It consists of private, public, academic and government networks that use technologies like WiFi, fiber optics, and cellular networks. The Internet allows access to resources like websites, emails, files sharing, social media, and video calls. It originated from US government research in the 1960s and experienced commercial growth in the 1990s with the introduction of the World Wide Web. The Internet has transformed how people communicate, access information, work, learn, share, and socialize. It also presents challenges around security, privacy, and surveillance.
The document discusses the key concepts and components of how the internet works. It explains that the internet connects millions of private networks run by companies, universities, and government agencies. It also describes some of the main ways people access the internet, such as through a modem, local area network, or high-speed connection. Additionally, it outlines several common internet tools and protocols used for communication online, including web servers, clients, browsers, and IP addressing.

The global information infrastructure
Section:
GETTING ON BOARD THE INTERNET
From the Internet toward Worldwide Commerce
The Internet offers many resources, but its lack of robustness in service, security, and reliability renders it an interim solution to a true global information infrastructure (GII) that supports worldwide commerce. The development of such an infrastructure depends on more than improvements in technology however; for the GII to be commercially robust, issues concerning regulations, security, and cultural diversity must also be resolved.
The Global Information Infrastructure (GII) is defined as an environment that uses high-performance hardware, software, and communications to deliver voice, data, video, graphics and other information regardless of where the information or user is located.
The GII will be the information highway of the future. Today, the infrastructure is the Internet. This article describes the Internet and, from time to time, moves forward to the GII. The components of the information highway -- people, communications media, communications networks, data bases, agents, information providers, and bridges -- and their interrelationships are shown in Exhibit 1.
THE INTERNET: USERS AND APPLICATIONS
The exact number of Internet users is not known. Estimates range from 10 to 100 million users with interconnecting networks stretched around the world. In 1994, there were approximately 20,000 networks in the US, and 1,500 each in the UK, Germany, and Japan. In countries such as Russia, South Africa, and South Korea, networks numbered in the several hundreds. In developing countries such as China, Kuwait, and Egypt, three to five networks were typically operational.
Current Internet applications include:
· Find/learn -- through data bases and descriptions.
· Talk -- through E-mail, voice, and video.
· Work -- accomplished through cooperative work, telecommuting, and videoconferences.
· Shop --using catalogs and electronic malls.
· Play -- using games and video on demand.
· Invest -- through stock market advice, order placement, and money management.
INTERNET SERVICES
Internet applications are delivered through a variety of services (see Exhibit 2).
E-Mail. E-mail, for example, provides capabilities for sending messages addressed to individuals or to mailing lists. It is much faster and less costly than traditional postal services. However, Internet E-mail goes through multiple nodes and is subject to delay. Furthermore, there is no address directory.
Newsgroups are a natural extension of E-mail. They allow users to post messages for anyone to read. Another extension of E-mail is computer conferencing. In essence, a computer conference is a file devoted to a specific topic being discussed by a group of people.
Telnet. Telnet allows users to access a remote computer as though it were a local machine. Regardless of where they are located, users can retrieve E-mail messages and download them to the local computer. Typ ...

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.

How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Why learn about the internet 7
1. Why Learn About the Internet?
To say that the Internet has had a big effect on organizations of all types and sizes
would be a huge understatement. Since the early 1990s, when the Internet was first
used for commercial purposes, it has affected all aspects of business. Businesses use
the Internet to sell and advertise their products and services, reaching out to new
and existing customers. If you are undecided about a career, you can use the Internet
to investigate career opportunities and salaries using sites such as
www.monster.com and HotJobs at www.yahoo.com. Most companies have Internet
sites that list job opportunities, descriptions, qualifications, salaries, and benefits. If
you have a job, you probably use the Internet daily to communicate with coworkers
and your boss. People working in every field and at every level use the Internet in
their jobs. Purchasing agents use the Internet to save millions of dollars in supplies
every year. Travel and events-management agents use the Internet to find the best
deals on travel and accommodations. Automotive engineers use the Internet to work
with other engineers around the world developing designs and specifications for new
automobiles and trucks. Property managers use the Internet to find the best prices
and opportunities for commercial and residential real estate. Whatever your career,
you will probably use the Internet daily. This chapter starts by exploring how the
Internet works and then investigates the many exciting opportunities for using the
Internet to help you achieve your goals.
Internet
A collection of interconnected
networks, all freely exchanging
information.
USE AND FUNCTIONING OF THE INTERNET
ARPANET
A project started by the U.S. Department
of Defense (DoD) in 1969 as
both an experiment in reliable networking
and a means to link DoD
and military research contractors,
including many universities doing
military-funded research.
Internet Protocol (IP)
A communication standard that
enables traffic to be routed from one
network to another as needed.

Accessing the Internet
Several Ways to Access the
Internet
Users can access the Internet in
several ways, including using a
LAN server, dialing into a server
using the telephone lines, using a
high-speed service, or accessing
the Internet over a wireless
network.
Connect via LAN Server
This approach is used by businesses and organizations that manage a local area network
(LAN). By connecting a server on the LAN to the Internet using a router, all users on the
LAN are provided access to the Internet. Business LAN servers are typically connected to the
Internet at very fast data rates, sometimes in the hundreds of Mbps. In addition, you can
share the higher cost of this service among several dozen LAN users to allow a reasonable cost
per user.
Connect via Dial-up
Connecting to the Internet through a dial-up connection requires a modem that allows the
computer to use standard phone lines. The modem then contacts a server managed by the
Internet service provider (ISP). Dial-up connections use TCP/IP protocol software plus Serial
Line Internet Protocol (SLIP) or Point-to-Point Protocol (PPP) software. SLIP and PPP are
two communications protocols that transmit packets over telephone lines, allowing dial-up
access to the Internet. After the connection is made, you are on the Internet and can access
any of its resources. Dial-up is considered the slowest of connections because it is restricted
3. by the 56 Kbps limitation of traditional phone line service. A dial-up connection also ties up
the phone line so that it is unavailable for voice calls.
Connect via High-Speed Service
Several “high-speed” Internet services are available for home and business. They include cable
modem connections from cable television companies, DSL connections from phone companies,
and satellite connections from satellite television companies. These technologies were
discussed in Chapter 6. High-speed services provide data transfer rates between 1 and 7 Mbps.
Unlike dial-up, high-speed services provide “always connected” service that does not tie up
the phone line.
Connect Wirelessly
In addition to connecting to the Internet through wired systems such as phone lines and
television cables, wireless Internet access is very popular. Thousands of public Wi-Fi services
are available in coffee shops, airports, hotels, and elsewhere, where Internet access is provided
free, for an hourly rate, or for a monthly subscription fee. Wi-Fi is even making its way into
aircraft, allowing business travelers to be productive during air travel by accessing e-mail and
corporate networks.6
Cell phone carriers also provide Internet access for handsets or notebooks equipped with
connect cards. New 3G mobile phone services rival wired high-speed connections enjoyed
at home and work. Sprint, Verizon, AT&T, and other popular carriers are working to bring
4G service to subscribers soon. 4G cell phone service will compete strongly against today’s
wired services. Wireless devices also require specific protocols and approaches to connect.
Internet Service Providers
Internet service provider (ISP)
Any company that provides Internet
access to people or organizations
THE WORLD WIDE WEB
World Wide Web
A collection of tens of millions of
server computers that work together
as one in an Internet service using
hyperlink technology to provide
information to billions of users.
hyperlink
Highlighted text or graphics in a Web
document that, when clicked,
opens a new Web page or section of
the same page containing related
content.
Web browser
Web client software such as Internet
Explorer, Firefox, and Safari used to
view Web pages.
Hypertext Markup Language
(HTML)
The standard page description
language for Web pages.
HTML tags
Codes that let the Web browser
know how to format text—as a
heading, as a list, or as body
text—and whether images, sound,
and other elements should be
inserted.
4. Extensible Markup Language
(XML)
The markup language for Web
documents containing structured
information, including words,
pictures, and other elements.
Cascading Style Sheet (CSS)
A file or portion of an HTML file that
defines the visual appearance of
content in a Web page.
Web 2.0 and the Social Web
Web 2.0
The Web as a computing platform
that supports software applications
and the sharing of information
between users.
rich Internet application
Software that has the functionality
and complexity of traditional application
software, but does not
require local installation and runs in
a Web browser.
Web Programming Languages
Java
An object-oriented programming
language from Sun Microsystems
based on C++ that allows small programs
(applets) to be embedded
within an HTML document.
Developing Web Content
The art of Web design involves working within the technical limitations of the Web and
using a set of tools to make appealing designs. Popular tools for creating Web pages and
managing Web sites include Adobe Dreamweaver, Microsoft Expression Web, and Nvu. (See
Figure 7.8.) Today’s Web development applications allow the user to create Web sites using
software that resembles a word processor. The software includes features that allow the developer
to work directly with the HTML code or use autogenerated code. Web development
software also helps the designer keep track of all files in a Web site and the hyperlinks that
connect them.
Web Services
Web services
Standards and tools that streamline
and simplify communication among
Web sites for business and personal
purposes.
Internet and web application
search engine
A valuable tool that enables you to
find information on the Web by specifying
words that are key to a topic of
5. interest, known as keywords.
Business Uses of the Web
In 1991, the Commercial Internet Exchange (CIX) Association was established to allow
businesses to connect to the Internet. Since then, firms have been using the Internet for a
number of applications, as discussed in this section.
E-mail, Instant Messaging, and Video Chat
. E-mail is no longer limited to simple text messages. Depending on your hardware and software
and the hardware and software of your recipient, you can embed images, sound, and
video in a message and attach any kind of file. The authors of this book, for example, attached
instant messaging
A method that allows two or more
people to communicate online using
the Internet
Career Information and Job Searching
The Internet is an excellent source of job-related information. People looking for their first
job or seeking information about new job opportunities can find a wealth of information.
Search engines can be a good starting point for searching for specific companies or industries.
You can use a directory on Yahoo’s home page, for example, to explore industries and careers.
Most medium and large companies have Internet sites that list open positions, salaries, benefits,
and people to contact for further information. The IBM Web site, www.ibm.com, has
a link to “Jobs at IBM.” When you click this link, you can find information on jobs with
IBM around the world. Some Internet sites specialize in certain careers or industries. The
site www.directmarketingcareers.com lists direct marketing jobs and careers. Some sites can
help you develop a résumé and find a good job. They can also help you develop an effective
cover letter for a résumé, prepare for a job interview, negotiate an employment contract,
and more. In addition, several Internet sites specialize in helping you find job information
and even apply for jobs online, including www.monster.com, www.hotjobs.com, and
Telnet, SSH, and FTP
File Transfer Protocol (FTP)
A protocol that describes a file
transfer process between a host and
a remote computer and allows
users to copy files from one computer
to another.
6. Web Log (Blog), Video Log (Vlog), and Podcasting
Web log (blog)
A Web site that people can create
and use to write about their observations,
experiences, and feelings
on a wide range of topics.
Usenet and Newsgroups
Usenet is an older technology that uses e-mail to provide a centralized news service. Topic
areas in Usenet are called newsgroups. A newsgroup is essentially an online discussion group
that focuses on a particular topic. Newsgroups are organized into various hierarchies by
general topic, and each topic can contain many subtopics. Table 7.7 provides some examples.
Usenet is actually a protocol that describes how groups of messages can be stored on and sent
between computers. Following the Usenet protocol, e-mail messages are sent to a host computer
that acts as a Usenet server. This server gathers information about a single topic into a
central place for messages. A user sends e-mail to the server, which stores the messages. The
user can then log on to the server to read these messages or have software on the computer
log on and automatically download the latest messages to be read at leisure. Thus, Usenet
forms a virtual forum for the electronic community, and this forum is divided into
newsgroups. Blogging, RSS, and social networking sites have drawn many users away from
Usenet forums.
Chat Rooms
chat room
A facility that enables two or more
people to engage in interactive
“conversations” over the Internet.
Internet Phone and Videoconferencing Services
Internet phone service enables you to communicate with others around the world. This
service is relatively inexpensive and can make sense for international calls. With some services,
you can use the Internet to call someone who is using a standard phone. You can also keep
your phone number when you move to another location. According to one Internet phone
user who moved from Madison, Wisconsin, to Californ
Social Networks
Social networking Web sites provide Web-based tools for users to share information about
themselves with people on the Web and to find, meet, and converse with other members.
The most popular social networking sites are MySpace and Facebook. Both sites provide
members with a personal Web page and allow them to post photos and information about
themselves (see Figure 7.15). Social networking sites allow members to send messages to each
Media Sharing
Media-sharing Web sites such as YouTube for video sharing and Flickr for photo sharing
provide methods for members to store and share digital media files on the Web. YouTube
allows members to post homemade video content in categories such as comedy, entertainment,
film and animation, how-to, news, people, pets, sports, and travel. As mentioned
earlier, Flickr allows members to upload photos to their own personal online photo album
and choose photos to share with the community.
Social Bookmarking
Social bookmarking sites are another example of Web 2.0. These sites provide a way for Web
7. users to store, classify, share, and search Web bookmarks—also referred to as favorites. The
typical purpose of social bookmarking sites is to provide a view of the most popular Web
sites, videos, blog articles, or other Web content at any given moment. Often social bookmarking
sites include Web browser add-ons (extensions) that provide a button on the toolbar
for recommending Web content. For example, del.icio.us is a social bookmarking Web site
that provides a “what’s hot right now” button. When you sign up for del.icio.us, you can

music formats such as MP3, discussed in Chapter 3, you can download music from the
E-Books and Audio Books
Digital books, both in text and audio form, are growing in popularity thanks to appealing
devices and services. Amazon’s e-book reader called the Kindle jump-started the e-book
market with its small form factor and high capacity.33 The Kindle wirelessly connects to
Amazon’s e-book service using free wireless service from Sprint to download books, blogs,
newspapers, and periodicals. It can store about 200 books.
Office on the Web
Having an Internet office with access to files and information can be critical for people who
travel frequently or work at home. An Internet office is a Web site that contains files, phone
numbers, e-mail addresses, an appointment calendar, and more. Using a standard Web
browser, you can access important business information. An Internet office allows your
desktop computer, phone books, appointment schedulers, and other important information
to be with you wherever you are.
Internet Sites in Three Dimensions
Some Web sites offer three-dimensional views of places and products. For example, a 3-D
Internet auto showroom allows people to select different views of a car, simulating the experience
of walking around in a real auto showroom. (See Figure 7.18.) When looking at a
8. 3-D real estate site on the Web, people can tour the property, go into different rooms, look
at the kitchen appliances, and even take a virtual walk in the garden. Map Web sites and
Internet-powered software like Windows Live Search and Google Earth provide views of
cities and locations in a 3-D environment.34 Second Life provides an
Other Internet Services and Applications
Other Internet services are constantly emerging. A vast amount of information is available
over the Internet from libraries. Many articles that served as the basis of the sidebars, cases,
and examples used throughout this book were obtained from university libraries online.
Movies can be ordered and even delivered over the Internet. The Internet can provide critical
information during times of disaster or terrorism. During a medical emergency, critical

tunneling
The process by which VPNs transfer
information by encapsulating traffic
in IP packets over the Internet.
NET ISSUES
Management issues. Although the Internet is a huge, global network, it is managed at
the local level; no centralized governing body controls the Internet. Preventing attacks is
always an important management issue. Increasingly, states are proposing legislation to
help collect sales tax from Internet sales.
• Service and speed issues. The growth in Internet traffic continues to be significant.
Traffic volume on company intranets is growing even faster than the Internet. Companies
setting up an Internet or intranet Web site often underestimate the amount of computing
power and communications capacity they need to serve all the “hits” (requests for pages)
they get from Web cruisers.
• Privacy, fraud, security, and unauthorized Internet sites. As use of the Internet grows,
privacy, fraud, and security issues become even more important. People and companies
are reluctant to embrace the Internet unless these issues are successfully addressed.
Unauthorized and unwanted Internet sites are also problems some companies face. A
competitor or an unhappy employee can create an Internet site with an address similar
to a company’s. When someone searches for information about the company, he or she
might find an unauthorized site instead. While the business use of the Web has soared,
online scams have put the brakes on some
