    Study Notes

    Internet and Web Technologies

    • An IP address is a numerical label assigned to each device connected to a computer network, expressed in a natural language format (e.g., www.nytimes.com)
    • The Domain Name System (DNS) is a system of servers that store mappings between domain names and IP addresses

    Client-Server Computing

    • A model of computing where powerful personal computers (clients) are connected in a network with one or more servers
    • Servers perform common functions for clients, such as storing files, software applications, and providing access to printers

    Cloud Computing

    • A model of computing where firms and individuals obtain computing power and software applications over the Internet, rather than purchasing and installing them on their own computers
    • Powerful servers manage data storage and processing "in the cloud"

    Internet of Things (IoT)

    • The use of the Internet to connect a wide variety of devices, machines, and sensors, each with unique IP addresses
    • Examples of IoT devices include cars, machines, lightbulbs, and thermostats with sensors that collect data and connect to the Internet

    World Wide Web (WWW)

    • The WWW was invented by Tim Berners-Lee at CERN in 1989-1991
    • Initial versions of HTML, HTTP, and the Web server were built, consisting of four essential components of the Web
    • The initial Web was text-only, with the introduction of Mosaic Web browser with a Graphical User Interface (GUI) in 1993

    Web 2.0 Features and Services

    • Online Social Networks, such as Facebook, LinkedIn, Twitter, and Pinterest, rely on user-generated content and emphasize sharing of content
    • Blogs are personal Web pages of chronological entries created by individuals or corporations to communicate with readers

    Packet Switching and Routing

    • Packet switching slices digital messages into packets, sending them along different communication paths as they become available, and reassembling them at the destination
    • Packets use routers, special-purpose computers that interconnect computer networks, to route packets and ensure efficient and error-resistant transmission

    Transmission Control Protocol (TCP) and Internet Protocol (IP)

    • TCP establishes connections among sending and receiving Web computers, handling assembly of packets at the point of transmission and reassembly at the receiving end
    • IP provides the Internet's addressing scheme and is responsible for the actual delivery of packets, using IP addresses (e.g., 124.49.64.91)
