Technology Infrastructure:
The Internet and the
World Wide Web
Types of Networks
• A local area network (LAN) is a network of
computers close together.
• A wide area network (WAN) is a network of
computers connected over a great distance.
Switched Networks
• The Internet uses packet switching
• Files are broken down into small pieces (called
packets) that are labeled with their origin,
sequence, and destination addresses.
Routing Packets
• The computers that decide how best to
forward each packet in a packet-switched
network are called ‘routers’.
• The programs on these routers use ‘routing
algorithms’ to determine the best path to
send each packet.
• These routers and the telecommunication
lines connecting them are referred to as ‘the
Internet backbone’.
Internet Protocols (IP)
• A protocol is a collection of rules for formatting,
ordering, and error-checking data sent across a
network.
• ARPANET is the earliest packet-switched
network.
• The open architecture of this experimental
network used Network Control Protocol (NCP)
which later became the core of the Internet.
TCP/IP
• The Transmission Control Protocol (TCP) and the
Internet Protocol (IP) are the two protocols that
support the Internet operation (commonly referred to
as TCP/IP).
• The TCP controls the disassembly of a message into
packets before it is transmitted over the Internet and
the reassembly of those packets when they reach
their destination.
• The IP specifies the addressing details for each
packet being transmitted.
Domain Names
• To make the numbering system easier to use,
an alternative addressing method that uses
words was created.
• An address, such as www.course.com, is
called a domain name.
URL (Uniform Resource
Locator)
• Internet address
• Three parts
• Protocol (how file will be sent)
• Domains (computer path to file)
• File pathname (folders and filename)
Sample URL
http://www.petrozello.com/petrozello/index.html
domains
protocol
(HyperText
Transfer Protocol)
folder
file extension
file pathname
Hypertext Markup Language
• HTML is a simplified subset of SGML
(Standard Generalized Markup Language)
that includes tags defining the format and
style of text elements in a document.
• HTML now includes tags for tables, frames,
and other features that help Web designers
create more complex page layouts.
HTML Tags
• Tags are codes that are used to define where
an HTML element starts and (if necessary)
where it ends.
• In an HTML document, each tag is enclosed
in brackets (<>).
• A two-sided tag set has an opening tag and a
closing tag.
Nested Information
• Tags work in pairs
• Nest the pairs
<B><I><u> for emphasis </I></B></u>
Unknown results!
<B><I><u> for emphasis</u> </I></B>
for emphasis
Scripting Language and Style
Sheet Capabilities
• Web designers can use the OBJECT tag to
embed scripting language codes in HTML
pages (this is also called client-side scripting).
• Scripts can execute programs on computers
that display those pages.
• Cascading Style Sheets (CSS) let designers
define formatting styles that can be reapplied
to multiple Web pages.

Electronic Commerce
• Electronic Funds Transfers (EFTs) have
been used by banks for many years.
• Electronic Data Interchange (EDI) occurs
when one business transmits computerreadable data in a standard format to
another business.
Example of Using EDI
Purchase orders to order steel for production
Notify shipments
GM
USX
Billing
Notify bank to
transfer money to
USX’s account
Notify orders

Electronic Data Interchange (EDI)
The primary goals of EDI are:
Cut the transaction cost
Speed up the ordering process

There are two important considerations:
Establishing the physical link
Transferring data in a format compatible to
all users
Advantages of E-Commerce
• Cut data handling cost
• Easier to search for data and compare
offerings
• Electronic commerce increases sale
opportunities for the seller. Web advertising
reaches a large amount of potential
customers throughout the world.
Disadvantages of E-Commerce
• Some business processes are difficult to be
implemented through electronic commerce.
• Computers are needed - Computers are not
as portable as catalog
• There are concerns about security provisions
on the internet
• Businesses face cultural and legal obstacles to
conducting electronic commerce.
