Millions of Web sites and billions of Web pages, huh? I
guess I really hadn't thought about it. I've definitely thought of the Internet
as infinite but I haven’t ever tried to associate a numerical value to it. With new
pages continuously being added to existing sites, it’s no surprise that the
number is immeasurable. Shelly and Campbell tell us that “Web sites can consist
of a single Web page or thousands of pages.” (38) From a business perspective,
sites can be used to sell products or services. There are personal Web sites
that can be used for communication purposes. A primary Web page on a Web site
is called a Home Page. The web site itself could be a singular page or have multiple pages,
links or tabs so navigation is easier. These pages, links, or tabs would allow
the reader to review general information about the site and should also include
frequently asked questions (FAQs) for problem resolution.
I've never heard of Yahoo! referred to as a Web Portal (AKA
portal). A portal “… is a special
type of Web site that offers a doorway to a vast range of content and
services.” (39) Portals provide a place for those opening browsers and can
feature news, weather, reference tools, etc. Web pages need to be eye catching
in order to keep viewers interested (kind of like our blogs!). Things like
logos, images, links, and advertisements can be found on Web pages. These
things can frequently change.
“A single Web server can store or host many small
Web sites.” (41) Client/server computing is a process by which a Web browser
(or client) sends a request to a Web server where the page is stored. The
server should respond “… by sending a copy of the Web page to the browser.”
(41) A client is defined by Shelly
and Campbell as “… an application that runs on computer, such as a personal
computer, and requests resources or services from another computer.” Whereas a server is defined as: “… a computer
that ‘serves up,’ or provides, the requested resources or services.” (41)
Servers can be in the same location or a location far removed from the main
location(s).
