Many web pages prevent you from saving QuickTime movies to your hard drive. Here are some hints to get you started. Many web pages now exist for viewing QuickTime movies. You enjoy viewing and watching the movies; however, you cannot find out how to download them directly to your hard drive. Based on the skill level of the web designer, it is possible to prevent users from directly downloading the movies’ files. Fortunately, however, most web designers do not go to such trouble. With a few simple hints, you have a good chance of directly downloading it. Methods: 1.Right-click and Save Target As If there is a direct link on the web page to the movie file, then it is very easy to download. – Right click on the direct link to the movie file (*.mov). – Select Save Target As. – Name it and save it. 2.Find the link hidden in the source Most web designers do not give a direct link; however, you can still find the link in the source code. – Navigate to the page on which the movie is playing. – Click View menu. – Click Source. – Notepad is open; click Edit menu. – Select Find. – In the text box type the following: .mov andmake sure you include the period. – Typically the end of the url will be highlighted. The URL will like this, for example: embed src= "http://www.blahblahblah.org/movies/hah_faptastic1.mov" border="0" bgcolor="#212121" controller="true" target="myself" pluginspage="http://www.apple.com/quicktime/download/" loop="FALSE" autoplay="true" height="262" width="320"> – Highlight and copy the URL part of the following: http://www.blahblahblah.org/1/graphics/movies/hah_faptastic1.mov – Paste this URL into your browser address bar, and click GO. – When the film has completely loaded, click the File menu in your browser. – Select Save As. – Name and save your movie file. Unfortunately, these two common methods will not work for all web applications. Many companies that developed highly complex methods for hiding the source quicktime files to prevent easy downloading.

The network administrator assigned 10.0.1.128/25 to the Admin subnet. The Sales subnet is given 10.0.1.192/26. What will be the result of this addressing scheme?
Because RIPv2 does not support VLSM, the subnet masks will not be allowed. The subnets will not have enough host addresses for the given network requirements. The subnets overlap and will be rejected by the router. The router will support the addressing scheme.

Refer to the exhibit. A network engineer is summarizing the two groups of routes on router R1 shown in the exhibit. Which summarization will work for all the subnets?
Refer to the exhibit. A network technician enters the static route in R1 needed to reach network 10.1.1.0/24. A ping from the S0/0/0 interface on R1 to host B fails. The technician begins testing the network and has the following results:
1. pings from R1 to the S0/0/0 interface on R2….successful 2. pings from R1 to the Fa0/0 interface on R2….successful 3. pings from host B to hosts on the 10.1.1.0/24 network….successful 4. pings from host B to the Fa0/0 interface on R2….successful 5. pings from R2 to host B….successful.

Talk about your hot phone. A truck containing 22,500 LG G2 smartphones was stolen on the way to its destination in Louisville, Ky., CNET has learned. The phones were on their way to Sprint, which is expected to launch its version of the G2 early next month.
The phones were stolen at 6:30 p.m. Thursday at a truck stop in Gary, Ind., an LG representative confirmed to CNET. The driver left the truck for a bathroom break, and upon returning, found the vehicle missing. The Indiana and Illinois state police have been contacted, as well as the FBI. The G2 is LG's flagship device, and has stood out in the market with its unique volume and power button located at the back of the smartphone, right under the camera. It's a controversial change that has met with mixed reviews. The G2, like other flagship phones such as the Galaxy S4, iPhone 5S, and HTC One, was released on multiple carriers, with Sprint among the later carriers to sell the device.
