In this web primer we will discuss
various web development technologies and methods that can be used to create
database driven dynamic content web pages, e-commerce portals and specific web
applications:
You have heard a lot about the Web
and you have used it; you may have even worked with building some Web pages. But
how does it all fit together? What does it all mean? What about Netscape, HTML,
HTTP, TCP/IP, forms, URLs, Navigator, Microsoft, Internet Explorer, Java,
JavaScript, CGI, etc. This primer will introduce you to some of the basic
concepts behind the Web, HTML. It is not meant to be an in-depth review of all
the inner workings of every aspect of Internet technology. It does discuss some
history, HTML, scripting, browsers, forms and various web technologies to put
you on solid foundation for building your web pages.
The most of this website and lot of
other commercial websites are developed using similar technologies. The
discussed technologies are powerful and enable you to create dynamic database
driven web pages. A language like the one used in Active Server Pages is
the one that necessitates use of a special web server running Windows operating
system.
New Internet world or the
cyberspace is rapidly growing and together we will tackle the basics so we can
begin building truly activated Internet pages . Probably the first thing to
remember when getting started is that the World Wide Web is a subset of the
Internet. The Internet first appeared in the 1970s as an experiment of the
United States government's Advanced Research Projects Agency (ARPA). By the late
19770s it had grown into a global communication network. In the late 1980s and
early 1990s, commercial interest in the Internet began to blossom. You have to
admit that it has been a phenomenal growth. Now internet is a part of everything
all over the world. The key technology foundation for the Internet is the TCP/IP
transfer protocol. This is the glue that connects computers around the world
together.
TCP/IP
Transmission Control Protocol/Internet Protocol is the method of data sharing
between computers for all Internet connected computers. This data is broken down
into packets using the Internet Protocol. These packets are sent across the
Internet independently. The TCP protocol provides error resolution to ensure
that all the data has been sent correctly and that the individually packets are
recombined appropriately on the client end. The Internet is a huge, worldwide
interconnection of computers via this TCP/IP protocol. The connections are made
via phone lines and direct leased connections. Typically, an individual will
connect through an Internet service provider (ISP). An ISP will work with a
national service provider to provide high speed connections to the Internet
backbone. As you can guess, the Internet is a huge, controlled by not one
particular country, mind-boggling phenomenon that allows us to connect in a
fashion not strictly controlled or planned out by anybody.
