How do you make bootable disk of xp with iso image?

If your iso is a precise image of a bootable cd/dvd, you need only a program to burn it. PowerIso can help with that. It's shareware but allows to burn bootable isos while it's trial.

If your iso is not bootable, you will have to make it so. Again PowerIso allows to do so, but you will have to find full working version. Anyway, you will need to find a bootable cd/dvd of the same software (OS and so) to extract the boot sector. After that you edit the current iso by integrating the boot sector to the iso and save as a another iso.

What does www stand for in computer terms?

The World Wide Web (commonly abbreviated as "the Web") is a system of interlinked hypertext documents accessed via the Internet. With a Web browser, one can view Web pages that may contain text, images, videos, and other multimedia and navigate between them using hyperlinks. Using concepts from earlier hypertext systems, the World Wide Web was begun in 1992 by the English physicist Sir Tim Berners-Lee, now the Director of the World Wide Web Consortium, and Robert Cailliau, a Belgian computer scientist, while both were working at CERN in Geneva, Switzerland. In 1990, they proposed building a "web of nodes" storing "hypertext pages" viewed by "browsers" on a network,[1] and released that web in 1992. Connected by the existing Internet, other websites were created, around the world, adding international standards for domain names & the HTML language. Since then, Berners-Lee has played an active role in guiding the development of Web standards (such as the markup languages in which Web pages are composed), and in recent years has advocated his vision of a Semantic Web. Cailliau went on early retirement in January 2005 and left CERN in January 2007. The World Wide Web enabled the spread of information over the Internet through an easy-to-use and flexible format. It thus played an important role in popularising use of the Internet,[2] to the extent that the World Wide Web has become a synonym for Internet, with the two being conflated in popular use

The constant staring at a screen and not moving for multiple hours can have negative effects on the eyes.

Besides from that, the lack of movement and the slouch in posture can cause problems with your lower back, gluteal region, and hamstrings. Lastly, any exposure to light stimuli, such as the computer screen, will make falling asleep immediately after much harder, since your mind is still processing information.
