This simplifies program development because the programmer need only worry about manipulating the socket and can rely on the operating system to actually transport messages across the network correctly.
Spider or Robots
It is a program that most of the major search engines on the web use. Spiders visit web sites and read their pages and other information in order to create entries for a search engine index. Spiders are typically programmed to visit sites that have been submitted by their owners as new or updated. Entire sites or specific pages can be selectively visited and indexed. Spiders usually visit many sites in parallel at the same time, their "legs" spanning a large area of the "web." Spiders can crawl through a site's pages in several ways. One way is to follow all the hypertext links in each page until all the pages have been read.

Depending on the size of the site, the Webmaster might be responsible for any of the following: Making sure that the web server hardware and software is running properly, designing the web site, creating and updating web pages, replying to user feedback, creating CGI scripts, monitoring traffic through the site.
A web site.
A computer that delivers (serves up) web pages. Every web server has an IP address and possibly a domain name. For example, if you enter the URL http://www.sterlink.net/index.html in your browser, this sends a request to the server whose domain name is www.sterlink.net. The server then fetches the page named home.asp and sends it to your browser.
Web Site Creation
A phase in creating a web presence, where the site navigation, images and content are determined and a developer writes the code.
An Internet utility that returns information about a domain name or IP address. For example, if you enter a domain name such as sterlink.net, whois will return the name and address of the domain's owner.

It enables designers to create their own customized tags to provide functionality not available with HTML. For example, XML supports links that point to multiple documents, as opposed to HTML links, which can reference just one destination each.
