Cable signal strong link with the temperature. According to professional departments test, the temperature is increased by ten degrees Celsius, the signal cable attenuation to increase 4%. This means 40 degrees Celsius 92.6 m cable signal attenuation 100 meters and 20 degrees Celsius the same cable signal attenuation. Therefore, the temperature on the effects and signal attenuation is much larger than many other fixed factors. According to the relevant tests, in the summer, a number of concrete structural layer of the cable temperatures as high as 40 degrees. In some companies, may be higher. Shows the impact of temperature on the cable is very great. We have set up corporate networks, the need for us to buy the cable to the temperature of the test. Perhaps we did not test the low temperature under conditions of cable performance. But, obviously, we can at a high temperature, some of the wire to test the performance. For temperature, we mainly test, in high temperatures, outside the wire will significantly soften the skin and so on.
Mozilla and Google in August this year, renewed in 2011 to launch the Google Chrome Web browser made a week ago. Baker said in an interview, Mozilla continued to observe the Chrome but not particularly worried. Search for cooperation between the two sides similar to Googles AdSense program, which is the site published in Googles advertising revenue with Google to share relevant, but Google has many similar partnerships. She stressed: "Our market share continues to grow, and we expect to maintain healthy growth." Windows Vista has a security vulnerability that hackers could exploit the vulnerability in the Windows Vista operating system installed on a computer hidden rootkit or perform denial of service attacks. This vulnerability is Austrias Thomas Wentworth security company Phion Trey Turner discovered and released on Friday. Wen Trey Turner said, Phion October this year has notified Microsoft of the flaw, but he thinks may have to wait until the next Vista service pack is released to fix this vulnerability.
