Figure 27-29 shows an example of the Secure Desktop/Vault, or logical desktop. Notice the buttons on the right that allow you to switch to the physical computer desktop or close down the Secure Session. Notice the lock picture in the middle of the screen. In the taskbar (not seen in the figure), you ll see a yellow icon indicating that the Secure Desktop is secure.

content, are restricted. You can also restrict the maximum object size that can be posted with the POST method (post-max-size command) and the maximum object size that can be uploaded (upload-max-size command). The default is 2,147,483,647 bytes (over 2 GB!) for all three.

af xed to the substrate. This same process is followed for the second substrate, which also contains two layers of data, providing a total capacity of 17.9GB. As with a DVD-10 disc, this type of disc must be turned over in the player or the DVD-ROM drive in order to access the data on the second side. Similarly, neither surface can be printed with a label, since it must offer clear access to the laser for data reading.

Chew Toy s weapon is a rotary spinning mass. The design is simple: two milling saws on each side of the prow are driven by a chain sprocket mechanism. As you can see in Figure 14-1, a large chain sprocket was used; it takes chain reduction

Candlelight is another wonderful light source for available-light photography. The light from a candle is warm and golden, much like the light you ll find early in the morning or late in the afternoon.

The instrumentation system includes a key switch, throttle control, and monitoring wiring. Key switch wiring, controlled by an ignition key, routes power from the accessory battery or DC-to-DC converter circuit to everything you need to control when your EV is operating: headlights, interior lights, horn, wipers, fans, radio, etc. Throttle control wiring is everything connected with the all-important throttle potentiometer function. Monitoring wiring is involved in remote sensing of current, voltage, temperature and energy consumed, and routing to dashboard-mounted meters and gauges. Let s take a closer look at these low-voltage components.

one or more outer electrons from each atom to begin orbiting both nuclei of the atoms. Electrons orbiting both nuclei are said to be shared. Covalent bonds always involve sharing pairs of electrons (one from each atom for every pair of electrons that is shared). Both nuclei feel an attractive force toward the shared electrons. Like two people wrapped in a single blanket, the force between the shared electrons and the two nuclei is the chemical bond that holds the two atoms together. In practice, the electrons in a covalent bond may not be equally shared by both atoms. One of the atoms may have a stronger pull on the electrons than the other. This can be because one atom has a more positively charged nucleus or because its nucleus is more exposed to, or closer to, the shared electrons. When this happens, the electron cloud of the shared electrons leans closer to the atom with the stronger pull, giving that atom a slightly negative charge. The other atom will have a slightly positive charge. In such a case the covalent bond is said to be polar, meaning that the electric charge is not evenly distributed across the bond. See Fig. 6-1.

Wi-Fi Protected Access (WPA) An encryption standard for 802.11 wireless networks. The final version of WPA is known as WPA-2. See also 802.11. wide area network (WAN) A network whose size ranges from regional to international. This term is also used to describe a single point-to-point connection between two distant locations (a WAN connection ). wideband code division multiple access (W-CDMA) An airlink standard for wireless communications between mobile devices and base stations. Wired Equivalency Protocol (WEP) An encryption standard for 802.11 wireless networks. WEP has been compromised and should be replaced with WPA-2. See also 802.11, Wi-Fi Protected Access (WPA). wireless USB (WUSB) A short-range, high-bandwidth standard wireless communications protocol used to connect computer peripherals. work breakdown structure (WBS) A logical representation of the high-level and detailed tasks that must be performed to complete a project. worm A type of malware containing stand-alone programs capable of human-assisted and automatic propagation. X.25 A common carrier standard for transporting packets from one station to another. X.25 has been replaced by Frame Relay. See also Frame Relay. Zachman Framework An enterprise architecture framework used to describe an IT architecture in increasing levels of detail.
