Amazing Facts

Space Plane
The problem with multi-stage rockets is that they can only be used once. When the stages fall back to Earth, they burn up in atmosphere and are destroyed. This is why scientists in several countries are trying to develop a reusable “space-plane” that takes off horizontally. While in earth's atmosphere, it would take in air to burn fuel (like normal airplane). When in space, where there is no air, it would burn liquid hydrogen and oxygen (like a rocket).

Computer Tips-9

Tip 1: Restrain the scripting behavior
Web page scripts are responsible to spread viruses, and worms. If you are using Internet Explorer (IE) you can take a protective measure by controlling the scripting behavior of your browser. In Windows XP follow these steps…
Open IE
Click Tools>Internet Options>Security
Under 'Select a Web content zone', choose the Earth icon
Click the Custom Level
Carefully observed viewed information. You encountered three options such as Disable, Enable, and Prompt. If you realized about some options create risk, disable it or take a safe stand by selecting the prompt. Restrain the script to execute also generates problem for some web pages. To bypass this unwanted situation add these sites and services to IE's Trusted Sites list. Again, follow these steps…
Open IE
Click Tools>Internet Options>Security
Select the Trusted Sites icon, click Sites, and then enter the URLs one at a time.
Uncheck 'Require server verification (https:) for all sites in this zone'
Click Ok

Tip 2: Wipe out unneeded files
Unneeded files grab valuable memory space that results a downgraded performance. You can eliminate this problem by the Disk Cleanup feature built in Windows XP. Follow these steps…
Click Start>All Programs>Accessories>System Tools>Disk Cleanup
Select the drive you want to clean
XP will analyze your files and shows a hit list. Check the boxes next to the categories you want to discard. The More Options tab offers you several more cleanup choices. The System Restore cleanup option, in particular, can clear lots of disk space by erasing old restore points.
