Introduction of Internet
The Internet is a tool that connects millions of computers together, allowing them to communicate with
each other. Information is not "stored" on the Internet. Rather, information is stored on host computers;
the Internet is simply a tool that allows you to access the information stored on someone else’s computer.
Sometimes the Internet is compared to a HUGE worldwide plumbing system connecting computers
together.
The Internet is a tool that allows you to do these things:
 Send and receive electronic mail
 Access the World Wide Web
 Remote access (Use one computer to access information stored on another computer)
 Transfer files (Rapidly send and receive files between computers)

Generally the first page retrieved when accessing a Web site.
Usually a "home" page acts as the starting point for a user to
access information on the site. The "home" page usually has
some type of table of contents for the rest of the site
information or other materials. When creating Web pages, the
"home" page has the filename "index.html," which is the
default name. The "index" page automatically opens up as the "home" page.
The term home page is used to refer to the page that is the default page of any website. It is the
main page of a complex website.
3. Hyperlink:
