what is windows registry structure?
What is windows registry structure?
*Windows Registry Structure - is when you open it up with a Registry Editor utility like REGEDIT.EXE or REGEDT32.EXE. If you’ve never opened the Registry before, you might be surprised and comforted by its familiar-looking layout. Its hierarchical data structure is much like the data structure you see everyday in Windows Explorer, except here the tree structure units are keys, subkeys, and values rather than directories, subdirectories, and files.

Difference Between windows xp and windows 9x
What are the difference between windows 9x and windows xp?
* Windows 9x- is a term used to describe the DOS-based Microsoft Windows operating systems, Windows 95, Windows 98, and Windows Me, which were produced in the 1990s.
*Windows NT- is a family of operating systems produced by Microsoft, the first version of which was released in July 1993. It was originally designed to be a powerful high-level language-based processor-independent multiprocessing multiuser operating system with features comparable to Unix to complement workstation versions of Windows that were based on MS-DOS until 2001.
*Why windows XP belongs to NT family??
*Windows XP- is the successor to both Windows 2000 and Windows Me, and is the first consumer-oriented operating system produced by Microsoft to be built on the Windows NT kernel and architecture.

What is DNS
* Domain name system- (DNS) stores and associates many types of information with domain names; most importantly, it translates domain names (computer hostnames) to IP addresses. It also lists mail exchange servers accepting e-mail for each domain. In providing a worldwide keyword-based redirection service, DNS is an essential component of contemporary Internet use.
* Top-level domain- (TLD) is the last part of an Internet domain name; that is, the letters which follow the final dot of any domain name. For example, in the domain name www.website.com, the top-level domain is com (or COM, as domain names are not case-sensitive).
* Hostname- (occasionally also, a sitename) is the unique name by which a network attached device (which could consist of a computer, file server, network storage device, fax machine, copier, cable modem, etc.) is known on a network. The hostname is used to identify a particular host in various forms of electronic communication such as the World Wide Web, e-mail or Usenet.

Introduction on Microsofts
what is the process to install windows xp?
Find the step by step introduction on Microsoft's web site?
* There are no fewer than five places where the country/language/keyboard layout must be set. With most versions of Linux it is usual for the country to be specified early in the install process, and then the user is asked to confirm this choice (instead of selecting from a long dropdown list) when it comes to specifying language, keyboard layout etc. The regional settings section is also very poorly laid out and inexperienced users (which means most people since an average user rarely performs a Windows reinstallation) often don’t realise that the country selection has to be made several times and end up with a computer set for "US English" keyboard layout even when they live outside the USA.
* The choice of default timezone setting (UTC -8, the timezone of the US state where Microsoft's head office is based), when a far more logical default option would be UTC, or even the most populous timezone of the country the computer is to be used in (which is specified earlier in the install process).
* The choice of "Letter" rather than "A4" as a default printer setting even when the installation is configured for use outside the USA (where ISO standard paper size predominate).
