This article discusses how two real estate agents, Cal Carter and Chuck Roberts, effectively generate leads through their internet presence. Carter focuses on organic search engine optimization to drive traffic to his website, which attracts 200,000 unique visitors annually and yields 20 solid registrations per day. He nurtures these leads through a multi-week email drip campaign. Roberts alternately uses search engine marketing to bid on key search terms and drive traffic. Both agents emphasize the importance of ongoing maintenance, testing, and adjustments to maximize their online lead generation strategies. Their approaches align with SHIFT tactics to re-margin their business through expense management and leverage technology.
To manage productivity and contain costs, companies should focus on labour and space by cross-training employees rather than downsizing, and subletting excess space.
Establishing strong supplier partnerships, reviewing storage methods, and outsourcing non-core functions can maximize supply chain efficiencies. Regular cycle counts using mobile technologies can also improve accuracy and visibility.
As the economy grows, supply chain managers must ensure they have the right staffing to handle current and future operations, especially replacing soon-to-retire senior executives, in order to build bench strength and carry institutional knowledge forward. A cost analysis can also help optimize margins by identifying unprofitable clients.

WWW, the world wide web or shortly the web - really nothing more than an information service on the Internet – has changed our world by creating a whole new digital world that is closely intertwined with our real world, making reality what was previously unimaginable: communication across the world in seconds, watching movies on a smartphone, playing games or looking at photos with remote partners in distant continents, shopping or banking from your couch … In our course on Internet and web technologies you will learn how it all works.
We start off by introducing the underlying technologies of the web: URI, HTTP, HTML, CSS and XML. If this sounds cryptic, rest assured that you will soon become familiar with what it’s all about. We will then focus on web services and web programming technologies along with their practical application. And we will look at how search engines – our fast and reliable signposts in the digital world – actually work to find contents and services on the web. The course concludes with a look at cloud computing and how it is changing the way we will access computing power in the future.
Techniques to Control Memory Hogging by Web Browsers: An in-Depth Review
The Web Browser is to date a popular piece of software in modern computing systems. They are the main interface for vast information access from the Internet. Browsers technologies have advanced to a stage where they do more than before. They now parse not only plaintext and Hypertext Markup Language (HTML), but also images, videos and other intricate protocols. These advancements have increased demand for memory. This increased demand poses a challenge in multiprogramming environments. The contemporary browser reference model does not have a memory control mechanism that can limit maximum memory a browser can use. This leads to hogging of memory by contemporary browsers. This paper is a review on emergent techniques that have been used to control memory hogging by browsers based on the contemporary reference architecture. We review major browsers architectures including Mozilla Firefox, Google Chrome and Internet explorer. We give an in-depth study on techniques that have been adopted with a view to solve this problem. From these reviews we derive the weaknesses of the contemporary browser architecture and inefficiency of each technique used.

115. Internet Characteristics
• Analogy: Human Characteristics that really
matter:
– Humans walks on two legs
– Humans have a 3lbs brain.
– Humans communicate with speech and written
words
116. Internet Characteristics
• Internet characteristics that really matter:
– Internet uses packet switching –
• data is broken into little packets that have to re-
assembled
– Internet uses TCP/IP protocol –
• robust protocol for sending everything from email to
video
– Internet used IP addresses
117. Innovation Phase: 1961-1974
• All the technology was invented
– Paul Baran proposed the idea of packet switching
for network communication (1962)
– Vinton Cerf Proposed TCP/IP Protocol in 1974
118. Institutional Phase: 1980-1993
• ARPANet: A purely military network got turned over
to Scientists working on Defense Department
Projects
– National Labs – National Science Foundation
– NASA
– Department of Energy
– Leading Universities
• Over in Europe another large network emerged.
– CERN – Leading particle physics lab (Geneva, Switzerland)
119. Institutional Phase: 1980-1993
• ARPANet and CERN’s network officially
became 100% TCP/IP in 1982
• Standardization – commitment to this
standard protocol allowed software
developers to coordinate networking efforts.
• In many ways, this marks the birth of the
Internet we now know.
120. E-commerce Phase: 1995-today
• Prior to 1995, the Internet facilitated B2B e-
commerce (which is really e-business).
– But the systems developed were very specialized and
isolated.
• True E-commerce wasn’t realized until the end
consumer got Internet access.
• In 1995, we saw the explosion of Internet Service
Providers (ISPs)
– AOL
– Dialup Providers
121. ISPs of Today
• Telephone companies own most of the
infrastructure. They are the global players
– They farm it out to local ISPs
• Cable TV providers are now the biggest local
players.
• Dialup Still exists
– AOL
– Netzero
122. Part 1: Internet History & Details
• Network of networks built on standardized
technology and protocols.
• Until the Internet emerged…different groups
were using all different kinds of protocols.
• Key Term: Protocol
– a set of rules governing the format of messages
that are exchanged between computers
124. Why is Packet Switching important?
• Otherwise you need a direct, uninterupted
connection, which is not feasible.
– Network goes down all the time.
– Traffic gets re-routed on the fly
• Also, its higher performance.
– Your packets could take numerous paths in
parallel.
126. Why is TCP/IP so important
• The Internet would never have expanded so
rapidly without a commitment to Global
Standardization
• Its hard to get experts to agree on a single
Protocol
• TCP/IP is very robust and allows for numerous
levels of sub-networks.
127. IP Address
• 32-bit number
– Uniquely identifies devices on the Internet
• 192.168.120.227
– 4 billion unique devices.
• There are already more than 4 billion devices:
– Sub-netting –
• one IP address gets you to a subnet
• Subnet uses its own internal IP address.
128. Sub-Networks
• IP Addresses are a commodity, limited supply.
• Controlled by ICANN, which indirectly came from the
Gore Bill.
• Siena gets Internet Access from Time Warner
Cable…we probably pay for 20-40 IP Addresses,
which are reserved for key server
– Web server
– Blackboard server
– Mail server.
• How do the other 4000 computers communicate?
129. Internal Sub-netting
• Outside of Siena, you can’t reach
computer A and B directly.
• Instead, you contact the router
(Real IP) and also indicate
A or B’s Internal IP.

World)

130. Internal Sub-netting
• Siena’s router is programmed so that
A and B can directly communicate
using Internal IPs (sub-net).
• If A needs to reach a computer C
outside of Siena, then the router
modifies the packet headers
to indicate the Siena Router’s
Real IP address and
the Internal IP of A.
• Thus, C will know
how to reach A.

132. Part 2: World Wide Web (WWW)
• Remember: There are companies that use the
Internet to connect two computers, yet these
computers are not part of the WWW.
• To be part of the world wide web, you need a
URL
– Uniform Resource Locator (not universal)
134. URL Concept
• Internet IP Address are meaningless
– There is no organization
– No geographic significance
– No organizational significance
• Create a meaningful name that is an alias for
an IP Address
– Given a URL create a system to find the IP Address
(DNS lookup).
139. ICANN
• Internet Corporation for Assigned Numbers
and Networks.
• Global coordinator of IP Address and Domain
names.
• Registrars like GoDaddy are “licensed” by
ICANN to register domain names.
• Large Internet Providers (ISPs) also “secure” IP
addresses and farm them out to smaller ISPs.
140. Map of the Internet (US)
• http://www.cs.siena.edu/~ebreimer/courses/c
sis-116-s07/Internet_map_labels.pdf
• The above is a partial map as seen from one
location (Lumeta.com).
141. USA: Pioneers of the Internet
• The United States pioneered the Internet, and thus,
“owns” the largest chunk of the infrastructure.
• Western Europe, Japan, and Australia were quick to
follow.
• Eastern Europe, Russia and China are just getting
established
• Parts of Asia are next: India
• South America is coming along
• Africa may be decades away
142. Part 2: Activities
• Do some surfing and try to find a URL with a
sub-domain.
• How much does it cost to register a domain
name for .com, .net, .us?
• Thinking of registering a domain name for
your project? See if the one you want is
available?
144. Protocols of the WWW
• HTTP / HTTPS – Hypertext Transfer Protocol
(Secure)
• FTP / SFTP – (Secure) File Transfer Protocol
• SMTP – Simple Mail Transfer Protocol
• POP – Post Office Protocol
• IMAP – Internet Message Access Protocol
• Telnet – Terminal Emulation

148. Key Technologies
• Hypertext –
– HTML – Hypertext Markup Language
• Markups are used to structure a web page
– CSS – Cascading Style Sheets
• Styles are defined that decorate each structural
element
149. DNS
Domain Name System
• The WWW is supported by a network of DNS
servers
• These server help translate URLs into IP
Addresses.
• Domain Names are a fundamental concept
that is connected to E-commerce.
150. A set is a collection of objects. These objects are
called the elements or members of the set. Objects
can be anything: numbers, people, words, Web
sites, other sets, etc.
151. Given two sets A and B, we say that A is a subset
of B if every element of A is also an element of B.
We write A ⊆ B to denote that A is a subset of B.
For example:
{1} ⊆ {1,2,3}
{2,2,1,3,2,1,3,2} ⊆ {1,2,3}
Let B be the set of registered students at Boston
University, and C be the set of registered students
in CS-103. Then C ⊆ B.
152. Venn Diagrams
A Venn diagram is an illustration that represents
one or more sets and the relationships between
them. For example, suppose A = {1,2,3,4,5} and B =
{3,4,5,6,7,8}. Below is a Venn diagram of A and B:
Venn diagram
153. The union of two sets A and B is the set consisting of any
object that is (1) an element of A, or (2) an element of B, or (3)
an element of both A and B. The union of A and B is written as
A ∪ B.
Examples:
{1} ∪ {2,3} = {1,2,3}
{2} ∪ {2,3} = {2,3}
{ } ∪ {4,6} = {4,6}
A = {1,2,3,4,5}. B = {3,4,5,6,7,8}. A ∪ B = {1,2,3,4,5,6,7,8}.
154. The intersection of A and B is the set of all
objects that are elements of both A and B.
The intersection of A and B is written as A
∩ B.
Examples:
{2} ∩ {2,3} = {2}
{3,2} ∩ {2,3} = {2,3}
{2,3} ∩ {4,6} = { }
A = {1,2,3,4,5}. B = {3,4,5,6,7,8}. A ∩ B =
{3,4,5}.
155. Six-Node Graph graph is a formal mathematical representation of a network ("a
collection of objects connected in some fashion").
Each object in a graph is called a node (or vertex). Corresponding to the
connections (or lack thereof) in a network are edges (or links) in a graph. Each
edge in a graph joins two distinct nodes.
More formally, we define a graph G as an ordered pair G = (V,E) where
V is a set of nodes (vertices).
E is a set of edges (links).
Each edge is a pair of vertices. In other words, each element of E is a pair of
elements of V.
Example: The picture above represents the following graph:
V = {1,2,3,4,5,6}
E = {{1,2},{1,5},{2,3},{2,5},{3,4},{4,5},{4,6}}
G = (V,E)
