    Study Notes

    Web Browsers and Web Technology

    • Web browsers are applications that display various types of content on the Internet, including text, images, animations, and videos.
    • The World Wide Web (WWW) relies on technologies such as Web browsers, Hypertext Markup Language (HTML), and Hypertext Transfer Protocol (HTTP).

    Server and Client Communication

    • Web servers process network requests and deliver files to create web pages using HTTP.
    • Servers operate in a "passive open" state, waiting for client connections, while clients initiate connections through TCP synchronization messages (SYN).
    • A reliable connection is established via a three-way handshake involving SYN, SYN-ACK, and ACK messages.
    • Retransmission ensures reliability by resending lost data packets within a defined timeout period, driven by ACK value verification.

    Cybersecurity and IP Addresses

    • IP addresses uniquely identify devices connected to the Internet, facilitating data location and retrieval.
    • Public IP addresses identify external devices connecting to the ISP, typically the router for internet access.
    • Private IP addresses are assigned within a local network and managed by routers for devices connected to it.

    Web Development Technologies

    • HTML structures and displays content on web pages.
    • CSS enhances visual appearance by adding colors and styles.
    • JavaScript enables interactive features and animations on web pages.
    • Backend technologies and database systems support server-side functionality and data management.

    Concepts of Cyberspace

    • Cyberspace exists wherever the Internet is utilized, including online gaming platforms, creating digital realms without physical counterparts.

    Cybersecurity Layers

    • A layered cybersecurity approach involves protecting mission-critical assets against malicious threats.
    • URL (Uniform Resource Locator) consists of various parts defining the location and retrieval mechanism for web resources.

    Web Browsers and Servers

    • Popular web browsers: Chrome, Internet Explorer, Firefox, Apple Safari, Opera.
    • Web hosting provides services for individuals and businesses to store and access web pages on the Internet.

    Internet vs. Web

    • The Internet is a vast network of interconnected computers enabling global communication and resource access.

    Data Management

    • Data management encompasses collecting, storing, utilizing, and overseeing data as an enterprise asset for secure and efficient usage.
    • Benefits of data governance include improved decision-making, cost control, regulatory compliance, enhanced trust, risk management, and data accessibility.

    Cybersecurity Challenges in 2023

    • Ransomware has evolved into a significant threat, utilizing data encryption for extortion purposes while prompting increased security measures to combat it.
