    Study Notes

    E-commerce Infrastructure

    • E-commerce encompasses business, technology, and society aspects.
    • Key learning objectives for chapter 3 include discussing internet origins, current structure, web functionality, e-commerce support services, and mobile application impact.

    The Internet: Technology Background

    • The internet is a vast network of interconnected networks and computers.
    • It connects businesses, educational institutions, and individuals.
    • The World Wide Web (web) is a popular service within the internet, providing access to billions of web pages.

    The Internet: Key Technology Concepts

    • The Internet is a network that utilizes IP addressing and TCP/IP.
    • It provides services to users similar to a phone system.
    • Key concepts include packet switching, TCP/IP communication, and client/server computing.

    Packet Switching

    • Digital messages are sliced into packets.
    • Packets follow various paths and are reassembled at their destination.
    • Packet switching uses routers and is less costly than circuit switching.

    TCP/IP Protocol Suite

    • A large set of protocols, primarily TCP and IP.
    • Transmission Control Protocol (TCP) manages connections and packet assembly/reassembly.
    • Internet Protocol (IP) handles addressing and packet delivery.
    • Other protocols like UDP provide alternatives. Four layers: Network Interface, Internet, Transport, and Application Layers.

    Internet (IP) Addresses

    • IPv4 is a 32-bit number, broken into four sets of numbers (e.g., 201.61.186.227).
    • IPv6 utilizes 128-bit addresses, supporting significantly more addresses than IPv4.

    Domain Names System (DNS) and Uniform Resource Locators (URLs)

    • DNS allows users to type in domain names (e.g., www.google.com) instead of numeric IP addresses.
    • URLs provide web browsers with addresses to find content on the internet.

    Client/Server Computing

    • Clients request services and resources from servers (e.g., web page access, file sharing).
    • Servers provide these services and resources to multiple clients, in a centralized manner.

    The Mobile Platform

    • Smartphones and tablets are primary internet access tools.
    • Mobile internet access can be telephone-based or wireless based.

    The Internet, Cloud Computing Model

    • Cloud computing utilizes many virtual resources over the internet.
    • Three main service types: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

    The Internet Backbone

    • Composed of fiber-optic cables, which transmit data using light.
    • Includes Tier 1 (transit) ISPs, Tier 2 and Tier 3 providers.
    • Internet Exchange Points (IXPs) are regional hubs connecting various providers.

    Wi-Fi Networks

    • Wireless technologies allowing users to access the internet.

    The Internet of Things (IoT)

    • Objects are connected to the internet using sensors and RFID technology.
    • Uses low-cost sensors and data analytics software.
    • IoT creates "smart" connected things. Concerns include interoperability, security and privacy.

    The Web

    • The World Wide Web was invented in 1989-1991 by Tim Berners-Lee.
    • Key elements: HTML, HTTP, web servers and browsers.
    • Early browsers: Mosaic, Netscape Navigator, and Microsoft Internet Explorer.

    Hypertext

    • Text with embedded links that connect documents.
    • Uses hypertext transfer protocol (HTTP) and uniform resource locators (URLs) to locate resources.

    Markup Languages

    • HTML: Defines how web page elements are formatted and displayed.
    • CSS: Used to add styling to HTML pages.
    • XML: An information description language

    Web Servers and Clients

    • Web servers deliver requested HTML pages via HTTP protocol.
    • Clients are devices capable of requesting and displaying web pages.
