video cable.

<p>6</p>

A. The two most popular methods of manufacturing LCD panels are twisted nematic (TN) and in-plane switching (IPS). Of the two, IPS is regarded as having the best color representation in all angles, while TN is faster and less expensive. LED and plasma are not types of LCD panels.

<p>7</p>

A. A mini-DIN 6 connector is a round connector often called a PS/2 connector. It’s historically used for a keyboard or a mouse. If you have only more modern USB peripherals, you can buy a PS/2 to USB adapter to plug them into one of these ports.

<p>8</p>

D. A hybrid hard drive is a combination of a conventional magnetic hard disk drive and solid-state storage. The goal is to increase access speed for commonly accessed data while still providing larger capacity similar to a conventional HDD.

<p>9</p>

C. Thicker paper can cause paper jams, especially in printers with curved paper paths. Paper that is too thin may not get picked up by the printer rollers at all.

<p>10</p>

C. TCP printing allows client with different OSs to send jobs directly to printers without worrying about intra-OS conflicts. Bonjour and AirPrint are both Apple services, and virtual printing allows you to print output to documents such as PDF files. Whenever sharing printers for remote printing, be sure to set proper user authentication on the print device.

<p>11</p>

B. A CAT6a cable is a network cable, and you are most likely to find an RJ-45 connector at the end of it. RJ-11 connectors are for phone lines. BNC connectors are network connectors but are typically used with coaxial cable. SATA connectors are hard drive connectors.

<p>12</p>

A. The connector shown is a DVI connector, used for digital video.

<p>13</p>

B. Thermal printers will often use a roll of paper as opposed to individual sheets. Fax machines may use thermal technology, but a fax machine in itself is not a printer technology.

<p>14</p>

A. Parity checking is a rudimentary RAM error-checking scheme that offers no error correction.

<p>15</p>

A, C, D. Laser printers need toner cartridges, impact printers need ink ribbons, and ink-jet printers use ink cartridges. Thermal printers heat up paper to produce images.

<p>16</p>

A. An imaging drum is a photosensitive drum that can hold a charge if it’s not exposed to light. It is dark inside an EP printer, except when the laser scanning assembly shines on particular areas of the photosensitive drum.

<p>17</p>

B. A micro-ATX motherboard is a 9.6″ square. ATX motherboards are 12″ × 9.6″, mini-ITX motherboards are 6.7″ × 6.7″, and pico-ITX motherboards are 3.9″ × 2.8″.

<p>18</p>

D. Resolution is the number of pixels used to draw a computer screen. Refresh rate determines how many times per second the screen can be redrawn. Frame rate tells you how many frames per second the original content was filmed in. Aspect ratio defines the dimensions (width × height) of an image.
